A new rapid serology, self-contained assay uses "lab at your fingertip" technology to accurately measure the presence of SARS-CoV-2 antibodies in 15 minutes with no buffers, reagents, or additional equipment.

The ADEXUSDx COVID-19 antibody test from NOWDiagnostics, Inc. (Springdale, AR, USA) is a rapid serology, self-contained assay that measures the presence of SARS-CoV-2 antibodies and delivers lab-quality results in 15 minutes with no buffers, reagents, or additional equipment. The test requires only a drop of blood (either capillary blood from a simple fingerstick or 40 μL of venous whole blood, serum, or plasma) and has the potential to be deployed directly into homes and workplaces. The ADEXUSDx COVID-19 antibody test can be used across a variety of health care settings - from hospital emergency rooms to clinics - and ultimately, by consumers for at-home use.

The innovative diagnostic device delivered 100% sensitivity and 100% specificity in a well-characterized 45 sample panel of COVID-19 positive and negative patient samples, and was filed for Emergency Use Authorization (EUA) from the US Food and Drug Administration (FDA). If FDA authorizes emergency use, the ADEXUSDx COVID-19 Test will become available for use in CLIA-certified laboratories across a variety of health care settings from clinics to hospital emergency rooms in the US.
