Luteinizing Hormone (LH) Test

The Luteinizing Hormone (LH) test in serum is an important tool in assessing endocrine function, particularly in relation to reproductive health. This test is used to measure LH levels in the blood, a hormone secreted by the pituitary gland that plays a key role in regulating the menstrual cycle in women and stimulating testosterone production in men. The test is performed by drawing a blood sample, and it is preferred to be done at specific times during the menstrual cycle to obtain accurate results. LH levels help determine the phases of the menstrual cycle, such as ovulation, as well as assess the function of the ovaries and testes. The test can also be used in diagnosing conditions such as infertility, endocrine disorders, and polycystic ovary syndrome (PCOS). Interpreting the results of this test requires a comprehensive evaluation by a doctor, as levels can be affected by various factors such as age and health condition.
