Currently available strongyloides diagnostic studies.

Diagnostic test	Sensitivity/specificity	Advantages	Disadvantages
Stool smear Baermann [20]	75%	Easily obtained	Requires multiple specimens to improve sensitivity and specificity
ELISA IgG [21]	97% sensitivity 95% specificity	High sensitivity High specificity	False negatives Other filarial reactions can cause false positivity Remains positive for extended periods even after treatment
Stool on Agar plate culture [1, 22]	96% sensitivity	High sensitivity	Requires at least 2 days
PCR [23, 24]	>95% sensitivity >95% specificity	High specificity Becomes negative after successful treatment	Not all diagnostic centers are equipped to perform test
Luciferous immunoprecipitation System [21]	97% sensitivity 100% specificity	<2.5 hours High sensitivity and Specificity Seroconversion after treatment	Not all labs have capability to perform test
