Luteinizing Hormone (LH), Five Specimens
Use
Luteinizing hormone (LH) is an important component of the menstrual cycle and helps regulate ovulation in females. It also plays a role in testosterone production in males. Measuring LH levels can aid in diagnosing reproductive and hormonal disorders, such as infertility, menstrual irregularities, and pituitary gland tumors. This test involves sequential sampling across five different time points to monitor the LH levels more accurately across a cycle.
Special Instructions
Please refer to the directions for Sequential Sampling. Patients consuming high doses of biotin supplements should be cautioned to stop consumption at least 72 hours prior to sample collection. High biotin levels may interfere with test results.
Limitations
Interference in test results may occur if the sample is collected from a person taking high doses of biotin supplements. Accurate timing of sample collection is crucial for reliable results, particularly in sequential sampling. This test is not intended for use as a screening test for early pregnancy.
