Antibody ELISA test


The most precise and sensitive SARS-CoV-2 antibody test

Using an enzyme-linked immunosorbent assay (ELISA) and a blood sample from a person, it is possible to detect for the presence of antibodies against SARS-CoV-2, the virus behind COVID-19.

At PentaBase we always strive to use the best scientific solution for a problem. For the ELISA studies we are therefore using the ELISA method found to be the most precise and sensitive among nine assays Evaluated by SSI, Rigshospitalet and RUC (Denmark).

PentaBase is putting high pride in the scientific correctness and is always using assays of the highest quality.

The assay is carried out in a 96-well plate coated with a SARS-CoV-2 specific protein. The human body normally produces antibodies against this protein during an infection with SARS-CoV-2. Plasma or serum from a blood sample is then added to the protein coated wells under conditions allowing for the specific binding of potential antibodies to the protein. Unbound material is washed away.

A color reaction is then added to the reaction, validating if specific antibodies are bound to the plate or not. If the sample is positive, the well turns yellow.

Antibodies against SARS-CoV-2 indicates that the person has been or is currently infected with SARS-CoV-2 virus known for causing COVID-19. 
Normally, antibodies against a disease-causing microorganism/virus will confer full or partly protection against the disease over a period of years.

For a person to be called positive for SARS-Cov- antibodies,
three quantitative photometric measurements should all be above threshold. Furthermore, we confirm positive results by visual inspection by at least two scientists
