1.0 mL Serum in a SST Gold Top Tube 

Negative

Reference values apply to all ages.

INTERPRETATION 

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.

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.
