Ordering the Progesterone Test
Progesterone testing helps track hormone changes that can affect menstrual cycles, fertility, and pregnancy. This test is often used to check if ovulation has occurred, monitor pregnancy health, or investigate symptoms like irregular periods. Interestingly, progesterone levels can also help doctors understand if certain medications are affecting hormone balance.
Ordering this test can provide:
- Clear information about ovulation timing for those trying to conceive
- Insight into possible causes of irregular menstrual cycles
- Support for monitoring early pregnancy health
- Guidance for evaluating hormone therapy effectiveness
- Data to help explain unexplained uterine bleeding
Who Might Benefit from Hormone Level Testing
People who are tracking their fertility, experiencing changes in their menstrual cycle, or monitoring pregnancy may find this test helpful. For example, someone who has been trying to get pregnant for several months without success may use this test to see if ovulation is happening as expected.
Ordering this test may also be useful in these situations:
- Someone with irregular or missed periods
- People with symptoms like spotting between cycles
- Those undergoing fertility treatments
- Pregnant people with a history of miscarriage
- Someone with adrenal gland concerns, since progesterone is also made in the adrenal glands
This test gives specific, measurable results that can help explain symptoms like missed periods or trouble getting pregnant. Delaying this test could mean missing the best window for treatment or support, especially when timing is important for fertility or pregnancy monitoring.
Preparing for Your Blood Hormone Assessment
Fasting is not needed before this test, so you can eat and drink as usual. Always follow any instructions your doctor or healthcare provider gives you, as they may have specific timing or scheduling advice for your situation.

Progesterone is a hormone made by the ovaries and adrenal glands. It helps regulate the menstrual cycle and supports pregnancy by preparing the uterus for a fertilized egg. |
High levels mean ovulation has likely occurred, or may indicate pregnancy or certain hormone-producing conditions.
Low levels mean ovulation may not have happened, or could point to problems with the ovaries or early pregnancy loss. |
Reference ranges can change over time. For the most current values, visit the Quest Diagnostics lab test directory.
