A Serological Assay to Detect SARS-CoV-2 Antibodies in at-Home Collected Finger-Prick Dried Blood Spots

Keywords (Tags): testing

A home-based finger‐prick dried blood spot collection kit demonstrated 100% sensitivity and 100% specificity in detecting SARS-CoV-2 antibodies against S1 protein in 111 specimens collected at home from 31 patients with COVID-19 and 80 healthy participants. The authors conclude such methods may facilitate the test within hard-to reach-populations and help reduce the sample collection burden of serological testing on both health care systems and individuals.
