Pictor has received CE-IVD mark certification for its PictArray SARS-CoV-2 immunoglobulin G antibody test.

The assay detects if a patient has antibodies from a previous infection by the SARS-CoV-2 virus, based on viral spike protein and nucleocapsid protein antibodies, or from vaccination. It also indicates whether at-risk patients have failed to mount a detectable antibody response despite vaccination or infection.

Due to its ability to differentiate between natural and vaccine-based antibodies, the PictArray test could help in future vaccine development, the company said.
