Statistically significant differences in FP rates were detected between clean negative samples and samples containing Leishmaniasis (P = 0.002) and ANA (P = 0.005), however the differences were small and unlikely to be clinically relevant (Leishmaniasis: mean difference = 1.67%, 95%CI: 0.63%– 2.71%; ANA: mean difference = 1.32%, 95%CI: 0.40%– 2.23%). The gene discussed is BTG3; the disease is leishmaniasis.
