About 17 Oh Progesterone Lab Test

KayaWell Icon

17-OH progesterone is a blood test that measures the amount of 17-OH progesterone. This is a hormone produced by the adrenal glands and sex glands.

Many medicines can interfere with blood test results. Your healthcare provider will tell you if you need to stop taking any medicines before you have this test. Do not stop or change your medicines without talking to your doctor first.

A blood sample is needed. Most of the time, blood is drawn from a vein located on the inside of the elbow or the back of the hand.

In infants or young children, a sharp tool called a lancet may be used to puncture the skin.

  • The blood collects in a small glass tube called a pipette, or onto a slide or test strip.
  • A bandage is put over the spot to stop any bleeding.

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/L
