17-OH Progesterone, LC/MS, Five Specimens
Use
The 17-OH Progesterone, LC/MS test is used to assess the levels of 17-hydroxyprogesterone in the blood across multiple points in time. This test is typically employed to evaluate adrenal gland function and can help diagnose congenital adrenal hyperplasia (CAH), a genetic disorder affecting adrenal hormone production. The test involves collecting an initial blood sample, administering a treatment such as a medication or glucola, and obtaining additional samples at specified intervals to observe how the 17-OH Progesterone levels change.
Special Instructions
This panel requires multiple specimen collection tubes to be drawn at different time points. It involves an initial baseline tube followed by administration of a therapeutic agent, with subsequent blood samples collected at set intervals. Clinicians should only order this test if a treatment is intended to be administered after the first draw. Coordination with the clinician is necessary to confirm the reason for ordering this test series.
Limitations
The test is specific to the measurement of 17-OH Progesterone and does not provide information on other hormones. The performance characteristics of this test were developed by LabCorp and have not been FDA cleared or approved. Variability in results may occur due to biological factors and the patient's physiological state at the time of testing.
