Why Choose PCR Over Antigen Testing

In the past, diagnoses were limited to what could be observed by an attending physician with their own senses. As one might expect, this resulted in wildly varying levels of patient care and unconventional tests and treatments, many of which unfortunately involved livestock. Fortunately, the modern era has seen vast advancements in the area of molecular biology, and by extension, medical diagnosis. Today we have definitive tests for many conditions and diseases ranging from infertility to cancer. Recently, the world has seen a dire need for a rapid means of determining if a subject is positive

  1. Why Choose PCR Over Antigen Testing? Theoretically, only one copy of the DNA being studied is required for detection, as it is amplified millions of times. Antigen testing requires thousands of virions to be present in the sample to have a positive result.1 This is detrimental for early detection, especially in asymptomatic cases as oftentimes the viral load in the sample will be too low to properly register, leading to a false negative. Conversely, false-positive tests are also more likely with antigen-based tests.4 This is due to the fact that related viral species may bind in the place of the SARS-CoV-2 virus, thereby eliciting the colour or fluorescence change.4 A false positive test result can be a traumatic experience, possibly resulting in financial, psychological and even physical harm.4 Every possible effort should be made to ensure that all positive test results are accurate to avoid unnecessary anguish. Parting Thoughts Current Ontario policy states that any positive rapid antigen test should be confirmed through a subsequent PCR test. Though it may take a little longer to get your results, the increased security of the higher sensitivity provides peace of mind not given with the antigen test. Puretesting's PCR test provides affordable, quick, and accurate COVID-19 testing for both businesses and individuals. It merely requires the individual to spit into a tube, add the provided preservative and ship it to Puretesting for processing and analysis by our experienced scientists. Within 24 to 48 hours, you will have your result, and with it, your peace of mind.
