Diagnosis with<unk>  is difficult to do until symptoms appear. The amoeba will form cysts and trophozoites in the gastrointestinal tract. This can cause abdominal pain and diarrhea. Once symptoms start to occur, the standard means of diagnosing are a series of stool sample examinations and serological testing, and, if necessary, a colonoscopy or a biopsy of intestinal amebic legions or draining of liver abscesses (if present). They are checking to see if there is any indication of the amoeba within the feces. In order to do this, several stool smears must be made and carefully observed under the microscope. At this point, if the tests are positive, it will usually come down to three choices for a diagnosis. The choices being<unk> ,<unk>  histolytica, or<unk>  dispar. These three choices are, in the view of the microscope, "indistinguishable". This is the point where a doctor makes the call for what is most common<unk>  histolytica) or something more rare <unk> . If they choose to go with what is common, they will treat with "entamoebic chemotherapy". If the decision to treat amoebiasis is made, symptomatic or not, successful results may be reached using luminal agents. If the choice is to further examine the diagnosis, they will have to do a polymerase chain reaction. This is the only way to differentiate between the three amoebas and effectively diagnose.
