Progesterone Blood Test
A progesterone test evaluates the quantity of progesterone in the blood, primarily produced in the ovaries. During pregnancy, progesterone plays a crucial role. Progesterone helps prepare the uterus for a fertilised egg that is ready for implantation. It is produced during the second phase of menstruation following ovulation. Preventing the uterine muscle from contracting also helps prepare the uterus for pregnancy and the breasts for milk production.
What does a progesterone test entail?
Throughout a woman’s menstrual cycle, her progesterone levels will fluctuate. Progesterone levels will initially be low and then increase after the ovary releases an egg. Progesterone levels will gradually increase during pregnancy to prepare your body to support the growing foetus. Progesterone levels will drop if there is no pregnancy, meaning the egg has not been fertilised, and a menstrual period will start.
Progesterone levels in pregnant women are approximately ten times higher than those in non-pregnant women. Although they produce it in somewhat smaller amounts, men also produce progesterone. Women’s ovaries produce progesterone, while men’s testes and adrenal glands do the same. This test is also known as the progesterone blood test, serum progesterone, or a PGSN.
What do I need to do to prepare for a progesterone test?
A sample of your blood will be drawn and sent to the lab for the test, and you might be requested to complete some tasks prior to the test. The results of your test could be affected by any medications you are currently taking, such as progesterone supplements and birth control pills. Kindly inform your health provider about this, as it can affect the accuracy of your test.
Why would a progesterone test be necessary for me?
Your doctor may prescribe a progesterone test to:
- Determine whether you are experiencing any reproductive problems.
- Determine the time of ovulation.
- Determine whether you run the risk of miscarriage.
- To monitor high-risk pregnancies
- To diagnose ectopic pregnancies in which the egg has started to develop outside the womb. Being outside the uterus prevents an egg from developing, which is a life-threatening condition.
During your progesterone test
A tiny needle will be used to draw blood from your arm’s vein. The blood sample collection takes only a few minutes, though you might experience a minor stinging sensation when the needle is inserted or removed. No special preparation is needed for this test.
What are the risks associated with a progesterone test?
There is relatively minimal danger involved with a progesterone blood test. The area where the needle was inserted may cause slight discomfort or bruising, but these side effects won’t last long.
