17-OH Progesterone, LC/MS, Seven Specimens
Use
This test is used to measure the level of 17-hydroxyprogesterone (17-OH Progesterone) in the blood. It is typically used in the evaluation of patients with suspected congenital adrenal hyperplasia (CAH), a genetic disorder affecting adrenal gland function that can cause abnormal hormone levels and affect sexual development. Monitoring 17-OH Progesterone levels is crucial for diagnosing and managing CAH, particularly in assessing the need for specific treatments such as glucocorticoid replacement therapy.

Limitations
The test results must be evaluated with caution in the context of the patient's clinical presentation and other diagnostic tests. The presence of cross-reactivity with similar steroids may influence results. False results may occur if the samples are not collected according to the specified protocol, such as incorrect timing of sample collections. Possible technical variations in LC/MS methods might also impact outcomes, and confirmatory testing or alternative methods may be necessary for ambiguous results.
