Understanding your covid19 spike protein antibody results

Sample: Blood test

Turn Around Time: 1 day  

Your COVID19 spike protein antibody results will be reported as a reference range: 

 

>= 50 AU/mL: this is a POSITIVE result for anti-SARS CoV-2s. 

A positive result means your body's immune system has generated a response to the COVID19 vaccine. It may also mean your body's system has generated a response to a prior COVID19 infection. 

The COVID19 spike protein antibody test is not able to differentiate whether the antibodies produced were in response to the vaccine or to a prior infection.

<= 50 AU/mL: this is a NEGATIVE result for anti-SARS CoV-2s. 

A negative result means your immune system has not generated a measurable response to the COVID19 vaccination and that you have likely not had the COVID19 infection.
