Intended Use: A doctor may order progesterone testing for women undergoing evaluation for infertility. It is also used to monitor ovulation, diagnose an ectopic pregnancy or monitor a high-risk pregnancy.
Limitations: In rare cases, interference due to extremely high titers of antibodies to analyte-specific antibodies, streptavidin or ruthenium can occur. Phenylbutazone at therapeutic dosage levels causes depressed progesterone values.
