Women's Hormone Test Panel — Expanded

Regulates reproductive function in both sexes. In women, FSH stimulates egg development; elevated levels indicate declining ovarian reserve or menopause. In men, FSH stimulates sperm production.

Works with FSH to regulate reproductive function. In women, an LH surge triggers ovulation. In men, LH stimulates testosterone production. Abnormal levels can indicate pituitary or gonadal disorders.

The most potent and prevalent form of estrogen. In women, estradiol regulates the menstrual cycle, fertility, and bone density. In men, it's produced from testosterone and plays roles in bone health and libido. Levels vary significantly with age and menstrual cycle.

A hormone essential for menstrual cycle regulation and pregnancy maintenance. Progesterone rises after ovulation, preparing the uterus for implantation. Low levels can cause irregular periods and difficulty maintaining pregnancy.

The primary male sex hormone, also important in women at lower levels. Testosterone regulates muscle mass, bone density, fat distribution, libido, and mood. Levels decline naturally with age in both sexes.

A hormone produced by the adrenal glands, serving as a precursor to testosterone and estrogen. DHEA peaks in early adulthood and declines steadily with age. It's one of the most studied biomarkers in anti-aging research.

The primary screening test for thyroid function. TSH is produced by the pituitary gland to regulate thyroid hormone production. High TSH indicates an underactive thyroid (hypothyroidism), while low TSH suggests an overactive thyroid (hyperthyroidism).

The unbound, active form of the main thyroid hormone T4. Free T4 directly reflects thyroid gland output and is used alongside TSH to diagnose and monitor thyroid disorders.

The active form of thyroid hormone responsible for regulating metabolism, energy, and body temperature. Free T3 is converted from T4 in tissues and is three to four times more potent than T4.

Antibodies against thyroid peroxidase, an enzyme essential for thyroid hormone production. Positive TPO antibodies indicate autoimmune thyroid disease, most commonly Hashimoto's thyroiditis, even before symptoms or TSH changes appear.

A hormone primarily known for stimulating breast milk production. Elevated prolactin in non-pregnant individuals can indicate pituitary tumors, medication side effects, or hypothyroidism. High levels can suppress reproductive hormones.

A protein that binds and transports sex hormones (testosterone, estrogen) in the blood. High SHBG reduces the amount of free, active hormones available. SHBG increases with age, thyroid hormones, and estrogen; decreases with obesity and insulin resistance.

The primary stress hormone, produced by the adrenal glands. Cortisol regulates metabolism, immune response, blood pressure, and the sleep-wake cycle. Chronically elevated cortisol from stress contributes to weight gain, immune suppression, and metabolic dysfunction.

The sulfated, stable form of DHEA with a long half-life, making it the preferred test for adrenal androgen production. DHEA-S is the most abundant circulating steroid hormone and a key longevity biomarker.

The unbound, biologically active fraction of testosterone (typically 1–3% of total). Free testosterone is the form that can enter cells and exert effects. More clinically relevant than total testosterone for assessing hormonal status.
