Human Chorionic Gonadotropin (hCG), β-Subunit, Qualitative
Also known as: hCG, β-Subunit, Qualitative, Pregnancy Test
Use
Immunoassay for the in vitro quantitative determination of the sum of human chorionic gonadotropin (hCG) plus the hCG beta-subunit in human serum and plasma.1This assay is intended for the early detection of pregnancy.
Special Instructions
Patients who are consuming supplements with high doses of biotin should be advised to stop biotin intake at least 72 hours prior to specimen collection, as this can cause test interference.
Limitations
The test may produce erroneous results in samples collected from patients treated with monoclonal mouse antibodies or those who have received monoclonal antibodies for diagnostic purposes. Additionally, rare interference from high levels of antibodies to streptavidin and ruthenium could occur, although additives in the test are designed to minimize these effects.
