CONCLUSION
Recent experiences at our hospitals suggest that despite high
specificity of RT-PCR for SARS-CoV-2, positive screening tests in the
absence of other symptoms or classic findings of the disease should be
rigorously verified before urgent care is delayed. It is a disservice to
our patients not to remain vigilant to possible false positive tests as
the resultant clinical implications can jeopardize the safety of our
patients. We recommend a multidisciplinary approach for investigation,
including re-evaluation of RT-PCR titers by pathologists, repeating
RT-PCR on a different testing platform, and obtaining a CT of the chest,
particularly for patients who do not have other chest pathology. Testing
for immunoglobulins specific for SARS-CoV-2 antigens was not yet widely
available at the time of these interventions, but this may prove useful
as it becomes more readily available.
