About 17 hydroxyprogesterone

What is 17-hydroxyprogesterone?

17-Hydroxyprogesterone (also known as hydroxyprogesterone) is a steroid hormone produced by the adrenal glands. It is an important precursor for glucocorticoids and sex hormones.

Hormones are chemical messengers used by the body to respond to internal and external influences. The activity of hormones must be finely regulated to produce the desired physiological effect. This regulation is typically coordinated by complex interactions between several different hormones. Both excessive production and a deficiency in the production of steroid hormones can cause ill health. 

Disorders related to 17-Hydroxyprogesterone include congenital adrenal hyperplasia, a rare disorder characterised by low levels of cortisol and high levels of male hormones. 

Why take the test?

This test measures the level of 17-hydroxyprogesterone and can be used to help diagnose steroid synthesis disorders, including congenital adrenal hyperplasia.
