Female hormone levels are most commonly tested through a simple blood draw from a vein in your arm. The sample is sent to a lab, and results typically come back within a few days. Depending on what your provider is investigating, you may need the blood drawn on a specific day of your menstrual cycle, because hormone levels shift dramatically from one week to the next.
The Standard Blood Panel
A female hormone blood panel usually measures some combination of the following hormones, depending on the reason for testing:
- Estradiol, the primary form of estrogen, which fluctuates throughout your cycle. Normal levels range from 20 to 350 pg/mL during the first half of your cycle, peak at 150 to 750 pg/mL around ovulation, and settle between 30 and 450 pg/mL in the second half.
- Follicle-stimulating hormone (FSH), which tells your ovaries to grow follicles and prepare eggs for release.
- Luteinizing hormone (LH), which triggers ovulation and works alongside FSH to regulate your cycle.
- Progesterone, which rises after ovulation and supports early pregnancy.
- Testosterone, which women produce in smaller amounts and which plays a role in energy, libido, and conditions like PCOS.
Your provider may also add thyroid-stimulating hormone (TSH) to the panel, since thyroid problems can mimic or worsen hormonal symptoms like irregular periods, fatigue, and weight changes.
Why Timing Matters
Hormone levels aren’t static. They change day to day across your menstrual cycle, which means drawing blood on the wrong day can produce misleading results. For basic fertility testing, FSH and estradiol are measured on day 3 of your cycle (counting the first day of your period as day 1). This early-cycle snapshot shows your baseline levels before the ovaries ramp up for ovulation. FSH levels at this point reflect how hard your body has to work to stimulate egg development, so an unusually high number can signal declining ovarian function.
Progesterone testing follows a different schedule. It’s typically drawn around day 21 of a 28-day cycle, about a week after ovulation should have occurred. A level in the range of 2 to 25 ng/mL during this luteal phase suggests that ovulation happened. If progesterone stays low, it may mean you didn’t ovulate that cycle.
Testing for Fertility and Ovarian Reserve
If you’re trying to conceive or considering egg freezing, your provider will likely order an anti-Müllerian hormone (AMH) test. AMH reflects the number of egg-containing follicles remaining in your ovaries, giving a snapshot of your ovarian reserve. Unlike most other hormone tests, AMH stays relatively stable throughout your cycle, so it can be drawn on any day.
AMH levels decline naturally with age. Median levels are roughly 26.6 pmol/L for women aged 20 to 25, dropping to about 13.7 pmol/L by ages 36 to 40, and falling sharply to around 0.7 pmol/L by the late 40s. Your provider will interpret your result in the context of your age rather than against a single cutoff number. AMH is widely used in IVF planning to predict how your ovaries will respond to stimulation medications.
Screening for PCOS
When polycystic ovary syndrome (PCOS) is suspected, testosterone is the key hormone to measure. Total testosterone is generally considered more reliable than free testosterone for this purpose, since the lab methods for measuring free testosterone can be inconsistent. Most women with PCOS have testosterone levels at or below 150 ng/dL. If testosterone comes back above 200 ng/dL, that’s high enough to raise concern about an ovarian or adrenal tumor rather than PCOS alone.
A PCOS workup also often includes LH (which tends to run high relative to FSH) and a fasting glucose-to-insulin ratio. If any combination of elevated LH, a low glucose-to-insulin ratio (below 4.5), or elevated testosterone is present, and other conditions have been ruled out, the diagnosis is typically confirmed.
Confirming Perimenopause or Menopause
Menopause is usually diagnosed based on symptoms and the absence of periods for 12 consecutive months, but blood tests can help clarify what’s happening during the transition. Elevated FSH levels above 25 mIU/mL, combined with gaps of 60 days or more between periods, are the consensus criteria for late perimenopause. FSH rises because the ovaries are producing less estrogen, and the brain keeps sending stronger signals trying to stimulate them. A single elevated FSH reading isn’t definitive on its own, since levels bounce around during perimenopause. Your provider may repeat the test or combine it with estradiol levels to get a clearer picture.
Saliva and Urine Testing
Blood draws are the clinical standard, but saliva and dried urine tests exist as alternatives. Saliva testing measures the “free” or unbound fraction of a hormone, which is the portion actively available to your tissues. For cortisol (the stress hormone), saliva can sometimes be more informative than blood, particularly if you take oral contraceptives. Birth control pills raise the level of a protein that binds cortisol in your bloodstream, which can make blood cortisol levels appear falsely normal when they’re actually low. Salivary cortisol sidesteps this problem because it reflects only the unbound hormone.
That said, saliva testing has practical limitations. How the sample is collected matters: cotton swabs can overestimate cortisol levels, while passive drooling into a container tends to be more accurate. Sample handling and storage can also affect results, and the correlation between saliva and blood measurements weakens under certain testing conditions. Research has not consistently supported saliva as a reliable replacement for blood in all situations.
Dried urine testing takes a different approach. You collect urine samples on filter paper at multiple points throughout the day. The main advantage is that urine captures hormone metabolites, the breakdown products your body creates as it processes hormones. Free cortisol in blood or saliva represents less than 5% of total cortisol production. The other 95% is cleared through metabolites that only show up in urine. This can give a more complete picture of how your body produces and processes cortisol over a full day. Dried urine panels are sometimes marketed for comprehensive hormone profiling, though they’re used more often in integrative and functional medicine settings than in conventional practice.
What to Expect During the Test
For a blood test, you’ll have a standard venous draw, usually from the inside of your elbow. The process takes a few minutes, and you may be asked to fast beforehand if glucose or insulin is being measured alongside your hormones. Some providers request that you come in first thing in the morning, since certain hormones like cortisol follow a daily rhythm and peak shortly after waking.
Results typically include your measured value alongside a reference range. Keep in mind that reference ranges vary between labs, and your results need to be interpreted alongside your symptoms, age, cycle day, and any medications you’re taking. A number that looks “normal” on paper can still be clinically meaningful if it doesn’t match what’s expected for your situation.
