Based on the bivariate random-effects model, the pooled sensitivity and specificity of DBS-based HBsAg testing were 0.943 (95\u202f% CI, 0.916\u20130.962) and 0.988 (95\u202f% CI, 0.980\u20130.993), respectively, with a pooled DOR of 1,995.07 (95\u202f% CI, 834.68\u20134,768.66). The pooled sensitivity and specificity were 0.836 (95\u202f% CI, 0.737\u20130.902) and 0.973 (95\u202f% CI, 0.937\u20130.989) for DBS-based anti-HBc testing, and 0.869 (95\u202f% CI, 0.787\u20130.922) and 0.963 (95\u202f% CI, 0.932\u20130.980) for DBS-based HBV DNA testing, respectively.
