Human chorionic gonadotropin is a glycoprotein hormone produced by the developing placenta shortly after fertilization. In normal pregnancy, hCG can be detected in urine as early as 7 to 10 days after conception.1,2,3,4 hCG levels continue to rise very rapidly, frequently exceeding 100 mIU/mL by the first missed menstrual period,2,3,4 and peaking in the 100,000-200,000 mIU/mL range about 10-12 weeks into pregnancy.
The appearance of hCG in urine and its subsequent rapid rise in concentration during early gestational growth make it an excellent marker for the early detection of pregnancy. The hCG Pregnancy Test is a rapid test that qualitatively detects the presences of hCG in urine specimen at the sensitivity of 25 mIU/mL. The test utilizes a combination of monoclonal and polyclonal antibodies to selectively detect elevated levels of hCG in urine. At the level of claimed sensitivity, the hCG Pregnancy Test shows no cross-reactivity interference from the structurally related glycoprotein hormones hFSH, hLH and hTSH at high physiological levels.
The hCG pregnancy test will detect the presence of hCG in urine as early as the first day of a missed period. The concentration of hCG continues to rise rapidly, frequently exceeding 100 mIU/ml by the first missed menses and peaking in the 30,000 ~ 100,000 mIU/ml range by 10 to 12 weeks into pregnancy. The hCG pregnancy test is an in-vitro immunochromatographic one step assay designed for qualitative determination of hCG in urine. This test kit uses specific antibodies to selectively identify hCG in urine with a high degree of sensitivity. Elevated levels of hCG as low as 25 mIU/ml and be detected within 3 minutes. It is intended for professional use. The hCG pregnancy test contains a membrane strip, which is pre-coated with goat anti-hCG capture antibody on test band region.
The mouse anti-beta hCG monoclonal antibody-colloid gold conjugate and urine sample moves along the membrane chromatographically to the test region (T) and forms a visible line as the antibody-antigen-antibody gold particle complex forms. The hCG pregnancy test device has a letter of T and C as "Test Line" and "Control Line" on the surface of the case. Both the Test Line and Control Line in result window are not visible before applying any samples. The Control Line is used for procedural control. Control line should always appear if the test procedure is performed properly and the test reagents of control line are working.
One-Step HCG Urine Rapid Test is a test kit for the determination of hCG (Human Chorionic Gonadotropin) in urine specimens. There is an appearance of hCG in urine soon after conception, and its subsequent rapid rise in concentration during early gestational growth. This test is used to obtain a visual, qualitative result for the early detection of pregnancy.
