A molecular biology report for a patient named Mohammed Shazin shows that a SARS-CoV-2 test of his nasopharyngeal/oropharyngeal swab sample returned a negative result. The test used was a qualitative real-time polymerase chain reaction (RT-PCR) test intended to detect the novel coronavirus responsible for COVID-19. A negative result means that SARS-CoV-2 was not detected in the given specimen but does not rule out infection, as the test can return false negatives. The interpretation guidance notes that a single negative test does not exclude infection and recommends repeat sampling and testing of lower respiratory specimens for severe or progressive disease.
