Understanding your blood values: Your path to better health and well-being

Do you often feel tired, lack motivation, or struggle with symptoms you cannot explain—such as weight problems or blemished skin? These are often signals from your body, and the answers usually lie in your blood values. You can think of them as your body's dashboard: they provide precise data about your metabolism, nutrient levels, and hormonal balance.

What your blood values really reveal about you

Blood values are so much more than just dry numbers on a lab report. They are a direct line to what is happening inside you and tell the story of your current health. Each individual value is like a puzzle piece, revealing how well your organs are working, whether your immune system is currently working at full capacity, or whether you may be lacking important vitamins and minerals.

As soon as you understand what these numbers mean, you take control yourself. You move away from passively guessing and take an active role, allowing you to take targeted action for your health.

Insights that can transform your well-being from the ground up

Imagine finally being able to find the true cause of your constant exhaustion simply by checking your iron or vitamin B12 levels with a nutrient test. Or understanding why you are not losing weight despite exercising and eating well, because a look at your thyroid levels in a hormone test reveals an undetected underactive thyroid. This is exactly where mybody-x home tests come in.

Your blood values are not a definitive diagnosis, but an incredibly valuable snapshot. They are the perfect starting point for asking the right questions and finding the causes behind your symptoms—instead of treating only the symptoms themselves.

We can also see just how crucial early detection through blood tests is on a large scale. Regular monitoring of important blood values has demonstrably helped reduce coronary heart disease in Germany. Between 2017 and 2022, the number of people affected fell by 7.8 percent, equivalent to around 108,000 patients. Experts agree that this is primarily due to better prevention through monitoring cholesterol and blood sugar. You can read more about how blood tests help prevent heart disease at medlabportal.de.

The simple way to greater clarity with mybody-x

The path to this important information no longer has to be complicated. With mybody-x home tests, you can quickly and easily gain clarity about your health from the comfort of your own home. Whether it concerns nutrient deficiencies, food intolerances, or a hormonal imbalance, you receive precise results from a certified German specialist laboratory delivered directly to your home.

Our goal is to help you finally understand the language of your body. This guide takes you step by step through the most important blood values and shows you how to use these insights with a suitable hormone, nutrient, or intolerance test from mybody-x to take an active role in your well-being.

Decoding the complete and differential blood count

A blood count is the absolute classic among blood tests. It is often the very first step when you really want to get to the bottom of your well-being and understand what is going on in your body. But what do terms such as leukocytes, erythrocytes, or thrombocytes actually mean for your everyday life? Let’s break it down in an easy-to-understand way.

Imagine your blood as a huge, pulsating city. A blood count is like taking stock: It counts the different “residents”—your blood cells—and gives us a precise overview of whether all teams are properly staffed and doing their jobs.

The key players in your blood

The three most important cell types we examine in a complete blood count are, so to speak, your body's own special forces. Each of these types has its own vital task that directly influences your energy levels, defenses, and overall strength.

• Erythrocytes (red blood cells): These are your body's hardworking oxygen taxis. They pick up oxygen in the lungs and deliver it to every single cell. This is the only way your muscles and organs can produce energy at all. A deficiency therefore often manifests as persistent fatigue and paleness.

• Leukocytes (white blood cells): They are your personal security team. As part of the immune system, they are always on patrol, fighting viruses, bacteria, and other intruders that want to harm you. An elevated count is often a clear sign of an acute infection or inflammation.

• Thrombocytes (platelets): This is your internal repair team. When you get injured, they rush to the site, ensure blood clotting, and “patch up” the wound. If something is wrong here, it can affect your tendency to bleed.

The following table gives you a quick overview of the most important components of a complete blood count, their function, and what deviations may mean.

Important values in a complete blood count and what they mean

Blood value	Function in the body	Possible causes of low levels	Possible causes of high levels
Erythrocytes	Oxygen transport	Blood loss, iron/vitamin deficiency, kidney disease	Dehydration, smoking, living at high altitude
White blood cells	Immune defense	Viral infections, medications, severe bacterial infections	Bacterial infections, inflammation, stress
Platelets	Blood clotting	Viral infections, autoimmune diseases, vitamin B12 deficiency	Inflammation, iron deficiency, after surgery
Hemoglobin (Hb)	Oxygen binding	Iron deficiency (anemia), bleeding, chronic illnesses	Dehydration, lung diseases, smoking
Hematocrit (Hct)	Proportion of blood cells	Anemia, overhydration	Dehydration, intense physical exertion

Of course, these values are only a first indication. Only when considered together do they provide a clear picture of your body's condition.

