- Ref. Range Notes
Reference Range: Negative Interpretation:
Negative: No detectable levels of IgG antibodies to Strongyloides. Repeat testing in 10 to 14 days if clinically indicated. Positive: IgG antibodies to Strongyloides were detected, suggesting current or past infection. False-positive results may occur with other helminth infections (e.g., Trichinella, Taenia solium). Clinical correlation is required. - Interferences and Limitations
Cautions:
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.
The seroprevalence of IgG-class antibodies to Strongyloides stercoralis ranges from 0% to 6.1% in the United States.
