Effect evaluation of three ELISA kits in detection of fasciolasis

OBJECTIVE: To evaluate the effect of 3 ELISA kits on detection of human fasciolasis. METHODS: Twenty-six serum samples from patients with fasciolasis, 180 serum samples from patients with other parasitic diseases as well as 26 serum samples from healthy people were detected by ELISA kits which using soluble antigen of Fasciola gigantica, Fasciola hepatica (Fg-ELISA and Fh-ELISA) as well as IgG antigen ELISA detection kits made by DRG company in Germany. The effects of the 3 kits were evaluated. RESULTS: The sensitivities of Fg-ELISA, Fh-ELISA, and DRG-ELISA were 100.0%, 80.8% (95% CI: 65.7%-95.9%) and 100.0%, respectively; the specificities of the three were 87.9% (95% CI: 83.5%-92.4%), 85.0%(95% CI: 80.1%-89.9%) and 83.5% (95% CI: 78.4%-88.6%), respectively, and Youden indexes of them were 0.88, 0.66 and 0.84, respectively. The detection rate of Fg-ELISA (100%) was significantly higher than that of Fh-ELISA (80.8%) (P < 0.05). The A absolute value (A/CO) of Fg-ELISA was 1.70, which was also significantly higher than the value of Fh-ELISA (1.18) (P < 0.000 1). CONCLUSION: Fg-ELISA has a good detection effect and low cost, and is more suitable than Fh-ELISA and DRG-ELISA for clinical sample tests as well as massive screening in fasciolasis endemic areas in southwest China.
