Progesterone test: what it is for

Progesterone is a hormone made mainly by the ovary after ovulation. It prepares the womb for a pregnancy. If you do not ovulate, progesterone stays low and your periods often become irregular.

When it is done

Doctors mostly order it when you are trying for a pregnancy and they want to know whether you ovulate. They also order it when periods are irregular. In pregnancy it is measured only in particular cases, and your gynaecologist decides.

It is often called the day 21 progesterone because, in a 28-day cycle, day 21 is a week before your period. If your cycle is longer or shorter, the day changes: what counts is the week before your expected period.

How the progesterone test is done

It is a blood test, done at a Bianalisi lab without a prescription. You can add other tests to the same draw.
