How is dysentery diagnosed?
Dysentery and its cause can only be determined by microbial testing in a laboratory. To test for the cause of dysentery, a stool sample is usually required for analysis from the patient. For Amoebic dysentery, Entamoeba histolytica needs to be identified in the sample to diagnose it as such. The culture of the stool is usually made for testing for bacterial dysentery. If the growth of bacteria that cause dysentery is seen, then it can be diagnosed as bacterial dysentery. Serologic tests such as Enzyme-linked immunosorbent assay (ELISA) may also be needed if the extraintestinal disease is suspected.
