However in results, the authors have mentioned that only 112 out of 173 participants tested positive for RNA over complete duration of the study, which contradicts the methodology. Third, Antibody tests in this study population should be interpreted cautiously since 1) there is plausibility to have cross reaction to antibodies related to other corona virus strains and 2) also diseases caused by other corona virus present with similar symptoms as COVID-19, and symptomatic patients might have antibodies which may lead to increased false positivity rate. Therefore present study should carefully interpret the serological tests and sensitivity should be calculated only in participants tested positive for RNA.
