In addition to RT-PCR testing, some experts argue that CT scans can diagnose COVID-19. Others disagree. Medical News Today spoke to two doctors who present their opposing viewpoints.
As the COVID-19 pandemic continues to claim lives across the globe, early diagnosis of people with SARS-CoV-2 is essential. Once a person has received a diagnosis, limiting their physical contact with others is one way to slow the spread.

For many, the use of reverse transcriptase polymerase chain reaction (RT-PCR) is the gold standard. This molecular biology technique detects genetic material that is specific for the SARS-CoV-2 virus. Yet, RT-PCR is not 100% accurate, and some experts have raised questions around false-positive and false-negative test results.
