17-OH progesterone
Alternate Names : 17-hydroxyprogesterone, Progesterone - 17-OH
Normal Values
Normal and abnormal values differ for babies born with low birth weight. In general, normal results are as follows: - Cord blood - 1,000 - 3,000 ng/dL
- >24 hours - less than 100 ng/dL
- Adults - less than 200 ng/dL
Note: ng/dL = nanograms per deciliter. Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
What do Abnormal Results Mean?
High levels of 17-OH progesterone may be due to: - Adrenal tumors
- Congenital adrenal hyperplasia (CAH)
In infants with CAH, 17-OHP levels range from 3,000 - 40,000 ng/dL. In adults, a level greater than 200ng/dL may be due to nonclassical adrenal hyperplasia.
