Pcr Test Accuracy

While PCR may require more resources and time the benefit of having an accurate way of detecting COVID infection is instrumental for learning how and where the virus spreads. The fewer cycles required the greater the amount of virus or viral load in the sample.

Experts from the University of Birmingham claim they have developed a. According to a Johns Hopkins study this so-called gold standard RT-PCR test can have a false negative up to 20 to 66 percent of the time in even symptomatic patients depending upon the tests timing.

The Cleveland Clinic describes the tests as the most accurate and reliable test for diagnosing COVID-19. Even Wang Chen president of the Chinese Academy of Medical Sciences conceded in February that the PCR tests are only 30 to 50 per cent accurate. The greater the viral load the more likely the patient is to be contagious.

PCR tests are seen as being more accurate than lateral flow tests but in the past took longer to process and provide results. The PCR test provides a simple yes-no answer to the question of whether a patient has the virus. Individuals Performing COVID-19 Testing.
