What it measures

What the test involves
A healthcare professional collects a small sample of blood from a vein in your arm using a standard blood draw. The sample is then sent to a laboratory for analysis.
Why it is often ordered
A clinician may order this test to determine if ovulation is occurring, to investigate irregular menstrual cycles, or to monitor the effectiveness of fertility medications. It can also be used to check progesterone levels during early pregnancy or in women receiving hormone therapy.

Results are typically reported as a numerical value in nanograms per milliliter (ng/mL) or nanomoles per liter (nmol/L), along with a reference range. Reference ranges vary by laboratory and by the phase of your cycle, so your results should be interpreted by your healthcare provider.
