摘要：

Diluted dried blood drops on filter paper were compared with serum samples as a specimen source for qualitative anti-HAV antibody determination by ELISA. A total of 298 serum samples and dried blood drops were collected from a population of healthy adolescents (153 +/- 1.2 years old). The prevalence of anti-HAV antibody obtained by testing serum samples was 7.7 % (95 % CI: 4.8-10.1). Compared with serum sampling the sensitivity and specificity of diluted dried blood drops were 91.3 and 99.3 %. The positive and negative predictive values were 91.3 and 99.3 %, respectively, and the likelihood ratios of positive and negative results were 91 and 0.09. It is proposed that this test represents a reliable procedure for anti-HAV antibody testing.
