TheFOB Rapid Test Device (Feces) is a rapid visual immunoassay for the qualitative, presumptive detection of human hemoglobin in human fecal specimens. This kit is intended for use as an aid in the diagnosis of lower gastrointestinal (g.i.) pathologies.
Principle of FOB Rapid Test Device
The FOB Rapid Test Device (Feces) detects human hemoglobin through visual interpretation of color development on the internal strip. Anti-human hemoglobin antibodies are immobilized on the test region of the membrane. During testing, the specimen reacts with anti-human hemoglobin antibodies conjugated to colored particles and precoated onto the sample pad of the test. The mixture then migrates through the membrane by capillary action and interacts with reagents on the membrane. If there is sufficient human hemoglobin in the specimen, a colored band will form at the test region of the membrane. The presence of this colored band indicates a positive result, while its absence indicates a negative result. The appearance of a colored band at the control region serves as a procedural control, indicating that the proper volume of specimen has been added and membrane wicking has occurred.
