Dried blood spot samples to be used for SARS-CoV-2 neutralizing antibody measurement

By using a minimally invasive finger prick, a dried blood spot (DBS) sample is obtained which is highly stable and easy to transport and store. NAB-Sure™, an ultrasensitive assay for anti-SARS-CoV-2 neutralizing antibody (NAb) can use DBS for serosurveillance of SARS-CoV-2. Discover how the sensitivity of NAB-Sure compares with that of other assays and explore how Spear Bio validates NAB-Sure DBS result accuracy by comparing to standard techniques.
