|0.9 IV or less||Negative - No significant level of Strongyloides IgG antibody detected.|
|1.0 IV||Equivocal - The Strongyloides IgG antibody result is borderline and therefore inconclusive. Recommend retesting the patient in 2-4 weeks, if clinically indicated.|
|1.1 IV or greater||Positive - IgG antibodies to Strongyloides detected, which may suggest current or past infection.|
False-positive results may occur with prior exposure to other helminth infections. Testing low-prevalence populations may also result in false-positive results.
