This test measures androstenedione hormone levels in your blood 30 minutes after receiving a hormone injection (stimulation) to evaluate how well your adrenal glands are working.

Quick summary

{"Measures androstenedione hormone levels after adrenal gland stimulation","Helps diagnose adrenal gland disorders like congenital adrenal hyperplasia","Involves a blood draw before and 30 minutes after a stimulation injection","The stimulation is typically with ACTH (cosyntropin) or hCG hormone"}

What is this test?

The Androstenedione Stimulation Test is a blood test that measures the level of androstenedione in your serum or plasma. Androstenedione is a hormone produced by your adrenal glands (located on top of your kidneys), as well as in smaller amounts by the ovaries in women and testes in men. This hormone is a precursor to other important hormones like testosterone and estrogen.

How does the test work?

The test involves two blood draws: one before and one 30 minutes after receiving a "challenge" injection. The challenge is typically with adrenocorticotropic hormone (ACTH, also called cosyntropin) or sometimes human chorionic gonadotropin (hCG). This injection stimulates your adrenal glands to produce more hormones. By comparing the before and after levels, doctors can see how well your adrenal glands respond to stimulation and identify any problems with hormone production.

Why is it performed?

This test is primarily used to evaluate adrenal gland function. It helps doctors diagnose conditions that affect hormone production, including congenital adrenal hyperplasia (a genetic disorder affecting adrenal hormone production), adrenal insufficiency (underactive adrenal glands), and certain adrenal tumors. It may also be used to evaluate pubertal disorders or abnormal hair growth in women (hirsutism).

How to prepare

Follow your doctor's instructions about any medications you may need to stop before the test. You may need to fast (not eat or drink) for a certain period before the test. Inform your doctor about all medications, supplements, or herbal remedies you are taking, as some can affect hormone levels. Wear comfortable clothing with sleeves that can be easily rolled up for the blood draw.

What to expect during the test

A healthcare professional will first draw a blood sample from a vein in your arm. Then, you will receive an injection (usually of ACTH or hCG). You will wait for 30 minutes, and then another blood sample will be drawn. The entire procedure usually takes about 45-60 minutes. You may experience mild discomfort during the blood draw, and the injection may cause a brief stinging sensation.

Reference range

Adult: 80-200 ng/dLN/A

Specimen: serum

No special preparation required; however, specimen should be collected at exactly 30 minutes post-challenge as part of dynamic endocrine testing protocol. Patient should remain at rest during the challenge period.

Frequently asked questions

Are there any risks or side effects?
The risks are minimal and include minor bruising, bleeding, or soreness at the injection site. Some people may feel dizzy or lightheaded during or after the blood draw. The stimulation injection (ACTH or hCG) is generally safe but may cause temporary flushing, headache, or mild nausea.
How long does it take to get results?
Results are typically available within a few days to a week, depending on the laboratory. Your healthcare provider will discuss the results with you during a follow-up appointment.
Do I need to do anything special after the test?
You can resume normal activities immediately after the test. If you feel dizzy or lightheaded, sit and rest for a few minutes before leaving. Follow any specific instructions given by your healthcare provider regarding medications or follow-up appointments.
Can this test be done at any time of day?
Yes, but ACTH stimulation tests are typically performed in the morning because ACTH levels naturally follow a daily rhythm, being highest in the morning. Your doctor will schedule the test at the appropriate time.
What medications might affect the test results?
Certain medications can interfere with the test, including corticosteroids, hormone replacement therapy, certain birth control pills, and medications that affect adrenal function. Always inform your doctor about all medications you are taking.
