Disease Type:

Human transferrin Antigen Rapid Test Kit (Colloidal gold) is a qualitative, transversal test kit for flow immunoassay detection of human occult blood in stool. The membrane is pre-coated with anti-transferrin antibodies on the test line area of the strip. During the interim test, the sample reacts with particles coated with anti-transferrin antibodies. This mixture migrates up the membrane through capillary action and reacts with anti-transferrin antibodies on the membrane to form a colored line.
The presence of this colored line in the test area indicates a positive result, while its absence indicates a negative result. As a program control line will always appear in the control line area, indicating that the sample has been added and the film wick has occurred.

The main components of the test box:
Mouse anti-human transferrin antibody, goat anti-Rabbit IgG polyclonal antibody, human transferrin antibody, Rabbit IgG, colloidal gold conjugate, other test equipment, support a desiccant.
Main components of the sample diluent:
Neutral salt buffer and reagents of different batches cannot be used interchangeably.


Transferrin is a specific protein abundant in human plasma.
