Evaluation of Two Commonly Used Commercial Immunochromatographic and ELISA Screening Kits for the Detection of Anti-HCV Antibodies among Patients in North Central Nigeria (original) (raw)

British Journal of Medicine and Medical Research, 2014

Abstract

Background: Hepatitis C Virus infection presents a major public health threat globally. The advent of different immunoassays for the detection of specific markers for the diagnosis of the infection since the discovery of the virus is a positive development, but their varied degrees of sensitivity and specificity is a matter of public health concern. Aim: To evaluate the efficiency of two commercial rapid test kits for the detection of antiHCV antibodies against a third generation Enzyme Immunoassay (EIA) used as a gold standard. Methodology: A total of 500 patient plasma samples screened by ELISA (Autobio Diagnostics, China) were subjected to further screening using two rapid test (immuno chromatographic) strips supplied by Global Diagnostics (USA) and Wondfo Biotech Diagnostic Products (China). Results: Of the 500 samples, anti HCV was detected in 79(15.80%) by ELISA, 59(11.80%) by Wondfo strip, whereas only 45(9.00%) by Global strip method. This gave Wondfo Kit a sensitivity of 75.0%, specificity of 99.0%, overall accuracy of 95.2%, positive predictive value of 93.6%, negative predictive value of 95.4% positive likelihood
