The Importance of Molecular and Clinical Laboratory Tests in Diagnosis and Treatment of Coronavirus Disease

900 abusers were tested for the presence of drug abuse and coronavirus disease. In the early stage, the throat and noise samples of these patients were examined by polymerase chain reaction (PCR). The mean age of the study group is 42±23. Hematological and serological examinations were performed on 131 patients. All data were analyzed by t-test and one-way analysis of variance (ANOVA). Therefore, P < 0.05 is considered as the significance of the test results. The results showed that 131 patients in the study group had positive results of PCR tests and nearby they had Covid-19. Approximately 90% of patients with coronavirus disease showed positive serological tests and lymphopenic condition. All of urine or blood samples in the 131 patients were positive for the presence of abuse drugs. C-reactive protein (CRP) is one of important serologic test that detected on these patients. This study showed the importance of molecular genetics test such as PCR and also hematology and serology tests in distinguish of coronavirus diseases.
