How Our PCR Tests Detect COVID-19

‍

The polymerase chain reaction (PCR) test is currently the gold standard method for detecting COVID-19 viruses. By amplifying tiny amounts of viral genetic material, PCR can identify the SARS-CoV-2 virus in your system even before symptoms emerge.

In the Lab

‍

Your nasal sample is pre-treated with chemical reagents to isolate any viral RNA present. This extracted RNA then undergoes polymerase chain reaction amplification. Using thermal cycling, the sample is heated and cooled to exponentially multiply target genetic sequences.

Through this rapid amplification, PCR can detect extremely small amounts of viral RNA in your sample. Even if you are infected without symptoms, the test is sensitive enough to identify the SARS-CoV-2 virus by amplifying its genetic sequence.

Accurate Results

‍

The PCR process takes place in special lab equipment using fluorescently-labeled probes to confirm the presence of viral RNA. If SARS-CoV-2 is present in your sample, the PCR test will accurately detect it by binding to the virus’ genetic sequence.

Within 24 hours, you will receive your COVID-19 test results. With PCR testing, you can have confidence you are receiving the most reliable results backed by proven science and technology.

Reliable Detection for All COVID Variants

‍

A key benefit of PCR’s molecular detection method is its ability to reliably identify every COVID-19 variant by targeting conserved genomic regions. As the virus mutates, PCR keeps pace.
