Chronic infections of humans with Opisthorchis viverrini and Clonorchis sinensis spanning decades may lead to life-threatening pathology prior to cholangiocarcinoma (CCA), which usually has a poor prognosis. Serological tools can support the parasitological examination in clinical diagnosis and support screening for risk of CCA. We developed novel immunochromatographic test kits using a soluble, somatic tissue extract of adult O. viverrini worms as an antigen and colloidal-gold labeled conjugates of IgG and IgG4 antibodies and evaluated the diagnostic values of both the OvSO-IgG and OvSO-IgG4 kits. For diagnosis of human opisthorchiasis individually, the diagnostic sensitivity, specificity, positive and negative predictive values with 95% confidence intervals in the OvSO-IgG kit were 86.6% (78.9-92.3), 89.5% (84.2-93.5), 82.9% (74.8-89.2), and 91.9% (87.0-95.4), respectively, while the 75% (65.9-82.7), 98.4% (95.5-99.7), 96.6% (90.3-99.3), and 87% (81.7-91.2), respectively, for the OvSO-IgG4 kit at the prevalence of infection of 37.1%. Twenty-three (76.7%) and 14 (46.7%) of 30 clonorchiasis sera showed positive reactivity with the OvSO-IgG and OvSO-IgG4 kits, respectively. There was 84.1% (κ-value = 0.649) concordance between the two kits, which was statistically significant (p < 0.001). Both ICT kits can be employed as quick and easy point-of-care diagnostic tools, and hence the OvSO-IgG and OvSO-IgG4 kits can support expanded capacity for clinical diagnosis of human opisthorchiasis and clonorchiasis. These kits may find utility in large-scale surveys in endemic areas where there are limited sophisticated medical facilities or capacity.
