Description of blood Analysis: 

 Androstenedione is a steroid hormone produced by the adrenal glands and the gonads (ovaries in women, testes in men). It serves as a major “precursor” molecule, meaning the body converts it into more potent hormones like testosterone and estrone. While it has relatively weak androgenic effects on its own, its overproduction can lead to significant symptoms of androgen excess, particularly in women and children.

What Does the Test Represent?

• Goal: To evaluate the production of male sex hormones and identify the source of hormonal imbalances.
• Main Application: Diagnosing the causes of virilization (excessive hair growth, voice deepening), assessing Polycystic Ovary Syndrome (PCOS), and monitoring treatment for Congenital Adrenal Hyperplasia (CAH).
• Method: Chemiluminescent immunoassay (CLIA) or Liquid Chromatography-Mass Spectrometry (LC-MS/MS).

Collection Recommendations (General)

• Timing: In women of reproductive age, the sample should ideally be collected one week before or after the menstrual period (though often done during the early follicular phase, Day 2–5, for a baseline). Due to diurnal variation, morning collection is preferred.
• Hygiene: Standard venipuncture procedure.
• Material: Venous blood (serum).
• Specific Rules: Always record the day of the menstrual cycle, as reference ranges are cycle-dependent.

What Can Affect the Results?

• Factors Altering Levels: Intense physical exercise, severe emotional stress, and pregnancy. Levels naturally fluctuate during the menstrual cycle, peaking mid-cycle.
• Medications: Hormonal contraceptives (birth control), glucocorticoids (like prednisone), and testosterone-related supplements can suppress or artificially inflate levels.

When to Take the Test?

• Recommendations: If you experience hirsutism (excessive body/facial hair), persistent acne that doesn’t respond to treatment, irregular menstrual periods, or signs of premature puberty in children.
• Preparation: Fasting for 8–12 hours is generally recommended. Avoid biotin-containing supplements for 48 hours before the test.

How to Interpret the Results? 

The interpretation of Androstenedione levels is strictly a clinical analytical task for a physician. Elevated levels often suggest overactivity of the adrenal glands or ovaries. In the context of PCOS, androstenedione is frequently elevated along with testosterone. Very high levels may prompt a search for a hormone-secreting tumor. Only a specialist can “fine-tune” the diagnosis by evaluating the ratio of androstenedione to other androgens like DHEA-S.

Possible Further Investigations

• Total and Free Testosterone: To measure the final, active products of androgen metabolism.
• DHEA-S: To specifically check the contribution of the adrenal glands.
• 17-OH Progesterone: To rule out or monitor Congenital Adrenal Hyperplasia.
• Pelvic Ultrasound: To check for polycystic ovaries or other structural abnormalities.

When Does the Next Step Make Sense?

 If androstenedione levels are high, the next step involves determining whether the excess is coming from the ovaries or the adrenals. Managing this hormone is essential for improving skin health, regulating the menstrual cycle, and restoring overall hormonal equilibrium.

👉 If necessary, you can discuss the analysis results with a specialist such as an endocrinologist (Doctors – TAMC), gynecologist (Doctors – TAMC), or urologist (Doctors – TAMC).
