General property of stool Microscopy Occult blood test Bacteriological examination

General property of stool watery stool: infectious and non-infectious diarrheas mucus stool: inflammatory diarrheas Pyohematochezia stool脓血便: bacterial dysentery, ulcerative colitis, Crohn’s disease,rectum carcinoma, colon carcinoma hematochezia stool: bloody diarrhea, hemorrhoid ischemic colitis, amebie dysentery, rectocolitis melena or tarry stool: a sign of bleeding from an upper digestive tract: gastric ulcer, carcinoma of stomach kaolin stool: biliary obstruction

Pyohematochezia stool

melena or tarry stool

Microscopy Cells: WBC:normal 0~1/HP, >15/HP inflammation RBC:normal:0, RBC (+~+++) : dysentery, carcinoma of GI, ulcerative colitis macrophage:normal: 0, (+): colitis , bacterial dysentery tumor cell: colon carcinoma, rectum carcinoma Ovum of parasite（寄生虫卵） : roundworm, hookworm , tenia

Occult blood test GI bleeding is a common clinical problem. Blood loss ranges from occult bleeding of which the patient is unaware to massive bleeding that anyone would notice( melena or bloody stool). Positive occult blood test is usually due to chronic GI blood loss, both upper and lower GI lesion such as peptic ulcer, stomach carcinoma, and colon carcinoma. It is a screening test for digestive carcinoma especially for elderly people .
