Inconclusive result, which may occur early in the infection or
could be non-specific.
An increase in antibody level can support a diagnosis of Covid-19.
Consider repeat testing in 14 days if confirmation of infection or exposure to COVID 19 is suspected

Any result should not affect compliance with personal
protection guidelines.

Positive - SARS-CoV-2 IgG antibodies: Positive by EIA (Abbott)
Consistent with current or previous Covid-19 infection.
Please Note result DOES NOT indicate immunity from future
infection or prevent current or future excretion of the
virus (infectivity).

protection guidelines.
