Laboratory Findings
- Fecal leukocytes and occult blood : The ability of these tests to diagnose the presence of dysentery is variable
- Fecal lactoferrin : Lactoferrin is a marker for fecal leukocytes and has sensitivity and specificity ranging from 90 to 100 percent in distinguishing inflammatory diarrhea from noninflammatory causes. This test is not widely used.
- Cultures of stool samples are examined in order to identify the organism causing dysentery. Usually, several samples must be obtained due to the changing number of amoeba, which changes daily.
- Blood tests can be used to measure abnormalities in the levels of essential minerals and salts.
