Hormone blood test measuring Androstenedione to investigate PCOS and adrenal disorders.
A hormone panel measures the chemical messengers that regulate virtually every function in your body — from energy and mood to metabolism, sleep, reproduction, and muscle growth. Hormones fluctuate with age, stress, sleep quality, and lifestyle, and imbalances can cause symptoms that are often attributed to "just getting older." Common markers include testosterone and estradiol (sex hormones), cortisol (the stress hormone), DHEA-S (an adrenal precursor), thyroid hormones, and gonadotropins like FSH and LH that regulate reproductive function. Men typically see testosterone decline after 30, while women experience significant hormonal shifts during perimenopause and menopause. Testing provides objective data to distinguish hormonal issues from other causes.
Key Details
Who Is This For?
Men over 30 experiencing low energy, reduced libido, difficulty building muscle, or mood changes. Women with irregular periods, fertility concerns, or perimenopausal symptoms. Anyone experiencing unexplained fatigue, weight gain, sleep disruption, or mood swings. Athletes interested in optimizing recovery and performance through hormonal insights.
What's Included
Preparation Required
Fasting for 10–12 hours before your appointment is recommended for accurate results (water is fine). Avoid alcohol for 24 hours and intense exercise for 12 hours before the blood draw. Morning appointments are ideal for consistent hormone and glucose readings. The blood draw typically takes 5–10 minutes.
Biomarkers Tested
5Androstenedione is a steroid hormone and a precursor to testosterone and estrogen. Abnormal levels can indicate adrenal or reproductive 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 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.
