Luteinizing Hormone (LH), Four Specimens
Use
Luteinizing hormone (LH) testing is important for assessing the function of the reproductive system. It plays a vital role in both male and female fertility, influencing the menstrual cycle, ovulation, and sperm production. Monitoring LH levels is critical for diagnosing fertility-related issues, investigating menstrual irregularities, and understanding certain conditions such as polycystic ovary syndrome and hypogonadism.
Special Instructions
The test requires sequential sampling. It is important to check for biotin interference, as high doses of biotin can affect the results. Patients should discontinue biotin supplements at least 72 hours before sample collection.
Limitations
The test may be affected by biotin interference, which can lead to inaccurate results. Therefore, patients taking biotin (vitamin B7 or B8) supplements must halt them at least 72 hours prior to the test. Additionally, variations in LH levels can occur due to several factors, including time of day and menstrual cycle phase, which can affect test interpretation.
