Screen for the presence of IgG-class antibodies to Strongyloides
This test may be used as a screen to determine exposure status to Strongyloides.
This assay detects IgG-class antibodies only.
This assay should not be used to monitor patient response to therapy as IgG-class antibodies to Strongyloides may remain detectable following resolution of infection.
False-positive results may occur with other helminth infections, including prior exposure to Entamoeba histolytica, Ascaris, Taenia solium, Fasciola species, Echinococcus species, Schistosoma species, and Toxocara (per assay manufacturer).
This assay should not be used alone to establish a diagnosis of strongyloidiasis. Results should be correlated with other laboratory findings and through clinical evaluation.
False-negative results may occur during acute or localized infection. A single negative result should not be used to rule-out infection.
This assay should not be used to monitor response to therapy.
The seroprevalence of IgG-class antibodies to Strongyloides stercoralis ranges from 0 to 6.1% in the United States.
Positive: IgG antibodies to Strongyloides were detected, suggesting current or past infection. False-positive results may occur with other helminth infections (eg, Trichinella, Taenia solium). Clinical correlation is required.
Negative: No detectable levels of IgG antibodies to Strongyloides. Repeat testing in 10 to 14 days if clinically indicated.
