ABSTRACT

A 71-year-old male patient presented to his local doctor with fever, cough and diarrhea. He was suspected to have coronavirus infectious disease 2019 (COVID-19) pneumonia. Severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) polymerase chain reaction (PCR) tests of nasal swabs were performed twice, but both tests were negative. He came to our hospital because of worsening pneumonia. PCR tests were further performed twice, and an antigen test of nasal swabs, and all were negative. Since COVID-19 pneumonia was strongly suspected from blood tests and shadows, we performed a bronchoscopy, and on PCR, bronchial lavage fluid was positive. If COVID-19 pneumonia is suspected, a lower respiratory specimen should be considered, even if the upper respiratory specimen is negative.
