Another diagnostic testing kit was developed by Gonoshasthaya Kendra, Bangladesh on 17 March 2020. This cost-effective kit (only $3.25 to produce) named ‘Gonoshasthaya Rapid Dot Blot’ can test antigen as well as antibody using saliva and swab samples and yields results within 15 minutes. The team led by Dr. Bijon Kumar Sil had been waiting for approval from the Directorate General of Drug Administration (DGDA) to use their kit immediately [54, 55]. In recent clinical trials, the Gonoshasthay’s kit has shown 97.7% sensitivity and 96% specificity in internal validation that satisfies the US FDA guidelines for antibody testing kits [56].
