“The sensitivity of the PCR method is 70–80%. We have patients with negative test results, but they have COVID-19 disease, ”the specialist said, making a report on the main mistakes in routing patients with community-acquired pneumonia.
He referred to the results of a study involving 1.4 thousand patients. 300 of them had a negative laboratory test for SARS-CoV-2, but the results of computed tomography of the lungs showed changes characteristic of a new coronavirus infection.
“Thus, the most sensitive test for the diagnosis of patients with COVID-19 is computed tomography of the lungs. The sensitivity of CT methods is higher than the PCR diagnostic methods, ”the expert emphasized.
Earlier, the Ministry of Health said that all hospitalized patients with pneumonia are required to be examined for coronavirus infection, including laboratory tests using test systems. Data is entered by medical organizations into the information system integrated into the EHISP.
