Interpretation:

SARS-CoV-2-IgG Index <1.4:  Negative

Negative results do not rule out SARS-CoV-2 infection, particularly in those who have been in contact with the virus. Follow-up testing with a molecular diagnostic should be considered to rule out infection in these individuals. 

 

SARS-CoV-2-IgG Index >1.4:  Positive

Positive results may be due to past or present infection with non-ARS-CoV2 coronavirus strains, such as coronovirus HKU1,NL63, OC43, or 229E

 

 

Reference values apply to all ages.
 

For use under FDA Emergency Authorization Only. Results from antibody testing should be used in conjunction with information available from clinical evaluation and other diagnostic procedures.
