Are there deeper or more extensive tests to indicate this?
I ran across these on a keto blog site... No affiliation blah blah...
I believe that can be found via Labcorp (except the T-Detect test)
SARS-CoV-2 Semi-Quantitative Total Antibody, Spike
* This test will quantify the level of detectable antibodies against the SARS-CoV-2 spike protein receptor binding domain (RBD)
**Be sure to request the semi-quantitative as this will quantify how much antibody you have
SARS-CoV-2 Antibodies, Nucleocapsid
*Presence of nucleocapsid antibodies would indicate an adaptive immune response to SARSCoV-2, via recent or prior infection
T-DETECT: (this is ordered via www.t-detect.com but they use LabCorp as the draw site)
Cost is $199
*This test evaluates the specific T cell signature in response to SARS-CoV-2 infection,unfortunately it doesnt quantify the signature but does offer a positive or negative
