Criteria for choosing the right hormone level test
Before booking or buying a hormone test, it’s worth taking stock. Which hormones are you actually interested in? This isn’t a trivial question, because the human body produces dozens of hormones, and not every test measures them all equally well.
The most important hormones at a glance:
- Testosterone (for energy, muscle mass, libido in men and women)
- Cortisol (stress hormone, daily rhythm, sleep quality)
- Thyroid hormones TSH, fT3, fT4 (metabolism, weight, mood)
- Estrogen and progesterone (cycle health, menopause, fertility)
- FSH and LH (hormone axis, fertility, menopause)
- DHEA and prolactin (vitality, stress axis, breastfeeding)
Each of these hormones has its own rhythm. Cortisol, for example, is at its highest in the morning and declines throughout the day. Testosterone also peaks in the morning. This means timing determines how meaningful each measurement is. Ideally, you should test in the morning between 7 and 10 a.m., while fasting and under conditions that are as consistent as possible.
Another important point is the number of measurements. A single value says little. Hormones fluctuate daily, weekly, and with the menstrual cycle. To identify trends, you need at least two or three measurements over a defined period. This is especially true for women, whose hormone levels change significantly over the course of the month.
Pro tip: Before each measurement, note your sleep, stress levels, and cycle day. This context makes your results truly interpretable.
Self-tests from drugstores or online may seem convenient, but they have a structural weakness: they provide numbers without context. Measurement uncertainty in hormone analyses is a known problem that must be carefully controlled even in clinical labs. Without medical advice, you risk misinterpreting the results.
Your goal is also crucial. Do you want to optimize your diet, understand your stress resilience, or investigate a specific concern? The clearer your goal, the more precisely you can choose the right test. At-home hormone tests are much more precise today than they were five years ago, but they don’t replace knowing what you actually want to measure.
Blood tests: The gold standard for hormone measurement
When doctors and endocrinologists talk about hormone tests, they usually mean blood tests. And for good reason. Blood tests are considered the standard for total hormones, including thyroid hormones, FSH, LH, and prolactin.
Benefits of blood tests at a glance:
- High precision through standardized laboratory procedures
- Possible to measure total hormones and bound fractions
- Scientifically recognized and established in medicine
- Suitable for trend analysis across multiple measurements
- Broad range of measurable hormones
The procedure is standardized: fasting, in the morning, with a venous blood draw. Modern labs use methods such as LC-MS/MS (liquid chromatography coupled with mass spectrometry) or ELISA (enzyme-linked immunosorbent assay). The comparison between LC-MS/MS and ELISA shows that LC-MS/MS measures hormone concentrations much more precisely at low levels, which is especially relevant for women and children.
Important: A blood test always measures total hormone in the blood, meaning both the bound and free fractions. However, the free fraction is biologically active and actually enters the cells. For some questions, this is a crucial distinction.
The limitations of blood tests are clear: You need a doctor's appointment or a lab that accepts at-home submissions. A single blood test is often not very informative for cortisol because it only provides a snapshot, not the daily pattern. And for certain free steroid hormones, a saliva test is the better choice.
Pro tip: When getting a blood test, always have SHBG (sex hormone-binding globulin) measured as well. This protein affects how much free testosterone or estrogen is actually available and can significantly change how your results are interpreted.
For anyone who wants to have their hormone levels professionally tested, a blood test is the most reliable starting point. Anyone who wants to test their hormone balance will find the broadest scientific evidence base here.
Saliva tests: The alternative for free hormones and cortisol rhythms
Saliva tests have improved significantly in quality in recent years. They don't measure total hormone, but rather the free, biologically active fraction. This is a clear advantage for certain questions.
Saliva tests are particularly suitable for bioactive hormones and daily cortisol profiles. This means you take a saliva sample in the morning, at noon, in the afternoon, and in the evening, and the lab uses them to create a complete daily profile of your cortisol levels. This simply isn't possible with a single blood test.
Advantages of saliva tests:
- Non-invasive, no blood, no doctor's appointment required
- Ideal for daily cortisol profiles and stress diagnostics
- Measures free, biologically active hormones
- Convenient to do at home
- Well suited for monitoring over weeks and months
Disadvantages of saliva tests:
- Quality depends heavily on the analytical method
- ELISA-based saliva tests are less precise than LC-MS/MS
- Not suitable for all hormones (e.g., thyroid hormones)
- Lack of guidance with self-tests only
| Feature | Blood test | Saliva test |
|---|---|---|
| Measured fraction | Total hormone | Free hormone |
| Invasiveness | Venipuncture | Non-invasive |
| Daily cortisol profile | Not possible | Ideal |
| Precision (LC-MS/MS) | Very high | High |
| Possible at home | Limited | Yes |
Pro tip: When taking a saliva test, make sure the lab uses LC-MS/MS. Modern hormone testing methods clearly show that ELISA-based saliva tests tend to produce errors at low hormone concentrations, which can be clinically relevant.
