Objective: Introduction: A novel coronavirus SARS-CoV-2 RNA, detected by reverse-transcription polymerase chain reaction (RT-PCR) was identified as the cause of a cluster of pneumonia cases in Wuhan, China. It rapidly spread, at first in China, then resulting in an epidemic in other countries throughout the world. One of such controversial topics is the issue of diagnostics and interpretation of test for COVID-19. According to Polish and global guidelines, the basis for diagnosis is molecular testing - real-time reverse transcriptasepolymerase chain reaction (RT-PCR). Taking all these data into consideration, the aim of the study was to compare RT-PCR with serological test in our employees post-exposure. According to Polish and global guidelines, the basis for diagnosis is molecular testing, real-time reverse transcriptase-polymerase chain reaction (RT-PCR). The aim: To compare RT-PCR with serological test in our employees post-exposure., Patients and Methods: Material and methods: 79 employees of the Clinic, 19 men and 60 women in the age range 27-69 years were evaluated. Tests were begun four days after information about the positive test in our "Employee 0" and lasted for 7 days. At first, we made RT-PCR tests on the specimen from nasopharyngeal swab. Then, we accomplished rapid antibodies tests. This test is based on the qualitative assessment of the presence of IgM and IgG antibodies by immunochromatography using a sample of capillary blood from the fingertip., Results: Results: All the tests were negative. No employee developed symptoms during the 7-day follow-up after the end of the tests., Conclusion: Conclusions: As routine tests for patients have been implemented widely, but similar solutions for employees have not gained popularity. Use of personal protective equipment (PPE) e.g. facemask and shields, transparent screens, disposable medical uniforms, minimalization the contact time, increasing distance from both colleagues and patients (if possible), and strictly follow sanitary procedures largely contributed to the absence of illness in the surveyed group of employees.
