Progesterone, Immunoassay
Use
The Progesterone Immunoassay measures serum progesterone levels to evaluate progesterone status, typically in reproductive and fertility contexts, such as confirming ovulation or evaluating luteal function.
Special Instructions
DHEA supplementation may falsely elevate progesterone results in this immunoassay method; in such cases or when IVF-trigger thresholds are essential, an LC/MS/MS assay (order code 17183) is recommended. Do not add on progesterone testing to a barrier-gel specimen older than 72 hours.
Limitations
DHEA supplementation causes false elevation of values in this standard immunoassay. Barrier gel specimens older than 72 hours may yield invalid results if used for add-on testing.
