Correlation of chest CT and RT-PCR testing in coronavirus disease 2019 (COVID-19) in Turkey
Aim: Chest CT plays an important role in the treatment and diagnosis of COVID-19. It is important to remember that patients with RT-PCR test positive for COVID-19 infection may have normal chest CT.

Detection of 2019 novel coronavirus (2019-nCoV) by real-time RT-PCR
Background The ongoing outbreak of the recently emerged novel coronavirus (2019-nCoV) poses a challenge for public health laboratories as virus isolates are unavailable while there is growing evidence that the outbreak is more widespread than initially ...

Sensitivity of Chest CT for COVID-19: Comparison to RT-PCR
In a series of 51 patients with chest CT and real-time polymerase chain reaction assay (RT-PCR) performed within 3 days, the sensitivity of CT for 2019 novel coronavirus infection was 98% and that ...

SARS-CoV-2 RT-PCR positivity rate and predictor factors for RT-PCR results in COVID-19 disease
Background/Aim: In December 2019, a novel coronavirus was identified and caused the SARS-CoV-2 (COVID-19) pandemic. The gold standard diagnostic method is the detection of nucleic acid in respiratory tract samples by real-time polymerase chain reaction ...

Chest CT for Typical 2019-nCoV Pneumonia: Relationship to Negative RT-PCR Testing
Some patients with positive chest CT findings may present with negative results of real time reverse-transcription–polymerase chain- reaction (RT-PCR) for 2019 novel coronavirus (2019-nCoV). In this report, we present chest CT findings from five patients

A brief history of RT-PCR and our laboratory experience with SARS-CoV-2 analyses using RT-PCR
Polymerase Chain Reaction (PCR) is in vitro replication that allows accelerated amplification of certain sequences in small DNA fragments. A sensitive technique, only traces of DNA are needed for PCR to produce enough copies to be analyzed.

Positive RT-PCR Test Results in Patients Recovered From COVID-19.
This case series describes reverse transcriptase–polymerase chain reaction (RT-PCR) test results in 4 health professionals discharged from hospitalization or quarantine after 2 negative RT-PCR test results and resolution of clinical COVID-19 infection.

In situ polymerase chain reaction (PCR) is a histological technique that exploits the advantages of PCR for detection of mRNA directly in tissue sections. It somehow conjugates together PCR and in situ hybridization that is more traditionally employed for mRNA localization in cell organelles, intact cells, or tissue sections. This chapter describes the
