Investigation of COVID-19 Serology in a Tertiary Care Center

Purpose: This study aimed to screen the patients admitted our hospital for SARS-CoV-2 specific antibodies after a PCR test and understand local serological profile.
 Materials Methods: The patients, that were tested anti-SARS-CoV-2 IgG and/or IgM between January-June 2021 included in study. was performed simultaneously.
 Results: Either or alone requested 123 of 725 together 602. positive 40 (13%) 304 (42%) who had 30 days serology request. Of these 60% together, whereas among 204 negative 64% IgG. 58% tests ordered without period testing as follows: 233 (76.6%) 7 days, 27 (8.8%) 8-14 (2.3%) 15-21 37 (12.3%) 22-30 days. 117 (38.5%) requests done Conclusion: WHO recommends should be 1st 3-4th week initial test. high rate inappropriate demonstrates lack algorithms. Use is recommended conjunction with nucleic acid tests, but not used diagnosis COVID-19. Our results demonstrated unnecessary determine antibody response against vaccines.
