A Nasal Complication of Nasopharyngeal Swab for Reverse Transcription Polymerase Chain Reaction (RT-PCR) Detection of SARS-CoV-2 mRNA

Abstract

Nasopharyngeal (NP) and oropharyngeal (OP) specimens in the detection of the SARS-Cov-2 RNA are considered to have the highest diagnostic sensitivity and they have been recommended by the World Health Organization as the most reliable test. However, collecting NP specimens require specialized operators and adequate technique. We describe an intranasal breaking of the nasopharyngeal swab for anatomical reasons needing a surgical removing. We conclude that a safely procedure needs possibly a check for septal deviations or other causes of nasal obstruction.
