RE: Antibody testing hasn’t gone away12 Jul 2021 22:01
The question I now have about ABC-19 is around how clinically valuable the data is. I supported the product all the way through but now have more questions which make me wonder if I was a little naive.
How valuable is a qualitative result? ABC-19 is a qualitative (yes/no) test so can't be used to determine level if immune response.
Does the presence of antibodies really mean anything when organisations and countries are still more interested In whether you are carrying the virus? (Antibodies present or not) maybe valuable as a research tool.
Does the presence of antibodies matter in the face of variants and the ongoing threat of generating immune escape variants? Ie antibodies could be detected but they offer no protection against different variants.
I dont think we will see a positive antibody test granting freedoms any time soon. That will still be determined by antigen testing.
