Luteinizing Hormone (LH), Seven Specimens
Use
The Luteinizing Hormone (LH) test is used for evaluating the function of the gonads (ovaries or testes), diagnosis of conditions related to pituitary gland disorders, fertility problems, and assessment of disorders of sexual development. LH is a key hormone in regulating the menstrual cycle and ovulation in women, and it functions in the production of testosterone in men. Monitoring LH levels can help in determining the cause of issues like infertility, early or delayed puberty, and can aid in the evaluation of menstrual irregularities.
Special Instructions
Patients should be advised to discontinue biotin supplements at least 72 hours prior to specimen collection, due to potential interference with the test results. Sequencing sampling instructions should be followed carefully for accurate results.
Limitations
This LH test may be affected by high doses of biotin consumption. Results could be altered if samples are collected from patients taking supplements containing high doses of biotin, commonly found in hair, skin, and nail products. Additionally, LH test results may be influenced by medications affecting hormonal balance. For accurate interpretation, clinical correlation with patient history and other hormone assays is necessary.
