The rK39 test is a serologic assay for the rapid diagnosis of visceral leishmaniasis (VL). Serum from a North American cohort of 59 otherwise asymptomatic soldiers with cutaneous leishmaniasis (CL) was tested with the rK39 dipstick and ELISA assays, and 10.2% and 28.8% had positive results, respectively. CL is associated with a reactive rK39 assay result in some patients without clinical evidence of VL.
