Amplification of both targets results in a presumptive positive (detectable) test result, while amplification of one of two targets results in an inconclusive result, and amplification of neither RT-PCR: Real-time RT–PCR is one of the most commonly used laboratory methods for the detection of the COVID-19 virus. Most tests to screen for current SARS-CoV-2 infection depend on RT-PCR tests to identify the RNA virus in a patient’s respiratory tract sample. COVID-19 PCR Assay Real-Time PCR Assays for SARS-CoV-2 Pathogen Detection Direct pathogen determination via Real-Time RT-PCR is the method of choice to detect acute COVID-19 infections. 1 Refer to The Use of Alternate Sample Collection Methods for COVID-19 PCR Testing document for further information on alternate specimen types. 2 See Specimen Collection Kits and Instructions Table below for which kit is also suitable for Rapid Flu testing and seasonal respiratory multiplex testing.

Prof. Teshima warns of such trends and hopes that the improved accessibility to PCR testing will be the key to dispelling these concerns.
Has Spain's management of COVID-19 been a failure? Errors
In this study, we aim to review and analyse current literature to compare RT-PCR, immunological biomarkers, chest radiographs, ultrasound and chest CT scanning as methods of diagnosing COVID-19. In-house real-time reverse transcription polymerase chain reaction (RT-PCR) test methods targeting SARS-CoV-2 viral RNA are the gold standard in vitro methods for diagnosing suspected cases of COVID-19.
The test reads the presence of virus Ribonucleic Acid (RNA) in a
COVID-19 can be identified with higher precision using CT than with RT-PCR. Subpleural dominance, crazy paving, and consolidation may develop as the disease evolves. Chest CT scans and chest x-rays are not recommended for diagnosing COVID-19.

After that, the virus is extracted and tested using the PCR method to see if Covid-19 is present. At Siloam, the testing is done using four PCR machines owned by MRIN.
Här kan du även ta PCR-test. A PCR test for COVID-19 is a test used to diagnosis people who are currently infected with SARS-CoV-2, which is the coronavirus that causes COVID-19. The PCR test is the “gold standard” test for diagnosing COVID-19 because it’s the most accurate and reliable test. Who should get tested for COVID-19? Real time RT–PCR is one of the most widely used laboratory methods for detecting the COVID-19 virus.
