What is it used for?
A progesterone test is used to:
Find the cause of a woman's infertility (the inability to make a baby)
Find out if and when you are ovulating
Find out your risk of a miscarriage
Monitor a high-risk pregnancy
Diagnose an ectopic pregnancy, a pregnancy that grows in the wrong place (outside the uterus). A developing baby can't survive an ectopic pregnancy. This condition is dangerous, and sometimes life-threatening, for a woman.
