COVID-19 Antibody Test (ELISA) for Those Already Infected With Coronavirus

By Jonathan Mintz

Researchers at the Mount Sinai Wellbeing System say they have designed a check that can discover out if you already have experienced or were being infected with the new coronavirus.

The check is known as “serological enzyme-linked immunosorbent assay,” or ELISA for limited. It checks whether or not you have antibodies in your blood to SARS-CoV-2, the scientific title of the new coronavirus that causes COVID-19.

Researchers say ELISA performs like antibody exams for other viruses, these types of as hepatitis B. It will show whether your immune system — the body’s protection versus germs — built make contact with with SARS-CoV-2, even months just before.

The check could assist experts battle the pandemic in numerous strategies. It can give researchers a additional accurate measure of how a lot of people today experienced the new coronavirus. It would also allow health care employees who were being ill with COVID-19 indications, but were being under no circumstances examined for the condition, return to do the job — self-confident that they are now immune.

The check could also assist with an experimental treatment method for COVID-19 known as convalescent plasma. In this remedy, medical doctors acquire blood from people today who have recovered from the condition. Researchers hope antibodies in the blood can take care of people today with COVID-19. The ELISA check could assist establish people today with antibodies who could be in a position to donate their blood.

The Fda is encouraging researchers to start out medical trials on convalescent plasma. But for the reason that of the pandemic, it states some medical doctors may be supplied permission to use the strategy in everyday living-threatening instances.
