The progesterone blood test measures levels of this essential reproductive hormone during the part of your cycle after ovulation should have occurred (eg, day 21 of a 28-day cycle). A higher level may mean ovulation was successful. A lower level may point to potential fertility issues.
No doctor’s visit needed.
Our Progesterone Test measures the level of progesterone in your blood 21 days into your menstrual cycle. This level is based on a 28-day cycle or 7 days before the start of your next menstrual period.
This test can indicate if ovulation occurred, but does not predict the most fertile days of your cycle.
This test should be taken 7 days before the start of your next menstrual period (example: 21 days into a 28-day cycle)
