In this study we see Dried blood spot (DBS) tests can be utilized for the location of serious intense respiratory disorder Covid 2 spike antibodies. DBS testing is equivalent to coordinated with serum tests with a general 98.1% affectability and 100% explicitness. In this manner, DBS examining offers an option for populace wide serologic testing in the Covid pandemic. An affirmed determination of intense Covid infection (COVID-19) relies upon the identification of RNA from the causative microbe, extreme intense respiratory condition Covid 2 (SARS-CoV-2). Interestingly, albeit serologic testing is less valuable for diagnosing the intense phases of contamination, it can help in diagnosing abnormal signs of SARS-CoV-2 disease and in deciding earlier infection openness at a populace level (1), information which could considerably impact general wellbeing and social approaches.

At present, neutralizer testing for SARS-CoV-2 uses serum or plasma gathered by venipuncture. It is a grounded technique for distinguishing antibodies against different diseases (5,6), and antibodies gathered by DBS are steady for delayed periods. Additionally, DBS examining gives an answer for enlarging admittance to serologic stages in low-and center pay nations. We portray the approval of DBS tests against coordinated with serum in an exceptionally touchy and explicit SARS-CoV-2 ELISA.
