Antibodies are part of the human body's immune response. They are developed for specific defense, e.g. against viruses.
An antibody test shows whether the body has already had contact with a certain virus and therefore gives a hint about an infection which was subsided.
The AProof® Coronavirus Antibodiy Test, developed in Leipzig, Germany, uses the ELISA assay method to detect IgG antibodies.
Developed in collaboration with the University of Leipzig and validated using samples from the LIFE-Projekt, the AProof® SARS-CoV-2 IgG ELISA is safe and effective. During the extensive validation, a sensitivity of 100% could be detected 14 days after the beginning of the desease. A very high specificity of 99.4% was demonstrated when testing more than 1,500 control samples.
Sensitivity describes the ability of a test to detect positive samples as being positive; specificity describes the ability of a test to detect negative samples as being negative.
