HCG Rapid Test Kit

INTENDED USE
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.

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/serum 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 (24 months).

ASSAY PROCEDURE
Remove the device from pouch by tearing and label the device with specimen identification.
Add 2-3 drops (70-100ul) of serum/plasma/urine to the s. Well. Observe the result in 5-10 minutes. DO not interpret results after 10 minutes.

INTERPRETATION OF RESULTS

Negative: Only one colored band appears on the control region (C). No colored band in the test region(T).
Positive: In addition to the control band (C), a distinct colored band also appears in the test region (T).
Invalid: If no bands appear, or a test band appears without a control band, the test should be repeated using a new test device.
