[Understanding COVID-19 Test Results]

Summary Nucleic acid amplification assays, such as PCR, are technically sensitive tests, but false negatives are inevitable in clinical airway specimens Theoretically, there are no false positives, but in reality, false positives can occur due to human error Theoretically, there are no false-positives, but in reality, false-positives can occur due to human error When performing PCR testing for COVID-19, it is essential to estimate the pre-test probability and properly evaluate the post-test probability, assuming that false-negatives and false-positives are possible When performing PCR testing for COVID-19, it is essential to estimate the pre-test probability and to evaluate the post-test probability
