PCR Test Saliva

PCR Test Saliva

PCR Test Saliva detects if there is a COVID-19 infection with a simple saliva sample with the mosts confidentiality and highest level of reliability.

This test is intended for the qualitative detection of SARS-CoV-2 nucleic acid in saliva sample and allows to know if the patient is infected by coronavirus with the same reliability as with the usual nasopharyngeal exudate (99%).

A positive result confirms the detection of the virus. A negative result does not always mean absence of the virus as it depends on the viral load of the sample. If a negative result is obtained from a patient with a high suspicion of SARS-CoV-2 virus infection, it should be confirmed with a new test.
