Test Details
Methodology
Liquid chromatography/tandem mass spectrometry (LC/MS-MS)
Result Turnaround Time
3 - 6 days
Turnaround time is defined as the usual number of days from the date of pickup of a specimen for testing to when the result is released to the ordering provider. In some cases, additional time should be allowed for additional confirmatory or additional reflex tests. Testing schedules may vary.
Use
This test may involve significant risk and should be performed only by qualified personnel who are familiar with the test and who have taken adequate precautions to protect the safety of the patient. Every effort has been made to ensure accuracy in these recommendations, but clinicians must use their judgment and refer to specific pharmaceutical resources to determine appropriate drug dosages for their patients.
Special Instructions
Draw blood for baseline 17-OH progesterone. Inject cosyntropin 250 μg IM or IV (if IV, dilute cosyntropin in 2 to 5 mL of sterile saline and inject over two minutes). Draw blood for stimulated 17-OH progesterone 60 minutes after. See the online Endocrine Appendix: ACTH Stimulation for expected values for various steroids at baseline and after ACTH stimulation.
