Scan4Health’s Androstenedione (A4) Test provides a precise assessment of androstenedione levels, a key steroid hormone produced by the adrenal glands and gonads. As a precursor to testosterone and estrogen, androstenedione is vital for diagnosing endocrine disorders and informing effective treatment plans.

• Routine Preparation: No fasting is required. Continue regular meals and hydration unless your doctor instructs otherwise.
• Medication Guidance: Share details of all medicines, supplements, or hormone therapies with your doctor—especially steroids, birth control pills, and fertility agents.
• Timing: For women, the timing may matter (due to menstrual cycles); clarify with the lab if your doctor gives specific instructions on the best collection window.
• Symptoms/History: Document any issues such as excess facial or body hair, unexplained acne, changes in menstrual cycles, infertility, or symptoms linked to early puberty.
• Procedure Comfort: Wear comfortable clothing to access an arm vein for blood collection easily.

This test quantifies the concentration of androstenedione in your bloodstream—a hormone integral to the balance of sex hormones in both men and women. Doctors order the A4 test for patients suffering from unexplained hormonal symptoms, suspected adrenal or ovarian disorders, or as part of broader screening when dealing with fertility issues, abnormal hair growth, or early/late puberty. Typical indications for the A4 test include evaluation of possible polycystic ovary syndrome (PCOS), congenital adrenal hyperplasia (CAH), adrenal or ovarian tumors, and sometimes suspected anabolic steroid abuse in athletes. For men, high levels may suggest testicular or adrenal tumors; for women, elevations are most commonly linked to PCOS, CAH, or androgen-secreting tumors. The procedure involves a routine blood draw from your arm. The sample is processed using state-of-the-art analytical techniques to determine your hormone level. Your doctor may order additional complementary tests—such as testosterone, estrogen, DHEAS, LH, FSH, and SHBG—to get a more complete picture of your hormone balance. Results within normal ranges suggest healthy adrenal and gonadal function. Elevated levels point toward excess androgen production, which may underlie symptoms like hirsutism, severe acne, menstrual irregularities, or infertility. Low levels, although less common, can be linked to adrenal insufficiency, pituitary gland disorders, or other hormonal imbalances.
