    Luteinizing Hormone

    How It Feels

    Blood test

    You may feel nothing at all from the needle puncture, or you may feel a brief sting or pinch as the needle goes through the skin. Some people feel a stinging pain while the needle is in the vein. But many people do not feel any pain (or have only minor discomfort) once the needle is positioned in the vein.

    Urine test

    Collecting a urine sample does not normally cause any discomfort.

    Risks

    Blood test

    • You may develop a small bruise at the puncture site. You can reduce the risk of bruising by keeping pressure on the site for several minutes after the needle is withdrawn.
    • In rare cases, the vein may become inflamed after the blood sample is taken. This condition is called phlebitis and is usually treated with a warm compress applied several times daily.
    • Continued bleeding can be a problem for people who have bleeding disorders. Aspirin, warfarin (Coumadin), and other blood-thinning medicines can also make bleeding more likely. If you have bleeding or clotting problems, or if you take blood-thinning medicine, tell your doctor before your blood is drawn.

    Urine test

    There are no risks linked with collecting a urine sample.

    Results

    A luteinizing hormone test measures the amount of luteinizing hormone (LH) in a sample of blood or urine.

    LH levels depend on a person's age and stage of sexual development, and, in a woman, on the phase of her menstrual cycle. The urine test to determine whether a woman is ovulating detects only the presence (positive result) or absence (negative result) of LH.

    Normal

    The normal values listed here-called a reference range-are just a guide. These ranges vary from lab to lab, and your lab may have a different range for what's normal. Your lab report should contain the range your lab uses. Also, your doctor will evaluate your results based on your health and other factors. This means that a value that falls outside the normal values listed here may still be normal for you or your lab. Ask your doctor for normal values of your luteinizing hormone test.