From a basic to a complete blood count

While the complete blood count therefore counts the number of the three main players, it takes the analysis one decisive step further. It zooms in closely on the white blood cells and divides them into their specialized units, such as lymphocytes, monocytes, and granulocytes.

This detailed analysis, also called a differential blood count, provides much more precise information about the type of immune response. For example, experts can better assess whether your body is currently fighting a virus or dealing with a bacterial infection. If you want to take a deeper dive, read our article on what exactly is examined in a complete blood count.

The complete blood count is like a specialized investigation of your body's own defense force. It reveals not only that your immune system is active, but also provides clues as to why it is active.

A key value that plays a huge role in both blood counts is hemoglobin (Hb). This is the red blood pigment that binds oxygen in red blood cells—essentially the “tank” of your oxygen taxis. If this tank is too small, too little oxygen reaches the cells. The result: chronic fatigue and reduced performance. A classic sign of iron deficiency.

Important to know: The reference ranges for these parameters are not set in stone. They can vary depending on sex, age, and even lifestyle. For example, the white blood cell count in adults is normally between 4.4 and 11.3 thousand/µl, while the hemoglobin level in men (13.5–18.0 g/dl) is on average higher than in women (11.5–16.4 g/dl). Deviations may indicate harmless infections, but they can also point to significant nutrient deficiencies.

This is exactly where it becomes clear why personalized analysis is so valuable. With mybody-x home tests, you can specifically check the markers that are truly relevant to your personal well-being—for example, in a nutrient or hormone test—and understand the results in the context of your individual situation.

Important markers for metabolism and organ function

A blood count gives you a first rough overview, but the truly interesting details lie deeper. Certain blood values are like highly specialized sensors that tell you exactly how your most important organs and your entire metabolism are doing. This is often where the answers lie to questions about unexplained fatigue, weight problems, or a lack of energy.

When you know these levels, you learn to understand your body's signals much earlier and more accurately. This means you do not have to wait until serious problems appear; you can take action yourself.

Checking your liver and kidneys

Your liver and kidneys are your body's central power plants and waste-disposal systems. They detoxify, filter, and keep countless processes running— their health is the foundation of your well-being.

• Liver values (GPT, GOT): Think of your liver as a busy factory. The enzymes GPT (ALT) and GOT (AST) normally work safely inside liver cells. But when these cells come under stress—whether from an unhealthy diet, alcohol, medication, or infections—they become permeable, and the enzymes enter the bloodstream. Elevated levels are therefore a clear warning signal: your liver is overburdened.
• Kidney values (creatinine): Creatinine is a waste product from your muscles that your kidneys have to filter from your blood continuously. If the performance of this filtration system declines, creatinine builds up in your blood. Your creatinine level is therefore a highly important indicator of how well your kidneys are functioning.

The tricky thing is that you often notice an imbalance in these levels only once significant damage has already occurred. That is precisely why early monitoring with a targeted test is so valuable.

The thyroid as the pacemaker of your metabolism

Do you often feel internally overstimulated, constantly cold, or find that your weight fluctuates wildly without having changed anything? The thyroid is often behind this. This small gland has a huge impact because its hormones set the pace for your entire metabolism.

The key blood values for this are:

• TSH (thyrotropin): This is essentially the chief regulator from the brain. A high TSH level means that the brain has to keep “shouting” at the thyroid because it is working too slowly (underactive thyroid).
• fT3 and fT4: These are the actual, active thyroid hormones. They tell your cells how quickly they should burn energy. If these levels are too low, your metabolism runs on low power.

An undetected thyroid dysfunction can severely limit your quality of life. Analyzing these levels in a hormone test is the first step for many people toward finally regaining their energy and inner balance.

Keep Inflammation and Blood Sugar in Check

Two other markers reveal an incredible amount about your overall health and your long-term risks: long-term blood sugar and inflammation markers.

The HbA1c value is your body's “blood sugar memory.” It reflects not just your blood sugar at a single moment, but the average level over the past two to three months. This makes it an invaluable early-warning system for your diabetes risk.

Another equally important value is CRP (C-reactive protein). This value rises whenever inflammation is smoldering somewhere in the body. We often do not notice these “silent inflammations” at all, but over time they can promote chronic diseases. You can learn more about this fascinating topic in our detailed article on the inflammation marker in the blood.

Blood sugar in particular is a critical value: an HbA1c of less than 5.7 percent is considered normal. If your value is higher, this may indicate prediabetes or diabetes that has already developed. A mybody-x home test can conveniently check these crucial values, including HbA1c as well as liver and kidney markers, from the comfort of your home, finally giving you clarity about symptoms such as sleep disorders or weight gain. You can also find comprehensive information about the importance of laboratory values at the ADAC Health Portal. With this knowledge, you can better interpret the results of a comprehensive nutrient or hormone test from mybody-x and take targeted, effective measures for your diet and lifestyle.

