#9550 Entamoeba histolytica IgG ELISA
ELISA kit for the diagnosis of human visceral amebiasis

Parasitology and clinical relevance

Fifty million people are suffering from extra-intestinal amebiasis in the world. It is responsible of fifty thousand death each year. It is the second cause of mortality by parasitic infections, after Malaria. Patients become infected when eating contaminated vegetables or water. The disease is confirmed by microscopy when the hematophagous form of Entamoeba histolytica are detected in stool samples. However this vegetative form are frequently absent or present in very small numbers. Therefore, a serological assay to detect infection of E. histolytica is a useful complement to parasitological tests. The diagnosis of human amebiasis using the ELISA kit is intended for travellers returning from endemic areas and developing symptoms like abdominal pain, fever and hepatomegaly and to post therapeutic controls.


96 determinations of IgG antibodies using standard methodologies.

Wells sensitized with soluble trophozoite antigens from Entamoeba histolytica.

8-wells polystyrene breakable strips: useful and economic format for laboratories with a small workload.

CE registration: CH-201202-0033

Sensitivity and specificity

The test detects Entamoeba histolytica extra-intestinal infections.

A sensitivity of 100% was found with 52 sera from patients with clinically proven Entamoeba histolytica extra-intestinal infection.

A specificity of 89% was found with 71 sera from amebiasis suspected patients but where this disease had been certainly ruled out.

A specificity of 96% was found with 99 sera of blood donors.

A specificity of 80% was found with 40 sera from patients with other parasitc infections.
