Problems solved by technology
[0002] At present, most of the clinical in vitro diagnostic equipment for the detection of fecal occult blood in fecal samples is colloidal gold immunoassay, which can only be used for clinical fecal occult blood qualitative, but cannot judge the amount of gastrointestinal bleeding, and the interpretation of the results is subjective. Experience is closely related
Qualitative test results can only reflect whether there is bleeding, and the amount of bleeding can only be obtained through quantitative or semi-quantitative analysis of fecal occult blood, which may even increase manual workload and greatly reduce the efficiency and accuracy of detection

The invention provides a fecal occult blood detection semi-quantitative method which comprises the following steps: dropwise adding a diluted sample into a sample application hole in a colloidal gold detection card through a sample application device, taking a picture after qualitative negative and positive are preliminarily shown, and reading a qualitative result on a display by a reading instrument; after a qualitative result is read, firstly dropwise adding a certain amount of 3, 3, 5, 5-tetramethyl benzidine indicating solution into the same sample application holes, and then dropwise adding a certain amount of hydrogen peroxide solution; after the 3, 3, 5, 5-tetramethyl benzidine indication solution and the hydrogen peroxide solution are dropwise added for a period of reaction time, the colloidal gold detection card shows a semi-quantitative result, and photographing is carried out again to read the semi-quantitative result. According to the invention, the semi-quantitative result of fecal occult blood detection is increased, the manual operation is reduced, and the manual workload is reduced, so that the defects of fecal occult blood detection in clinical examination are overcome, the work of manual reexamination is greatly reduced, and the accuracy of the detection result is ensured.
Description
technical field [0001] The technical field of clinical stool detection of the present invention, in particular relates to a semi-quantitative method for detection of fecal occult blood. Background technique [0002] At present, most of the clinical in vitro diagnostic equipment for the detection of fecal occult blood in fecal samples is colloidal gold immunoassay, which can only be used for clinical fecal occult blood qualitative, but cannot judge the amount of gastrointestinal bleeding, and the interpretation of the results is subjective. Experience is closely related. Qualitative test results can only reflect whether there is bleeding, and the amount of bleeding can only be obtained through quantitative or semi-quantitative analysis of fecal occult blood, which may even increase the workload of humans and greatly reduce the efficiency and accuracy of detection. [0003] Therefore, the present invention provides a semi-quantitative method for detecting fecal occult blood, ...
