Luteinizing Hormone (LH), Pediatric (Endocrine Sciences)
Also known as: LH, 3rd Generation
Use
The Luteinizing Hormone (LH) test is commonly used in pediatric settings to evaluate the function of the pituitary gland and menstrual cycle in children. It is significant in diagnosing conditions related to hormonal imbalance such as precocious puberty or delayed puberty in children. Understanding the levels of LH in the body can inform medical decisions regarding growth and development issues, and guide treatment in cases of endocrine disorders.
Special Instructions
Serum or plasma must be separated from cells within 45 minutes of venipuncture. It is important to send serum or plasma in a plastic transport tube to avoid delays in turnaround time, especially when requesting multiple tests on frozen samples; separate frozen specimens should be submitted for each test requested.
Limitations
The test was developed and its performance characteristics determined by LabCorp. It has not been cleared or approved by the Food and Drug Administration. Results should be interpreted in the context of the patient's clinical condition and other diagnostic tests. Certain factors such as hemolysis, lipemia, or improper sample handling may affect the result accuracy.
