What is it?

A Luteinizing Hormone (LH) test measures the amount of LH in your blood. LH is a hormone produced by the pituitary gland. In women, LH plays a key role in ovulation and the menstrual cycle. In men, it helps regulate testosterone production.

Who is it for?

This test is often recommended for:

• Women: To evaluate fertility, diagnose menstrual irregularities, or monitor hormone therapy.
• Men: To assess male infertility or hormonal imbalances.
• Children: To evaluate puberty development.

Outcome of the test:

The results of an LH test can help determine:

• Women: If ovulation is occurring, if there are hormonal imbalances, or if hormone therapy is effective.
• Men: If there are issues with testosterone production or sperm quality.
• Children: If puberty is progressing normally.

Preparation before taking the test:

• Fasting: You may be asked to fast for a certain period before the test.
• Medications: Inform your healthcare provider about any medications you are taking, as some can affect LH levels.
• Stress: Try to avoid significant stress before the test, as it can temporarily affect hormone levels.

Note: The specific preparation guidelines may vary depending on your healthcare provider and the reason for the test. It’s essential to follow their instructions carefully.
