PCR tests look for genetic matter from the new coronavirus using amplification cycles. However, the number of amplification cycles that was needed to detect genetic matter from the virus, which is referred to as the cycle threshold, typically isn’t included in test results sent to doctors and patients. Many coronavirus tests have fairly high cycle thresholds, with most set at 40 and some set at 37. That means a number of patients who aren’t carrying much of the new coronavirus are still testing positive, even though they may not be contagious.