For women who want to better understand their cycles and hormonal fluctuations, saliva tests are a valuable addition. Find out more in the articles on hormone tests for women and the hormone test for women.
At-home self-tests: opportunities and risks
Self-tests are appealing. They promise quick answers, easy use, and low prices. But what’s really behind them?
The reality is nuanced. Simple strip tests or inexpensive home kits often use immunoassay methods, which were developed for screening, not precise diagnostics. Endocrinologists are often critical of self-tests because measurement accuracy varies widely and false-positive or false-negative results are not uncommon.
What self-tests can do:
- Provide initial guidance if a hormonal disorder is suspected
- Motivate you to take an active approach to your health
- Roughly track trends across multiple measurements
- Convenient and can be done without a doctor’s appointment
What self-tests can’t do:
- Provide clinically valid diagnoses
- Replace medical advice
- Fully assess complex hormonal pathways
- Put results into an individual health context
A study on reliability of home tests shows that variability between different self-test products is considerable. This means two different tests for the same hormone can produce different results for the same person, even when their actual hormone levels haven’t changed.
Pro tip: Don’t use self-tests as a single measurement, but as a tool for tracking changes over time. Three measurements taken four weeks apart will tell you more than a single reading, no matter how precise the device is.
The recommendation: At-home tests are a useful addition for health-conscious people who want to monitor trends. However, they should always be supplemented with a lab analysis before making dietary or lifestyle decisions. Anyone looking for at-home hormone tests should look for ISO-certified laboratory analysis.
An overview comparing common types of hormone tests
Now that we’ve looked at each option individually, here’s a direct comparison. LC-MS/MS delivers the most valid results in both blood and saliva and is now considered the reference method.
| Test method | Analysis method | Purpose | Advantages | Disadvantages |
|---|---|---|---|---|
| Blood test | LC-MS/MS, ELISA | Total hormones, thyroid, FSH, LH | High precision, broad range | Doctor’s visit, invasive |
| Saliva test | LC-MS/MS, ELISA | Daily cortisol profile, free hormones | Non-invasive, can be done at home | Not suitable for all hormones |
| At-home test | Immunoassay | Initial overview, trend monitoring | Affordable, simple | Lower precision, no consultation |
Recommendations based on your goal:
| Goal | Recommended method |
|---|---|
| Check thyroid function | Blood test (TSH, fT3, fT4) |
| Understand the stress axis | Saliva test (daily cortisol profile) |
| Optimize testosterone | Blood test with SHBG measurement |
| Women’s cycle health | Saliva or blood test depending on the phase |
| Initial overview | At-home test as a starting point |
| Long-term trends | Multiple lab analyses over time |
Anyone looking to get their testosterone tested will find that an LC-MS/MS blood test provides the most reliable basis. For cortisol testing, a saliva test is the first choice. And for a general introduction to hormone testing, a combined approach offers the greatest value.
Our take: What really matters in hormone testing
After years of working with health analyses, we’ve made one clear observation: most misunderstandings don’t stem from poor tests, but from a lack of context. A single hormone reading, taken out of context, is almost worthless. It doesn’t tell you whether you feel unwell because your cortisol is too high, or whether your cortisol is too high because you feel unwell.
This may sound obvious, but it is at the heart of the problem. Experts recommend medical interpretation because hormones act within a complex network that cannot be reduced to a single number. Anyone looking to regulate their hormone balance needs trends, context, and guidance, not just test results.
Our recommendation for health-conscious people: Start with a validated lab analysis as a baseline. Use at-home tests to monitor changes between lab measurements. And always interpret your results in the context of sleep, nutrition, stress, and exercise. Hormone diagnostics is not a one-time event, but an ongoing process.

Frequently asked questions about types of hormone tests
When is the best time to test hormone levels?
Timing determines how informative the measurement is: hormone levels should be measured in the morning between 7 and 10 a.m.; for women, some hormones should also be measured on specific days of the menstrual cycle.
How reliable are at-home hormone tests?
At-home tests are often inaccurate and do not replace medical advice, so they should be used only as a rough guide, not as a basis for medical decisions.
Which method is suitable for measuring cortisol?
For measuring the daily cortisol profile, saliva tests using LC-MS/MS are a sensible gold-standard option because they can capture multiple times of day.
What is the difference between blood and saliva tests?
Blood tests measure total hormones and are established for standard diagnostics, while saliva tests capture free hormones and daily rhythms, as modern testing methods show.
How often should hormone levels be tested?
Multiple measurements over a period of time are advisable, as tracking trends is essential for reliably assessing changes and avoiding misleading one-off results.
