A new paper titled “Comparison between a rapid diagnostic test and dried blood spot-based immunoassay for hepatitis B surface antigen testing: Performance and cost implications in a population-based serosurvey in Vietnam” by Dr. Okawa et al. was published at International Journal of Infectious Diseases.
This study examined the agreement between a rapid diagnostic test (RDT) and a dried blood spot (DBS)-based electrochemiluminescence immunoassay (ECLIA) of hepatitis B surface antigen and compared the costs of conducting serosurveys using RDTs and DBS in a field setting. We found that the RDT and the DBS-based ECLIA had an almost perfect agreement with the HBsAg test results, and suggested that RDTs are a better option in terms of cost, whereas the DBS-based ECLIA may be useful when evaluating multiple infectious diseases.
