PCR Test Vs. Rapid Antigen Test, what are the difference?

Since the pandemic, people have been given strict safety measures to prevent further transmission of the virus. It includes wearing masks, following proper hand hygiene, social distancing, and quarantine protocols.

However, many are left unprepared for the virus’s fast spread. As such, various states and countries have begun to be more vigilant and started requiring COVID-19 testing for individuals, especially workers and travelers.

For people seeking to travel, many airlines now require people to present a fit-to-fly certificate as proof that they do not have an active coronavirus infection and, therefore, are allowed to travel. Like people in the UK, travelers should undertake the Fit to fly covid test.

If the fit to fly covid test in Birmingham resulted negative, only then shall they receive a certificate. For more accurate results, taking a PCR Test is more advisable.

Two types of diagnostic tests are primary used for identifying a person with an active infection: the polymerase chain reaction or PCR test and the Rapid antigen test. While many are aware of both tests being used for COVID-19 testing, not everyone knows its differences.

A PCR test is performed to detect the genetic material of an organism, such as a virus. It can detect whether or not a person is currently infected or has been in the past to detect fragments of the virus. Results are available in less than 24 hours: however, its turnaround time can take days.

On the other hand, Rapid antigen tests are used in screening many people as they can produce results in less than 30 minutes. They are also easier and cheaper to produce. However, the chances of missing an active infection are high. Nevertheless, many prefer this test as they fast and low cost.