The Invisible Controls of Your Well-Being

Do you sometimes feel stressed for no apparent reason, suffer from mood swings, or struggle with skin problems? Often, an invisible imbalance involving hormones and essential nutrients is behind it. You can think of them as the conductors of an orchestra: as soon as even one instrument is out of tune, your body's entire melody falls out of rhythm.

Many of these everyday complaints can be traced back to a deficiency or excess of these powerful substances. The good news is that once you know which levels are crucial, you can take targeted action with a suitable mybody-x test and noticeably improve your quality of life.

Your Top 4 Nutrients for Energy and Balance

Some micronutrients are so fundamental to your daily functioning that a deficiency becomes noticeable immediately. Here are four key players whose blood levels you should definitely keep an eye on.

• Vitamin D – The Sun Hormone for Your Immune System: Although it is known as a vitamin, it acts like a hormone in the body. It not only regulates calcium absorption but is also a crucial factor for your immune defenses and mood. A deficiency is often associated with increased susceptibility to infections and seasonal low moods.

• Vitamin B12 – Fuel for Your Nerves: This vitamin is essential for the formation of red blood cells and the smooth functioning of your nervous system. A deficiency, which is not uncommon with a vegan or vegetarian diet, can cause symptoms such as tingling in the hands and feet, memory problems, and extreme exhaustion.

• Iron (Ferritin) – Your Personal Energy Reserve: Do you constantly feel tired and lacking in energy? Your iron stores could be depleted. Ferritin is the key blood value here, as it indicates your body’s iron reserves. Without enough iron, your body cannot produce sufficient hemoglobin, which restricts oxygen transport and leads to chronic fatigue.

• Magnesium – The Relaxation Mineral: Magnesium is involved in more than 300 enzymatic reactions and plays a central role in your muscles, nerves, and stress management. A deficiency often manifests as muscle cramps, inner restlessness, or sleep problems.

Vitamin D deficiency is quite common, especially in our part of the world. Due to lower levels of sunlight, particularly in autumn and winter, many people cannot meet their needs through their skin alone. A mybody-x nutrient test provides clarity and precisely analyzes these critical levels.

Hormones: The Managers of Mood and Energy

In addition to nutrients, hormones also have a significant impact on how you feel, how well you sleep, and how you cope with daily challenges.

Hormones are your body’s chemical messengers. They regulate everything—from your appetite and libido to your response to stress. Even a slight imbalance can feel like a storm in a teacup and throw your entire system off balance.

Three hormones are especially important for your daily well-being:

1. Cortisol – Your Stress Hormone: When you are stressed, your body releases cortisol to keep you functioning at a high level in the short term. However, if the stress is chronic, your cortisol levels remain elevated. This can lead to sleep problems, weight gain (especially around the abdomen), and exhaustion. If you want to learn more, read our article explaining exactly what cortisol is.

2. TSH – The conductor of your metabolism: As we have already seen, thyroid-stimulating hormone (TSH) controls your thyroid gland. An imbalance can slow down or excessively accelerate your entire energy metabolism and is often the undetected cause of weight problems and low energy.

3. Estrogen and testosterone – The sex hormones: These hormones are responsible for far more than reproduction alone. They influence your skin, bone density, mood, and energy levels. An imbalance can cause menstrual irregularities in women and lack of drive in men.

If you feel that your body has gotten out of sync, targeted hormone and nutrient tests from mybody-x can provide precise insights from the comfort of your home. Instead of groping in the dark, you receive easy-to-understand results and specific recommendations to bring your body’s hidden conductors back into harmony and regain your full vitality.

From knowledge to action: concrete examples from practice

A results report on its own doesn’t change anything. The real strength lies in turning this data into concrete measures for your well-being. That’s exactly where our mybody-x tests come in—with easy-to-understand analyses and personalized recommendations.

Imagine taking a mybody-x nutrient test because you constantly feel tired and unfocused. The result shows a significant deficiency in vitamin B12 and iron (ferritin). Instead of leaving you alone with the numbers, we give you practical tips you can put into action right away.

A blood test from home is more than just diagnostics. It is a tool for empowerment, enabling you to make data-driven decisions about your health and actively take responsibility for your well-being.

For example, your report might advise you to eat more iron-rich foods such as lentils or red meat. At the same time, it could show you which high-quality vitamin B12 supplements may be beneficial for quickly replenishing your stores. This turns an abstract value into a clear plan for your everyday life.

Or take another example: You’re struggling with mood swings and sleep problems and decide to take a mybody-x hormone test. The results show an excessively high cortisol level in the evening—a clear indication of chronic stress.

