Duzce COVID 19 PCR Tests are Worked How, Where and Under Which Conditions?

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 Covid 19 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.WOS:00058856330000

Evaluation of Quality Assurance Indicators and Contamination Rate in Blood Culture

Objective: Blood culture are of vital importance in patient follow-up, as they enable the identification and production of sepsis causative microorganisms, initiate antibiotic treatment in a timely manner and reduce mortality and morbidity. In this study, it is aimed to evaluate the microorganisms grown in the automated blood culture in the microbiology laboratory of the hospital in terms of quality indicators. Methods: In this study, microorganisms grown from automated blood culture BACTEC-9120 (Becton Dickinson, USA) system from the blood culture samples sent to Duzce University Medical Microbiology Laboratory were evaluated retrospectively. For this purpose, the rejection and contamination rate of the samples for which blood culture was requested, the result of Gram staining-final identification compliance, the number of samples sent from a single bottle, and the growth times of microorganisms after incubation were determined. Results: 5037 blood culture samples were sent to the laboratory from various clinics. 1.7% of these samples were rejected as inappropriate samples. Gram stain-final identification compatibility of blood cultures was investigated and it was determined as 97.8%. The single bottle number of the samples sent was found to be 511. For the 5037 samples included in the study, growth was detected in 20.7%, of which 10.2% were considered as contaminants In our study, the average breeding time of the factors examined for breeding time was determined to be 30.29 hours. Conclusions: As conclusion, there is no gold standard to distinguish true pathogens from contaminant agents in blood cultures.WOS:00070904020001
