Triple Stimulation Test for Ovarian Function (Serum LH, FSH, Estradiol)

This test measures the levels of specific hormones in your body. It helps your doctor see how well glands such as the pituitary, thyroid, or adrenal glands are working, and whether they are producing too much or too little of these chemical messengers that regulate growth, metabolism, stress response, and reproduction.

Your blood will be drawn at three different times: baseline, after a hormone trigger (like GnRH), and after a second stimulation. The test checks for changes in LH (luteinizing hormone), FSH (follicle-stimulating hormone), and estradiol (a form of estrogen) to see how your ovaries react to these signals.

Your doctor may order this test to help find the cause of symptoms like fatigue, weight changes, weakness, or irregular menstrual cycles, to confirm a suspected hormonal imbalance, to monitor a condition you already have, or to check whether your current treatment is working as expected over time.

Doctors may order this test if you’re exploring fertility options, investigating unexplained infertility, or preparing for assisted reproductive technologies. It helps determine if your ovaries are functioning normally and how they might respond to fertility treatments.

The test typically involves giving you a medication, either by injection or by mouth, that stimulates or suppresses your hormone-producing glands. Blood samples are then drawn at set intervals so the laboratory can measure how your hormone levels change in response and compare those results with normal, expected patterns.

You’ll receive small injections or pills to stimulate your ovaries, and your blood will be tested at scheduled intervals. The results compare hormone levels before and after stimulation to check for typical responses.

Before the test, your care team will review your medications, because some drugs can affect the results, and they will tell you whether you need to fast or temporarily stop certain medicines. Plan to arrive on time, wear clothing that allows easy access to your arm for blood draws, and ask questions beforehand.

No special preparation is needed, but you may need to avoid certain medications or activities depending on your doctor’s instructions. Follow-up appointments will be scheduled to collect blood samples at each stage.
