A weakly positive fecal occult blood test means that the stool contains red blood cells, but not in large amounts. Fecal occult blood means that there is a small amount of bleeding in the digestive tract, the red blood cells are destroyed, and the stool contains a small amount of blood that is not visible to the naked eye and has to be examined under a microscope. Weakly positive fecal occult blood suggests the presence of a small number of red blood cells in the stool. Possible causes include chronic gastric diseases such as peptic ulcer, erosive gastritis, intestinal diseases such as enteritis, intestinal tumors, etc., which require gastro-enteroscopy and other tests to make a clear diagnosis. In addition, consumption of animal blood products such as goat’s blood and pig’s blood can also cause weak positive fecal occult blood. Weakly positive fecal occult blood test usually does not have much diagnostic significance, and the results can be reviewed several times to make sure the results are reliable. If the patient has a weak positive fecal occult blood test, it is recommended to go to a regular hospital in a timely manner, to identify the cause of the disease, and then carry out targeted treatment under the guidance of the doctor, in order to reduce the adverse effects of the disease.
