Abstract
INTRODUCTION: Hepatitis B viral infection is a global health issue. Various screening and confirmatory serological tests have evolved in the past few decades for detection of hepatitis B. However, oral fluid as an alternative to blood could provide substantial advantages. The study aimed to evaluate the diagnostic efficacy of oral fluid in detecting hepatitis B surface antigen using Enzyme Linked Immunosorbent Assay (ELISA). MATERIALS AND METHODS: Salivary and blood samples were collected from 40 seropositive and 40 seronegative patients of hepatitis B viral infection and were subjected to ELISA test for hepatitis B surface antigen. Mann-Whitney U test was used to test the statistical significance and Kappa (K) statistic was used to assess the degree of agreement between serum and oral fluid samples. The p-value <0.05 was considered as significant value. RESULT: A sensitivity and specificity of 100% of oral fluid assay was obtained for the diagnosis of hepatitis B infection. The degree of agreement between saliva and serum for detection of hepatitis B was found to be perfect (Kappa value =1). CONCLUSION: Oral fluid testing can be an interesting, alternative for hepatitis B infection for diagnosis and screening for epidemiological purposes. Further research necessitates for the implementation of saliva as a diagnostic tool.