Our recommendations could address this directly and suggest techniques for reducing stress:

• Establish an evening routine without screen time
• Targeted breathing exercises to calm the nervous system
• Consider taking adaptogenic plants such as ashwagandha

By taking targeted measures based directly on your values, you can achieve noticeable improvements. You move from a vague feeling of discomfort to a clear strategy that sustainably improves your quality of life. If you’d like to learn more about how to easily have your blood values tested, you’ll find more useful information on our blog.

With mybody-x, you turn data into action—for a better sense of well-being.

How to interpret your blood values correctly and take action

At last, you’re holding your mybody-x results report in your hands. A decisive moment! But what exactly do all these numbers and charts tell you about your body? Here you’ll learn how to gain valuable insights from the data and take the right steps for your health.

First things first: Don't panic if a value is occasionally outside the normal range! Don't see it as a problem, but as an important signal from your body—a valuable indication that you should take a closer look. Your mybody-x report is your personal translator for these signals.

From knowledge to action

Your report is much more than just a list of values. It is your starting point for improved well-being. The personalized action recommendations are your most important tool for putting the insights from your blood values into practice in everyday life.

Your blood values show you the “what.” Our recommendations give you the “how.” They translate complex connections into simple, achievable steps.

Imagine this: Your mybody-x nutrient test shows a low ferritin level—so your iron stores are quite depleted. This might explain why you constantly feel tired and lack energy. Your personalized recommendations might then look like this:

• Adjust your diet: Specifically include iron-rich foods such as lentils, oats, or lean beef in your meal plan.
• Combine smartly: Eat vitamin C-rich foods (e.g. bell peppers or oranges) together with iron-rich meals to improve absorption.
• Targeted replenishment: Consider taking a high-quality iron supplement to replenish your stores.

Or take another example: Your mybody-x hormone test shows an elevated TSH level. This is a typical sign of an underactive thyroid, which is often behind unexplained weight gain and low energy. In this case, the recommendations could aim to support your thyroid with nutrients such as iodine and selenium, along with targeted stress management.

The entire process, from collecting your sample to receiving your completed results, is completely straightforward.

This graphic shows you at a glance how simple the process is: collect your sample, send it in, and access your personalized results in the dashboard.

When you should consult a doctor

mybody-x home tests are a powerful tool for taking responsibility for your health and preventing illness. You gain clarity and can take many things into your own hands. Sometimes, however, the next logical step is to talk to your doctor.

Your mybody-x report is the perfect foundation for this. Instead of going to the doctor with unclear symptoms, you now have well-founded, measurable data at hand. This enables a much more focused conversation on equal terms.

Seeing a doctor is particularly advisable if:

• Values deviate significantly from the normal range and indicate a possible illness (e.g. severely elevated liver values or a very high HbA1c level).
• Even if you have followed the recommendations, you do not notice any improvement in your symptoms.
• You are already taking medication and would like to discuss whether an adjustment is necessary.

Use your results as a starting point. Together with your doctor, develop the best strategy for your long-term health and turn knowledge into real change.

Your questions, our answers: Everything you need to know about blood values & at-home tests

Blood tests at home? Naturally, they raise some questions. That’s a good thing, because it shows that you take your health seriously. We’ve collected the most frequently asked questions for you and answer them here—without any medical jargon, we promise.

How often should I actually have my blood values checked?

As a rule of thumb for healthy adults without acute symptoms, a check-up every one to two years is a good basis for keeping track of everything.

Above all, listen to your body! If you constantly feel tired, your weight fluctuates for no apparent reason, or you suspect hormonal changes, don’t wait. A targeted hormone or nutrient test from mybody-x can quickly provide the clarity you need. If you already have a known condition or take medication, your doctor will discuss the appropriate intervals with you anyway.

Can what I eat temporarily distort my results?

Absolutely, and that is an important point. Certain values, especially blood sugar and blood lipids (triglycerides), react almost immediately to your last meal. That is precisely why it is so important for many analyses that you come to the sample collection fasting.

Don’t worry: long-term values such as HbA1c (essentially your blood sugar memory) or vitamin and mineral stores are not affected by this. The instructions for the mybody-x tests always explain exactly—and in a very easy-to-understand way—what you need to keep in mind before collecting your sample.

Are at-home tests really as accurate as tests at the doctor’s office?

Here, we can answer with a clear yes—and dispel a widespread myth. The reliability is identical. mybody-x sends your sample to exactly the same ISO-certified German specialist laboratories that doctors’ practices and clinics also work with.

Your sample undergoes the exact same strict quality analyses there. The only difference? The sample collection. You can do that calmly and easily from home. The result is just as precise and reliable.
