Progesterone

What Affects the Test

Reasons you may not be able to have the test or why the results may not be helpful include:

• The use of hormones, including those containing estrogen or progesterone (such as birth control pills).
• The use of medicines, such as ampicillin and clomiphene.
• The time of day when you have the test. Progesterone levels normally fluctuate during the day.
• Exercise.
• Having a test such as a thyroid scan or bone scan that used a radioactive substance (tracer) within 1 week before the progesterone test.
• Where you are in your menstrual cycle.
