Core markers
Hormones People Commonly Ask About
Hormone levels vary by age, menstrual-cycle phase, pregnancy status, medications, menopause stage, and test method. Lab ranges should be interpreted with clinical context.
Estrogens
Estrogens are a group of hormones involved in puberty, menstrual cycles, pregnancy, menopause, bone health, and other body systems. An estrogen test may measure estrogen levels in blood, urine, or saliva, depending on the clinical question and lab method.
Progesterone
Progesterone is involved in menstrual-cycle regulation and pregnancy. Progesterone or related progestins are also used medically in specific contexts, including some hormone-therapy regimens, but treatment choices depend on personal medical history.
FSH and LH
Follicle-stimulating hormone and luteinizing hormone are pituitary signals. Clinicians may use them when evaluating menstrual irregularity, ovarian function, fertility questions, or menopause-related questions.
Prolactin and thyroid markers
Cycle changes, fertility concerns, fatigue, mood symptoms, and libido changes are not specific to estrogen or progesterone. Prolactin, thyroid, medication history, stress, weight change, sleep, and other factors may matter.
Testing hygiene
How To Make Lab Conversations Less Messy
Record timing
Write down the first day of the last menstrual period, cycle day of the blood draw, pregnancy status if relevant, menopause status, and time of collection.
List medications
Bring a complete medication and supplement list, including hormonal contraception, fertility medications, menopause therapies, steroids, thyroid medication, and psychiatric medications.
Separate symptoms from conclusions
Track symptoms plainly: bleeding pattern, hot flashes, night sweats, sleep, mood, libido, pain, acne, hair changes, weight change, and fertility concerns. Do not jump straight to a hormone label.
Use clinician interpretation
Reference ranges differ by lab and method. A result that looks high or low online may not answer the actual medical question without history, exam, and repeat testing when appropriate.
