Antibodies are proteins produced by the immune system in response to an infection and are specific to that particular infection. They are found in the liquid part of blood specimens, which is called serum or plasma.

How is the COVID-19 Virus Detected using Real Time RT-PCR?

Mar 27, 2020·In order for a virus like the COVID-19 virus to be detected early in the body using real time RT–PCR, scientists need to convert the RNA to DNA. This is a process called ‘reverse transcription’. They do this because only DNA can be copied — or amplified — which is a key part of the real time RT–PCR process for detecting viruses.

Here we compare the performance of the Beckman-Coulter SARS-CoV-2 spike IgG assay to that of the Abbott SARS-CoV-2 nucleocapsid IgG and Roche Anti-SARS-CoV-2 nucleocapsid total antibody assays. In addition, we document the trend in nucleocapsid and spike antibodies in sequential samples collected from convalescent plasma donors.

Interpreting Diagnostic Tests for SARS-CoV-2 - JAMA

Synchronous seroconversion of IgG and IgM means SARS-CoV-2 is not a new virus for the patient because the IgG response needs about two weeks in response to new antigens. There are two possibilities: 1: SARS or another coronaviruses' surface antigens are the same as SARS-CoV-2 and so the antibody response is the same.
