A PCR test is a viral test that tells you if you have a current infection. Two types of viral tests can be used: nucleic acid amplification tests (NAATs) and antigen tests. NAATs detect genetic material (nucleic acids). NAATs for SARS-CoV-2 specifically identify the RNA (ribonucleic acid) sequences that comprise the genetic material of the virus. (source: CDC) In some cases a sample may be sent to an outside laboratory for processing. Results for these tests take around 2-3 business days (weekends and holidays may delay processing). PCR Tests are considered the gold standard and rely on DNA amplification to produce consistent, reliable results. Results are usually ready in 2-3 days.
