Which at-home test kits sensibly combine DNA, blood, and gut analyses?

A single test kit that performs DNA, blood, and gut analyses from one sample combined, are not available at mybody®—the sample types are too differently (saliva, blood drop, stool sample). A sensible can instead be combined are three specialized individual tests that mybody® groups together under the Longevity category: the Longevity ALL IN ONE DNA Test, Nutrient | VitalCheck Complete blood test and the gut flora MICROBIOME Test Complete.

The reason for this three-part combination: Each test answers a different question. DNA shows your long-term genetic predisposition, the blood test shows your current nutrient and health status, and the the gut test shows the state of your microbiome balance. Together, they provide a much more complete picture than any test alone.

Why 3 different types of tests? Each answers a different question

Why is a single test often not enough?

A DNA test reliably shows your genetic predisposition—but it does not tell you whether you currently actually have whether you have a vitamin D deficiency or whether your gut flora is currently out of becomes unbalanced. Your genes remain the same throughout your life, your nutrient status and microbiome, on the other hand, are constantly changing your nutrient status and microbiome, on the other hand, are constantly changing due to diet, stress, medication, or illness.

A blood test, in turn, shows your current status, but it explains but not why certain patterns occur in your body—this is where the genetic classification from the DNA test. And your gut microbiome in turn affects how well your body absorbs nutrients in the first place, which can directly affect your blood values. Only when viewed together all three levels create a coherent overall picture instead of individual Puzzle pieces.

The 3 tests compared

1. Longevity | ALL IN ONE DNA Test (Saliva)

Analyzes more than 170 gene variations related to metabolism, nutrition, fitness, skin, and aging processes—the genetic foundation of your longevity strategy, serving as a stable reference for all your future tests. Price: €369 (instead of €629).

2. Nutrient | VitalCheck Complete (blood drops)

Measures your current status of vitamins, minerals, and other health markers using capillary blood drops—your changeable current state as a useful complement to your unchanging genetic predisposition. Price: €169 (instead of €199).

3. Gut microbiome | MIKROBIOM Test Complete (stool sample)

Analyzes the composition of your gut microbiome, possible dysbioses, and inflammatory markers in stool—your microbiome as a third, complementary level that influences how well you can absorb nutrients at all. Price: €189 (instead of €219). Bestseller in this category.

What is the best order in which to combine the tests?

There is no mandatory order—the tests do not affect one another, so you can take them at the same time or perform one after another. However, it makes sense to start with the DNA test because your start, since your genetic predisposition never changes and gives you a provides a stable foundation on which you can base your other results can.

you can take the blood test and gut test in parallel or a few carry out over several weeks. Since your nutrient status and microbiome can Unlike your genes, which can change over time, it is it makes sense to repeat these two tests as needed—for example, after major dietary changes or once a year, while the DNA test only needs to be taken once.

What are the benefits of combining the tests compared with an individual test?

The combination primarily helps you identify the causes of symptoms distinguish between them. If you feel constantly tired, for example, this could be due to a genetically determined weakness in vitamin B12 absorption (DNA), for example. To an actually low B12 level at the moment (blood) or a disturbed gut microbiome, which makes absorption even more difficult (gut). Only with all three perspectives, you see the complete picture instead of just of a snapshot.

The combination is also valuable for your nutrition strategy: The DNA test shows you your basic predisposition, while the blood test shows your current needs, while the gut test shows how well your body can absorb the recommended can absorb nutrients at all. This allows recommendations to be targeted coordinate them instead of having them stand isolated side by side.

Typical use cases for the combination

A classic example is chronic fatigue without a clear cause: The DNA test shows whether there is a genetically reduced ability to absorb vitamin B12 or D3 intake is present, and the blood test confirms whether it is actually currently whether a deficiency exists, and the gut test shows whether an impaired gut flora nutrient absorption is further impaired. Only all three results together provide a coherent explanation.

A second example is the general longevity or anti-aging strategy: Aging processes are influenced by an interplay of genetics, current nutrient status, and gut health. Chronic inflammation, oxidative stress, and an impaired gut flora are considered key drivers of accelerated aging. The The three-test combination reveals which lever—genes, nutrients or microbiome—the greatest leverage lies with you personally.

You also benefit from this when optimizing your diet and weight all three perspectives: The DNA test shows your fundamental metabolic predisposition, the blood test your current status regarding blood sugar, blood lipids, or inflammation markers, while the gut test shows how well whether your microbiome can effectively implement the recommended dietary changes can support.

What influences your genes and microbiome as you age?

Your genes influence, among other things, how resilient your cells are against oxidative stress is, how well repair mechanisms in your cells function and how pronounced your tendency toward inflammation is are. These genetic pathways remain stable throughout life and can be be measured just once with a DNA test.

Your gut microbiome, on the other hand, changes continuously and affects your immune system, inflammation levels, and nutrient absorption. An unfavorable composition is associated, among other things, with chronic inflammation and metabolic disorders. Because your microbiome unlike your genes can change, regular monitoring is worthwhile here regular monitoring, while your DNA profile serves as a stable the reference range remains unchanged.

Can you buy the tests individually, or is there a savings package?

All three tests can be ordered individually—you are not required to buy all three together immediately. There is no fixed “3-in-1 mybody® currently does not offer a “combination package” with all three types of tests a standard product, but occasional promotions and discount codes are available (e.g., through the CareClub or seasonal offers), which also apply to use several tests ordered at the same time.

If you start with a limited budget, it makes sense to begin with the start with the test that best matches your most urgent concern— for example, the blood test for suspected acute deficiencies or the gut test for digestive complaints—and add the other tests later, instead of giving up on the combination altogether for cost reasons. This is how you build your your complete health profile step by step, instead of having to finance it all at once, while remaining flexible at any time decide which level is most relevant to you next.
