What Is A Progesterone Test?
Progesterone is a key hormone involved in the menstrual cycle, pregnancy and embryo development. This hormone is produced by the placenta in women during pregnancy and in small amounts by the adrenal glands in both men and women. The test is often recommended for women who face fertility issues, irregular menstrual cycles or pregnancy related concerns. In men, abnormal progesterone levels can indicate adrenal gland disorders or hormonal imbalances. Physicians also use this test to assess ovarian function, diagnose hormonal issues and monitor hormonal therapy.
By checking progesterone levels, healthcare professionals can check ovulation, evaluate health of pregnancy or diagnose conditions like polycystic ovary syndrome or adrenal gland disorders.
How is the Test Performed?
Sample Collection
A progesterone test requires a small blood sample, usually taken from a vein in the arm.
Lab Analysis
The blood is examined using immunoassay techniques to measure the level of progesterone concentration. Results help assess progesterone levels in relation to a woman’s menstrual cycle, pregnancy or overall health.
Result
Results are usually available within 24 hours.
What are the symptoms that prompt this test?
Women
- Irregular or absent menstrual periods

Men
- Low sex drive
- Fatigue and weakness
- Mood changes
- Adrenal gland disorders
Children
- Early or delayed puberty
- Hormonal imbalances leading to developmental issues
- Unexplained weight changes
What are Normal Ranges for This Test?
Progesterone levels vary with gender, age and menstrual cycle phase. In women progesterone levels are highest during pregnancy, while they decline overtime during menopause.
Women
- Follicular Phase –1–1.5 ng/mL
- Luteal Phase –2–25 ng/mL
- First Trimester of Pregnancy – 10–44 ng/mL
- Postmenopausal –Less than 1 ng/mL
Men
The normal levels in men is 0.1–0.3 ng/mL.
These ranges vary slightly depending on the testing methods used.
** Normal levels are dependent on a number of factors including age, gender, testing method and health condition of patient etc. Result interpretation should be done by a qualified doctor or healthcare professional.**
What Happens if Test Results Show Abnormal Levels?
Abnormal progesterone levels indicate underlying health issues.
High Progesterone – Indicates pregnancy, ovarian cysts or adrenal gland issues.
Low Progesterone –Indicates ovulation issues, miscarriage risk or hormonal imbalances.
In case of abnormal progesterone levels, your doctor may:
- Order additional hormone tests such as estrogen, testosterone or cortisol tests.
- Order imaging tests such as ultrasound, MRI to assess ovarian or adrenal functions.
- Suggest lifestyle modification or medications.
- Evaluate underlying issues such as PCOS, adrenal gland disorders or pregnancy complications.
