PCR test for corona virus suspicion or for screening; It involves swabbing the mouth and nose. Sampling is completed by gently inserting the same stick into the back of the mouth and then into the nostril. The samples are delivered to the laboratory in transport medium and the test phase is passed to detect the presence of the virus.

In the PCR test, samples are taken from two regions.

• Upper airways, including nasopharyngeal, nasal aspirate, nasal washing, oropharyngeal areas or saliva.

• Sample is taken for PCR test from the lower respiratory tract including sputum, bronchoalveolar lavage - BAL, tracheal aspirate.

The detection of corona virus with PCR test is defined 1-2 days before the onset of symptoms for respiratory samples in mild cases and continues for 8 days. In severe cases, the virus can be detected for a longer period of time. Viral RNA dispersion can be observed 1 month after infection in pediatric patients.

MobilePCR approved by the Ministry of Health is active in the mobilization phase of the PCR test. The samples it receives are delivered to authorized laboratories working in the covid-19 PCR Test in the microbiology departments of nearby and accredited hospitals. The result reached after the tests is published on e-Devlet.

The gene region is amplified in the PCR device and the products are electrophoresed together with the control product by applying electricity in gel medium. The weight of the control products is determined and the part reached by the PCR products is read based on the molecular weight, the test result is detected and reported as positive or negative.

A positive result means that you have been infected with the corona virus. People who get this result should be isolated, and at the same time, people with whom they had contact or had contact in the past should be scanned quickly. The isolation of infected people is important for public health.
