Thanks for posting on HCM,Progesterone
test is done to:
- Determine if a woman is ovulating
- Evaluate a women with repeated miscarriages, but other diagnostic tests and treatment are more commonly used for this purpose
- Determine the risk of miscarriage or ectopic pregnancy
early in pregnancy
Progesterone levels vary depending on when the test is done. Blood progesterone levels start to rise midway through the menstrual cycle, continue to rise for about 6 to 10 days, and then fall if fertilization does not result.
Levels continue to rise in early pregnancy.
The following are normal ranges based upon certain phases of the menstrual cycle and pregnancy:
Pre-ovulation: less than 1 ng/mL (3.18nmol/l)
Mid-cycle: 5 to 20 ng/mL (15.9-63.6 nmol/l) around the 14th day of cycle
Postmenopausal: less than 1 ng/mL
Pregnancy 1st trimester: 11.2-90.0 ng/mL
Pregnancy 2nd trimester: 25.6-89.4 ng/mL
Pregnancy 3rd trimester: 48.4-42.5 ng/mL
Note: ng/mL = nanograms per milliliter
Note: Normal value ranges may vary slightly among different laboratories. Talk to your doctor about the meaning of your specific test results.
Those are the standard normals, but as I said, you need to see your doctor for specific test.
You might have gone through anuvolution which could have been responsible for low progesterone level. Repeat testing in subsequent months is advised.
Hope this helps
