COVID-19 antibodies were found in 75 percent of serosurvey participants from five slums in Mumbai's Cuffe Parade
The report suggests that most seropositive participants were either asymptomatic carriers or unwilling to share information about an earlier COVID-19 infection.
The findings could have implications in testing, undermining results from tests that look for antibodies to certain proteins of the virus.
Experts have said these findings are not unexpected, since other viral illnesses also trigger 'autoantibodies'.
Study reveals new test, IP-FCM, could be used to detect COVID-19 antibodies, their effectivity against the novel coronavirus
For this study, the scientists collected blood samples of 24 patients who tested positive for COVID-19 infection, presented with mild to moderate disease and were not hospitalised. Out of these 24, 12 patients experienced fever while 16 experienced cough
Antibodies indicates previous exposure, may not guarantee protection against COVID-19, say scientists
Though a number of studies have been conducted, information as to the type and level of antibodies is limited, scientists said
