Why have this check up?

The 17-hydroxyprogesterone (17-OHP) test is routinely ordered as part of newborn screening to detect congenital adrenal hyperplasia (CAH) due to 21-hydroxylase deficiency. This test may sometimes be ordered in older children or in adults when the milder form of CAH (late-onset) is suspected. The 17-OHP test may also be conducted when a girl or woman is experiencing symptoms that may be due to CAH or may be due to another condition, such as PCOS. Symptoms may include: >Excess facial and body hair (hirsutism) >Lack of or irregular menstrual periods (menses) >Development of male secondary sex characteristics >Infertility Testing may be performed on boys or men when they experience: >Early (precocious) puberty >Infertility
