The HCG s/u Gold Rapid Screen Test(RST)is a chromatographic immunoassay for the early detection of human chronic gonadotropin (HCG) in serum/plasma or urine specimens.
INTRODUCTION
HCG is a glycoprotein hormone secreted by the developing placenta during pregnancy. The concentration of HCG in serum is approximately equal to the concentration in urine. The concentrations of HCG in urine and serum continue to rise during the first trimester of pregnancy to as high as 100,000 mIU/ml. HCG appears in urine shortly after conception, and continues to increase during the early stages of pregnancy, making it an excellent indicator for the detection of pregnancy.
PRINCIPLE
The membrane of the test device was coated with anti HCG antibodies on the test region and goat anti mouse IgG antibodies on the control region. During the test, urine specimen is allowed to react with the HCG monoclonal antibody-colloid gold conjugate, which was pre-dried on the test strip. The mixture then moves upward on the membrane chromatographically by capillary action. For a positive specimen, the conjugate binds to the HCG forming an antibody-antigen complex. This complex is captured by anti HCG antibody immobilized on the test region (T) and produces a pink color band when HCG concentration is equal to or greater than 25mIU/ml. Absence of this colored band in the test region suggests a negative result. To serve as a procedural control, a colored band at the control region(C) will always appear regardless the presence or absence of HCG.
STORAGE
The kits should be stored at temperature 4-30°C� the sealed pouch for the duration of the shelf life (24months).
Our product is based on the theory of enzyme interaction. It is used to detect the HCG atom in urine speciment. The colour change could identify the test result directly. Assisting with the result,doctor could judge whether the patient is pregnant or not.

Explanation of the test
One step hcg pregnancy test strip (urine) is a rapid chromatographic immunoassay for the qualitative detection of human chorionic gonadotropin (hcg) in urine to aid in the early detection of pregnancy.
Human chorionic gonadotropin (hcg) is a glycoprotein hormone produced by the developing placenta shortly after fertilization. In normal pregnancy, hcg can be detected in both urine and serum as early as 7 to 10 days after conception (1-4). Hcg levels continue to rise very rapidly, frequently exceeding 100 miu/ml by the first missed menstrual period (2-4), and peaking in the 100, 000-200, 000 miu/ml range about 10-12 weeks into pregnancy. The appearance of hcg in both urine and serum soon after conception, and its subsequent rapid rise in concentration during early gestational growth, making it an excellent marker for the early detection of pregnancy.
One step hcg pregnancy test strip (urine) is a rapid test that qualitatively detects the presence of hcg in urine specimens at the sensitivity of 20 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, one step hcg pregnancy test strip (urine) shows no cross-reactivity interference from the structurally related glycoprotein hormones hfsh, hlh and htsh at high physiological levels.
