ABSTRACT
Objective: There is a positive and significant relationship between severity and viral load in some viral diseases. Studies on the relationship between SARS-CoV-2 viral load at diagnosis and severity of coronavirus disease-2019 (COVID-19) have yielded conflicting results. Therefore, we aimed to evaluate the relationship between viral load and the clinical status of patients with COVID-19.Methods: Data of the patients diagnosed with COVID-19 and admitted to our center between May 01 and June 31, 2020, were retrospectively reviewed. The patients were divided into two groups according to their clinical character-istics as mild-moderate and severe. The demographic, laboratory, clinical, and radiological data were retrieved from electronic folders.Results: The entire cohort included 285 patients;254 had a mild-moderate clinical course, and 31 had a severe course. Statistical analyses revealed that SARS-CoV-2 viral load was not associated with symptom duration and clinical status (p>0.05). According to multivariate logistic regression analysis, only ferritin, C-reactive protein, and lactate dehydro-genase elevations were positively correlated with severe clinical course. (p<0.05).Conclusion: We do not recommend using viral load to predict disease severity in COVID-19. We also found that only ferritin, C-reactive protein, and lactate dehydrogenase accompanied severe clinical course. Keywords: cycle threshold, COVID-19, clinical severity

ABSTRACT
Shortly after the first cases were reported in late 2019 in Wuhan Province of China, SARS CoV 2 spread all over the world and was declared a pandemic by the World Health Organization on March 12, 2020. In Turkey the first case was in March 10, 2020 and March 25, 2020 in Duzce. Duzce University Faculty of Medicine, Department of Medical Microbiology, PCR laboratory was declared to be "T.C. Ministry of Health Duzce authorized Covid 19 PCR laboratory " in 28.03.2020. Samples are sent to our laboratory from all provincial and district hospitals, private hospitals and public health institutions in Duzce. This is the only Covid 19 center in our city and it works for 7 days a week. In our laboratory, Covid 19 antibody tests are carried out with card tests and ELISA methods. A total of 8500 COVID 19 PCR tests and 2200 anti Covid19 ELISA total antibody tests were studied in our laboratory within three months. Although covid 19 patients are not followed in our hospital, pandemic process continues in our laboratory. In addition, all PCR studies and IFA studies of the hospital are carried out in this laboratory.
