I was just looking online because with what my doc told me and my levels were 17 ne month and 19 the next, so I did some research. This is what I found out:
Progesterone (P4) 7 dpo > 15 ng/ml A progesterone test is done to confirm ovulation. When a follicle releases its egg, it becomes what is called a corpus luteum and produces progesterone. A level over 5 probably indicates some form of ovulation, but most doctors want to see a level over 10 on a natural cycle, and a level over 15 on a medicated cycle. There is no mid-luteal level that predicts pregnancy. Some say the test may be more accurate if done first thing in the morning after fasting.
Hope this helps!!!
