The current Covid-19 pandemic imposes a diagnostic strategy for the care of patients. The sensitivity for the Covid-19 PCR is 56 to 83%. A single negative test can rule out Covid-19 in the majority of situations. However, since the negative predictive value of the test is between 88 and 95%, it is essential to ensure the follow-up of these patients. For those with typical symptoms, a negative test should be interpreted with caution and a second test may be indicated.
