Intended use

Fecal Occult Blood (FOB) Test (Colloidal Gold) is used for qualitative detection of hemoglobin in human feces at home for self-testing, or at all levels of medical institutions for testing, so as to provide auxiliary diagnosis for digestive tract haemorrhagic disease.

Test principle

This assay is a one-step lateral flow chromatographic immunoassay. The test strip consists of: 1) a burgundy colored conjugate pad containing mouse anti-hHb antibodies conjugated with collagenal gold and 2) antrocellular membrane strip containing a Test line (T- and a Control line (C-line). The T-line is coated with anti-hHb antibodies, and the C-line is coated with goat anti-mouse IgG antibodies. When an adequate volume of test specimen is dispensed into the sample well of the device, the test specimen migrates by capillary action across the test strip. If the concentration of hHb in the specimen is at or above 50 ng/ ml, the T-line appears as a visible burgundy line. If the concentration of hHb in the The specimen is below the detectable level, no T-line develops.
