What is 17 Hydroxy Progesterone (17-OHP) test?

The 17-OHP test measures the level of 17-hydroxyprogesterone, a hormone produced by the adrenal glands and involved in cortisol production. It is mainly used to diagnose or monitor Congenital Adrenal Hyperplasia (CAH), a genetic disorder affecting adrenal hormone synthesis.

Who should take this test?

• Newborns screening for Congenital Adrenal Hyperplasia (CAH).
• Children with signs of early puberty.
• Women with irregular periods or excess facial/body hair.
• Individuals with suspected adrenal hormone imbalance.
• Doctor-advised evaluation of cortisol production disorders.

Preparation & Test Process

How to interpret results

Results are reported in ng/mL (or lab-specific units). Reference ranges vary based on age, gender, and testing method.

High levels may indicate Congenital Adrenal Hyperplasia (CAH) or adrenal overactivity.
Mild elevation may require further testing (ACTH stimulation test).
Low levels are usually not clinically significant but must be interpreted by a doctor.

This test is not a standalone diagnosis. Always consult your doctor for proper evaluation.
