Refers to the detection of protozoal antibodies in the blood of E. histolytica in the human intestinal tract. The most reliable diagnosis of amebiasis is: direct smear microscopy of the smear of the amoeba (trophozoites or cysts) in the tissue, but misdiagnosis and missed diagnosis. Immunization test can make up for the deficiency of fecal microscopy. The clinical manifestations of amebiasis can vary greatly depending on the parasitic parts of the worm and the functional status of the host.

Clinical significance

The most reliable diagnosis of amebiasis is based on direct smear microscopy of the amoeba in the lysate (trophozoites or cysts), but misdiagnosis and missed diagnosis. Immunization test can make up for the deficiency of fecal microscopy. The clinical manifestations of amebiasis can vary greatly depending on the parasitic parts of the worm and the functional status of the host. The carrier (the worm body only colonizes the human intestine) does not have any clinical manifestations. When the worm invades the intestinal wall of the host and other tissues, it can produce a variety of clinical symptoms. The most common clinical types are amoebic dysentery and amoebic liver abscess. Positive in amebic liver abscess, intestinal amebiasis or worms.

Precautions

Fecal examination notes:

1, fresh, <1-2 hours.

2. Avoid drying the stool or contact with urine and water.

3. Insulation.

4. Stop antidiarrheals, antacids or antibiotics before bowel movements, or perform X-ray examination of tincture. For constipation, take magnesium sulfate or sodium sulfate.

Inspection process

For patients with chronic diarrhea, the capsule is mainly examined, and it can be stained with iodine solution to show the nucleus of the cyst, and differential diagnosis is performed at the same time. Precipitation of the capsule with formaldehyde ether can increase the detection rate by 40% to 50%. In addition, for some chronic patients, the fecal examination should last for 1 week to 3 weeks, multiple inspections to prevent missed diagnosis.
