Start with your health question, not a test count
Fatigue, poor sleep, weight changes, acne or irregular periods can have many possible causes. Note when symptoms began, how often they occur and any medicines or hormones you use. This gives more context when considering tests.
If symptoms persist or affect daily life, ask a clinician whether hormone testing or another assessment is appropriate. Lab results should be interpreted alongside your health history and other findings.
Common groups of tests
This table explains test names found in X-ZELL service information. It does not recommend that everyone take every test.
| Area assessed | Example tests | Context to consider |
|---|---|---|
| Thyroid | TSH, Free T4, Free T3 | A clinician considers further tests based on symptoms and prior results. |
| Sex hormones | Total Testosterone, Estradiol (E2), SHBG | The reason for testing and individual context affect interpretation. |
| Menstrual cycle | LH, FSH, Progesterone, Prolactin | For some tests, the collection day within the cycle matters. |
| Adrenal glands | Cortisol, DHEA-S | Collection time matters, particularly for cortisol. |
| Glucose and metabolism | Insulin (Fasting), HbA1c | HbA1c reflects average blood glucose; it is not a hormone. |
Choose a panel or individual tests?
Panels
Panels group predefined tests by topic. Read the complete list first to see whether it addresses your question.
Individual tests
Useful when following up a specific value for a clear reason. Check the test name, preparation and whether other results are needed for interpretation.
Building a list on the website is not a diagnostic tool. Similar names can measure different things, such as Total Testosterone and Bioavailable Testosterone. HbA1c and Insulin also provide different information.
Preparation depends on the actual tests
Not every hormone test requires fasting, and not every sample can be collected at any time. If you take several tests together, confirm preparation for each one with the provider before your visit.
- Cortisol: Levels vary during the day, so collection time affects interpretation.
- Insulin (Fasting): Confirm the fasting period with the provider and disclose your medicines.
- HbA1c: This test alone does not require fasting, but accompanying tests may.
- Progesterone: Levels change across the menstrual cycle; note the first day of your last period.
Interpret results in context, not from one number
Consider the reported value, units, that lab's reference range, collection time, symptoms, medicines and earlier results. A value outside the range does not always mean disease; a value inside it does not guarantee good health.
If a result is abnormal or symptoms persist, discuss it with a qualified professional rather than diagnosing yourself or changing medication.
Frequently asked questions
Do acne or irregular periods mean PCOS?
Symptoms or a single panel cannot establish PCOS. Assessment considers menstrual history, evidence of androgen excess and other possible causes under clinical criteria.
Can AMH tell whether you will become pregnant?
AMH provides information about ovarian reserve, but one result cannot accurately predict an individual's chance of pregnancy.
Does a result within range mean there is no problem?
Not always. If symptoms continue, the provider may assess other information or consider more testing. Reference ranges and methods can differ between labs.
