Women's Hormone

Your key hormones and thyroid, with core blood work, in one draw.

Estradiol, FSH, LH, prolactin, total and free testosterone, SHBG, DHEA sulfate, TSH and free T4, plus a complete blood count and a comprehensive metabolic panel. Hormone levels change across the menstrual cycle, so the day you test matters. Estradiol is measured by a standard immunoassay, which is less precise at low levels; where offered, you can switch to the sensitive LC/MS method, which is designed for low levels. Progesterone is available as an add-on because it is usually drawn at a different point in the cycle.

Blood is drawn at a Quest Diagnostics patient service center. Prices depend on the laboratory and state. Enter your ZIP code to see the laboratories near you and your price.

• Complete blood count (CBC): Red cells, white cells with a breakdown by type, and platelets, plus hemoglobin, hematocrit and red-cell size.
• Comprehensive metabolic panel (CMP): Glucose, sodium, potassium, chloride, carbon dioxide, calcium, the kidney tests BUN, creatinine and eGFR, total protein, albumin, bilirubin and the liver enzymes ALP, ALT and AST.
• TSH: Thyroid-stimulating hormone, the pituitary hormone that signals the thyroid.
• Free T4: Free (unbound) thyroxine, the main hormone the thyroid releases.
• Estradiol (standard): Estradiol, a form of estrogen, measured by a standard immunoassay.
• FSH: Follicle-stimulating hormone, a pituitary hormone that signals the ovaries or testes.
• LH: Luteinizing hormone, a pituitary hormone that signals the ovaries or testes.
• Prolactin: Prolactin, a hormone made by the pituitary gland.
• Testosterone, total and free: Total testosterone measured by mass spectrometry, and free (unbound) testosterone measured by equilibrium dialysis.
• SHBG: Sex hormone-binding globulin, the protein that carries testosterone and estradiol in the blood.
• DHEA sulfate: DHEA sulfate, a hormone made mainly by the adrenal glands.

Tests you can add

• Progesterone: Progesterone, a hormone made mainly by the ovaries, with smaller amounts from the adrenal glands.
• TPO antibodies: Antibodies to thyroid peroxidase, an enzyme in the thyroid gland.
• Free T3: Free (unbound) triiodothyronine, the active form of thyroid hormone.
• Cortisol, morning: Cortisol, a hormone made by the adrenal glands, in a sample drawn between 7 and 9 a.m.
• Ferritin: Ferritin, the body's iron-storage protein.

Before your draw

Fasting required.

Fast for 9 to 12 hours before your draw; water is fine. Book a morning appointment, ideally before 10 a.m., for the testosterone test. If you have periods, FSH, LH and estradiol are commonly drawn on cycle days 2 to 5. Record the first day of your last period. Note any hormonal birth control or hormone therapy and when you last took it, and whether you are breastfeeding. If you take insulin or other diabetes medicine, ask your clinician how to take it while you fast. Don't stop your usual medicines unless your clinician tells you to. If you take biotin (vitamin B7), including in hair, skin and nail supplements or multivitamins, have your blood drawn at least 8 hours after a usual dose, or at least 72 hours after a high dose. If biotin was prescribed, ask your clinician before stopping it.
