LH
This test measures the level of luteinizing hormone (LH). A hormone is a chemical messenger in your bloodstream that controls the actions of certain cells or organs. LH is usually measured in a sample of your blood. But in certain cases, it may be measured in urine (pee).
LH testing is used to help diagnose conditions that cause too much or too little LH. The specific way the test is used depends on your sex, age, and symptoms.
