Also known as: Progesterone Immunoassay


Serum progesterone is a test to measure the amount of progesterone in the blood. Progesterone is a hormone produced mainly in the ovaries. In women, progesterone plays a vital role in pregnancy. After an egg is released by the ovaries (ovulation), progesterone helps make the uterus ready for implantation of a fertilized egg. It prepares the womb (uterus) for pregnancy and the breasts for milk production. Men produce some amount of progesterone, but it probably has no normal function except to help produce other steroid hormones.

Progesterone Lab Test Overview

A Progesterone lab test is a diagnostic examination that measures the levels of the hormone progesterone in a person's blood. Progesterone is a crucial hormone primarily produced by the ovaries in women (and in smaller amounts by the adrenal glands) and plays a pivotal role in various reproductive and physiological functions. This test helps healthcare providers assess a patient's hormonal status and may be ordered for several reasons.

Important: For patients under 18 years old, Progesterone, Immunoassay reference ranges have not been established for pre-pubertal patients. For pre-pubertal patients, Progesterone, LC/MS/MS #171183 is recommended.

Also Known As: PGSN Test

Collection Method: Blood Draw

Specimen Type: Serum

Test Preparation: No preparation required

Note: DHEA supplementation causes a false elevation of values in this standard Immunoassay method for Progesterone. Physicians using Progesterone levels as a criterion for triggering ovulation in an IVF cycle in patients supplemented with DHEA should assess Progesterone levels using a Progesterone LC/MS/MS #17183.

When and Why a Progesterone Lab Test May Be Ordered

Timing of the Test: The Progesterone lab test is often ordered during a specific phase of a woman's menstrual cycle, usually between days 21 and 23 (counting from the first day of menstruation), when progesterone levels typically peak. However, it can also be done at other times as needed.

Reasons for Ordering the Test:

  1. Assessment of Ovulation: One common reason for this test is to confirm whether a woman is ovulating. A surge in progesterone occurs after ovulation, and measuring its levels can indicate whether an egg has been released from the ovary.

  2. Evaluation of Fertility: For couples experiencing difficulty conceiving, a Progesterone test can help determine if there are hormonal issues affecting fertility, such as insufficient progesterone production.

  3. Monitoring Pregnancy: Progesterone is vital for maintaining a healthy pregnancy. This test may be used to monitor progesterone levels during pregnancy, especially if there is a history of miscarriage or other complications.

  4. Assessment of Menstrual Irregularities: In cases of irregular or absent menstrual periods, the test can help diagnose hormonal imbalances or conditions like polycystic ovary syndrome (PCOS).

  5. Evaluation of Menopause: Progesterone levels decrease as a woman approaches menopause, and this test can assist in confirming menopausal status.

What a Progesterone Lab Test Checks For

The Progesterone lab test measures the concentration of progesterone in the bloodstream. Progesterone is essential for:

  • Preparing the uterine lining for pregnancy.
  • Supporting early pregnancy by maintaining the uterine environment.
  • Regulating the menstrual cycle.
  • Aiding in breast development during pregnancy.

How Health Care Providers Use the Results

Interpreting the results of a Progesterone lab test depends on the clinical context:

  1. Ovulation Confirmation: If progesterone levels are elevated during the luteal phase of the menstrual cycle, it confirms that ovulation has occurred, which can be important for fertility assessments.

  2. Pregnancy Monitoring: In pregnant individuals, the test helps assess the viability of the pregnancy. Low progesterone levels may indicate a higher risk of miscarriage or other complications.

  3. Hormone Imbalance Diagnosis: Abnormal progesterone levels can indicate hormonal imbalances or conditions like PCOS, helping healthcare providers make accurate diagnoses.

  4. Menopause Confirmation: Low progesterone levels, along with other hormonal changes, can confirm menopausal status in women.

Overall, the Progesterone lab test is a valuable tool for healthcare providers in assessing reproductive health, diagnosing hormonal disorders, and monitoring pregnancies, contributing to informed decision-making and appropriate treatment recommendations.

We advise having your results reviewed by a licensed medical healthcare professional for proper interpretation of your results.
