What is the 17 Hydroxyprogesterone ( OHP) test?

17 Hydroxyprogesterone is a hormone made by the adrenal glands, which are present above the kidney. 17 hydroxyprogesterone acts as a building block for producing cortisol hormone. The cortisol hormone maintains blood pressure, the immune system, and blood sugar. In certain conditions, the 17 hydroxyprogesterone (OHP) may be produced at a low or higher level. This leads to impaired formation of the cortisol hormone, which affects certain body functions. 17 hydroxyprogesterone test measures the level of 17 hydroxyprogesterone(OHP) in the blood.
