Description
The ClearSign Midstream Pregnancy Test is a HCG midstream test that is over 99% accurate and can display a positive result in as soon as 1 minute. The test is easy to read, and can be used for self-testing, or can also be used by medical professionals.
The ClearSign Midstream Pregnancy Test is a rapid one-step test based on immunochromatographic technology. A membrane with an absorbent pad over a strip of fiber glass is impregnated with a colloidal conjugate of gold particles and monoclonal antibodies to HCG. Other absorbent pads at the end of the assay absorb excess sample fluid. The urine sample is introduced into a chromatographic membrane, and as it contacts the membrane, the sample dissolves the lyophilized conjugate. In a reactive sample, the HCG antigen will attach to the antibodies in the colloidal solution. As the conjugate moves forward on the membrane, anti-HCG monoclonal antibodies affixed on the test zone (“T”) will bind the HCG-gold conjugate complex, forming a pink line (“T”). Any sample will cause a pink coloured line to appear in the control zone (“C”) – this line is formed by the binding of polyclonal antibodies (Anti-mouse lgG) affixed onto the control zone to the sample-colloidal gold conjugate. Presence of this line indicates that the test has been carried out correctly.
