This is a hormone produced by the adrenal glands and sex glands.Adrenal glandsThe adrenal glands are two small triangle-shaped glands in the upper abdomen. One gland is located on top of each kidney.Read Article Now Book Mark Article How the Test is Performed A blood sample is needed.

It is often done on infants who are born with outer genitals that do not clearly look like those of a boy or a girl.Congenital adrenal hyperplasiaCongenital adrenal hyperplasia is the name given to a group of inherited disorders of the adrenal gland. Inherited means the traits are passed down ...Read Article Now Book Mark Article This test is also used to identify people who develop symptoms of CAH later in life, a condition called nonclassical adrenal hyperplasia. A provider may recommend this test for women or girls who have male traits such as:Excess hair growth in places where adult men grow hair Deep voice or an increase in muscle mass Absence of menses Infertility Normal Results Normal and abnormal values differ for babies born with low birth weight. In general, normal results are as follows:Babies more than 24 hours old - less than 400 to 600 nanograms per deciliter (ng/dL) or 12.12 to 18.18 nanomoles per liter (nmol/L) Children before puberty around 100 ng/dL or 3.03 nmol/L Adults - less than 200 ng/dL or 6.06 nmol/LNormal value ranges may vary slightly among different laboratories. Talk to your provider about the meaning of your specific test results.The examples above show the common measurements for results of these tests. Some laboratories use different measurements or may test different specimens. What Abnormal Results Mean A high level of 17-OH progesterone may be due to:Tumors of the adrenal gland Tumors of the adrenal glandAdrenocortical carcinoma (ACC) is a cancer of the adrenal glands.
