Amoebic Dysentery - Diagnosis
The best diagnosis is by demonstrating cysts or trophozoites in a stool sample.
1. Stool tests
- Three stool samples should be done in the laboratory to confirm the presence of E. histolytica.
2. Blood tests
- There are many blood tests that can be done for diagnosis having a high degree of accuracy.
3. Proctosigmoidoscopy or Colonoscopy
- These are special procedures done when the diagnosis is not clear after stool and blood tests.
- This involves the use of a thin, lighted instrument inserted into the rectum and colon to view them directly and tissue samples are taken for laboratory examination.
- If there are complications and involvement of the abdominal organs, then further investigations, such as ultrasound, may be necessary to confirm the diagnosis.
