The Lab21 range of pregnancy tests.

Screening for pregnancy by latex agglutination methodology has remained extremely popular over the years, despite the introduction of an increasing number of test choices. Human chorionic gonadotrophin (hCG) present in a urine sample from a pregnant woman reacts with monoclonal anti-hCG antibodies bound to latex beads. Cross-bridging of adjacent beads occurs producing a strong visible agglutination. Sensitivity of the assay is 200 IU/L.

The rapid test is a chromatographic immunoassay for the qualitative detection of hCG in urine and/or serum, to aid in the early detection of pregnancy. The test utilises a combination of antibodies including monoclonal hCG antibody to selectively detect elevated levels of hCG in urine, at the sensitivity of 25 mIU/mL.

The EIA test is a quantitative assay for the determination of ß-hCG (human chorionic gonadotropin ß-chain) in human serum or plasma. It provides early detection of pregnancy, chorion epithelioma and embryonic cell carcinoma.
