Additional Information

Clinical Significance: For confirmation of pregnancy. Important in diagnosis of ectopic pregnancy and multiple gestation. Interference: This test may exhibit interference when sample is collected from a person who is consuming a supplement with a high dose of biotin (also termed as vitamin B7 or B8, vitamin H, or coenzyme R). It is recommended to ask all patients who may be indicated for this test about biotin supplementation. Patients should be cautioned to stop biotin consumption at least 72 hours prior to the collection of a sample.

Note: This assay is used for pregnancy testing only, cannot be used as a tumor marker.
