Bioidential Hormone Testing for Women in California

Bioidentical hormone testing for women measures levels of certain hormones in the blood. It is ordered to evaluate symptoms that may relate to hormone changes, such as those around menopause, or to check hormone levels during or after hormone therapy. The term 'bioidentical' describes hormones that are chemically identical to those the body makes; the test itself measures hormone levels in your blood.

What it measures

Estradiol — A form of estrogen; helps assess ovarian function and menopause-related changes.
Progesterone — A hormone that rises after ovulation; used to evaluate the menstrual cycle.
Testosterone — Present in women in small amounts; affects energy, mood, and libido.
Follicle-stimulating hormone (FSH) — Helps show whether the ovaries are still active or nearing menopause.
Luteinizing hormone (LH) — Works with FSH to regulate the menstrual cycle and ovulation.
Sex hormone-binding globulin (SHBG) — A protein that binds hormones and affects how much is free to act.

Who it is for

A clinician may order this test for women with symptoms such as hot flashes, irregular periods, mood changes, or low libido, or to monitor hormone therapy. It is not a routine screening test for all women.

Preparation

Preparation depends on which hormones are measured; some tests require a specific day of your cycle or a morning draw. Fasting is often not required, but follow the instructions given by your clinician or lab.

Results and what they mean

Results are reported as number ranges for each hormone, and normal ranges vary by lab, age, cycle phase, and whether you use hormones. A clinician interprets the results alongside your symptoms and history; results alone do not diagnose a condition. This is general information, not medical advice.

Frequently asked questions

Do I need to fast before this test?

Usually no. If fasting is needed, your clinician or lab will tell you in advance.

When in my cycle should I test?

Timing may matter. Your clinician may ask you to test on a specific cycle day or at a certain time of day.

Is saliva or blood better for hormone testing?

Blood testing is commonly used and well studied. Ask your clinician which sample type is appropriate for your situation.

Can I order this test myself?

Some labs offer direct testing, but results are best reviewed with a clinician who knows your history.
