An evaluation of a lateral flow rapid diagnostic test for Strongyloides stercoralis infection.

Strongyloides stercoralis in humans often presents as a chronic asymptomatic infection. Diagnosis can be challenging due to the limited sensitivity of faecal-based parasitological techniques. A prototype lateral flow rapid diagnostic test (RDT) for the detection of specific antibodies against Strongyloides stercoralis (SsRapid) was evaluated using 143 samples from the serum bank of the Swiss Tropical and Public Health Institute. Group 1 (n=30) comprised serum samples from larvae-positive individuals; the RDT's diagnostic sensitivity was 97% (29/30). Group II comprised serum samples from patients with other parasitic infections (n=86) and Swiss blood donors (n=27); the RDT's diagnostic specificity for this group was 90% (102/113). The RDT showed good diagnostic performance and is a promising point-of-care test for detecting human Strongyloides stercoralis infection.

Déclaration de conflit d'intérêts

Declaration of competing interest Rahmah Noordin and Nor Suhada Anuar developed the Strongyloidesrapid test; thus, a conflict of interest may arise from its potential future commercialization. The other three authors (Beatrice Nickel, Christina Krebs, and Marie-Therese Ruf) do not have any conflict of interest.
