LH & FSH Test in Hisar

What is the LH & FSH Test?

The LH (Luteinizing Hormone) and FSH (Follicle‑Stimulating Hormone) test measures two key hormones produced by the pituitary gland that regulate the menstrual cycle and ovarian function.

Key Parameters

Why is it done?

• Routine evaluation of menstrual irregularities or infertility
• Assessment of ovarian reserve before assisted reproduction
• Investigation of early menopause or delayed puberty
• Monitoring response to hormonal therapies

Early Detection

This test can help identify signs of ovarian dysfunction, premature ovarian failure, or pituitary disorders, but it does not diagnose a condition on its own. A clinician interprets results alongside symptoms, history, and other investigations.

What Abnormal Results May Indicate

• High LH: Polycystic ovary syndrome (PCOS), premature ovarian failure, or pituitary adenoma
• Low LH: Hypothalamic‑pituitary suppression, menopause, or certain medications
• High FSH: Reduced ovarian reserve, early menopause, or ovarian failure
• Low FSH: Hyperthyroidism, pituitary dysfunction, or certain medications

Many factors—hydration, recent medications, stress, or menstrual cycle phase—can influence hormone levels.

Who Might Need This Test?

• Women with irregular periods or unexplained infertility
• Women planning assisted reproduction or undergoing ovarian stimulation
• Women experiencing early menopause symptoms
• Patients on hormonal therapies requiring monitoring

In short: LH & FSH testing provides insight into ovarian health and helps guide fertility and endocrine management.

Preparation for LH & FSH Test

• Fasting: No fasting required.
• If combined with fasting tests: Follow the longest fasting period required by any test in the panel.
• Sample collection: A small vein (usually in the arm) is cleaned, a needle inserted, and about 5 mL of blood drawn. The process takes 5–10 minutes.
• What to expect: A brief pinch and a short needle insertion; mild discomfort is normal.
• Precautions: Avoid alcohol and strenuous exercise 24 hours before the test. Inform the lab if you are on hormonal medications (e.g., birth control, hormone replacement) as they may affect results.
• Aftercare: Apply gentle pressure to the puncture site; you can resume normal activities immediately.
• Note: Confirm any specific preparation with your doctor or the lab. This information is educational and not a substitute for professional medical advice.
