Fertility
Your fertility timeline is yours to understand.
Whether you're planning now or planning later — knowledge is power.
This panel measures ovarian reserve, hormone balance, thyroid function, and iron status — the key factors that determine fertility readiness, regardless of your timeline.
Symptoms to watch for
What we test
17-Hydroxyprogesterone
Measures an adrenal hormone precursor to cortisol and androgens. Elevated levels in women may indicate congenital adrenal hyperplasia (CAH), a treatable cause of infertility and excess androgens.
Androstenedione
Measures an androgen precursor hormone produced by the ovaries and adrenal glands. Elevated levels in women suggest PCOS or adrenal disorders contributing to acne, hair growth, and irregular cycles.
Estradiol, Ultrasensitive, LC/MS
Measures estradiol at very low levels using the most precise method. Essential for monitoring women in menopause, on anti-estrogen therapy, or evaluating subtle hormonal changes affecting fertility.
Ferritin
Measures stored iron reserves in the body. The first marker to drop in iron deficiency, essential for women because low ferritin causes fatigue, hair loss, and restless legs even before anemia develops.
hCG, Total, Quantitative
Measures the pregnancy hormone with exact numerical values. Used to confirm early pregnancy, monitor pregnancy progression, and detect ectopic pregnancy or miscarriage risk in women.
Anti-Mullerian Hormone (AMH), Female
Measures a hormone reflecting ovarian reserve (remaining egg supply). The best single test for evaluating fertility potential in women and predicting response to IVF stimulation.
Progesterone, Lc/Ms
Measures progesterone, critical for regulating menstrual cycles and sustaining pregnancy. Low levels in women can cause irregular periods, difficulty conceiving, and increased miscarriage risk.
Prolactin
Measures prolactin, the hormone responsible for breast milk production. Elevated levels in non-pregnant women can cause missed periods, infertility, and may indicate a pituitary gland issue.
TSH
Measures thyroid-stimulating hormone, the primary thyroid screening test. Women are 5-8 times more likely than men to develop thyroid disease, making TSH essential for detecting hypo- and hyperthyroidism.
TIBC (Total Iron Binding Capacity)
Measures the blood's capacity to bind and transport iron. Elevated TIBC indicates iron deficiency, common in women with heavy periods, helping distinguish between types of anemia.
Iron, Total
Measures total iron in the blood used for oxygen transport. Critical for women because menstruation causes regular iron loss, and deficiency leads to fatigue, weakness, and impaired fertility.
Iron Saturation %
Calculates the percentage of iron-binding sites that are filled. Low saturation confirms iron deficiency in women, while high saturation may indicate iron overload or hemochromatosis.
Who should consider this panel?
Women considering pregnancy in the next 1-5 years
Anyone with irregular, absent, or very heavy periods
Women with PCOS or suspected PCOS
Those who've experienced miscarriage or difficulty conceiving
Women considering egg freezing who want to assess ovarian reserve
