Pre-Procedural Antibody Testing for SARS-CoV-2 in routine endoscopic practice.

Retrospective multicentre cohort study of all endoscopic procedures performed between 4/27 and 6/15-2020. A screening questionnaire(SQ) was run to the patients 3 days prior to the procedure and 14 days after. Also, a serologic SARS-CoV-2 test was performed 48 hours before. RESULTS: 211 consecutive patients with endoscopic procedures were included. No patients with a positive initial or 14 days later SQ. Only 4 patients had antibody positives, 1.9%(IC 95%:0.07-4.8%). CONCLUSION: The pre-endoscopy seroprevalence of SARS-CoV-2 is low in this cohort. The Pre-Procedural SARS-CoV-2 Antibody Testing does not add any benefits over clinical SQ in order to identify active COVID-19 patients.
