# 9450 Strongyloïdes ratti IgG ELISA
ELISA kit for the diagnosis of human strongyloidiasis

Parasitology and clinical relevance

Strongyloides stercoralis is a potentially dangerous parasite, particularly if unsuspected and present in immunocompromised patients or in patients receiving immunosuppressive drugs. An hyperinfection syndrome can occur with widespread nematode dissemination and a high mortality. Parasitological diagnosis is often time- consuming as Strongyloides larvae in the stool are frequently absent or present in very small numbers. Therefore, a serological assay to detect infection with Strongyloides is useful. Our ELISA uses the structural similarities existing between S. stercoralis and S. ratti antigens to detect antibodies in human sera.


96 determinations of IgG antibodies using standard methodologies.

Wells sensitized with somatic antigens from larvae of Strongyloïdes ratti.

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

CE registration: H-CH/CA01/IVD/10285

Sensitivity and specificity

Sensitivity of 88% with sera from patients with larvae of Strongyloides stercoralis.

Specificity of 94% with sera of blood donors (from Switzerland).

Specificity of 77% with sera of patients with other parasitoses (mostly helminthiases).
