Step-by-step explanation:
Documenting a pertinent negative on your PCR is important because it helps to fill up the narrative portion of the form, but more importantly, it shows that the absence of a specific symptom or finding is relevant to the assessment. In the context of a PCR test, a pertinent negative would mean that the test result is negative for the presence of a specific DNA sequence or a viral infection. For example, if a PCR test for a viral infection is negative, it suggests that the patient is not currently infected with that virus.
