With the rise of COVID-19, the detection of viruses has become an important matter. Of the various methods of COVID-19 detection, the two methods that received the most press are Real-Time PCR Testing and Rapid or Antigen Testing. 

Real-Time PCR Testing

What Does PCR Mean?

PCR is an abbreviation of Polymerase Chain Reaction. The test detects genetic material from a specific organism, i.e. a Virus. This test can detect whether you got infected at the time of the test. Mainly, it gives accurate results to the extent if you have been exposed to COVID-19.

How is PCR Testing helpful In Detecting COVID-19?

PCR is a molecular test that uses upper respiratory specimens to detect any external RNA. Lab scientists use PCR technology to amplify small amounts of RNA obtained from respiratory or saliva samples. SARS-CoV-2 is the virus causing COVID. 

The RNA is amplified to such an extent until its presence is detectable. PCR testing is relied on universally for its reliability and accuracy.

Rapid (Antigen) Testing

Antigen tests are used for a quick peek at whether an individual has been exposed to COVID-19 using a remote test kit that can be purchased at a drug store or online. These Rapid test kits are far less reliable than RT-PCR. Test data on antigen tests show up to 50% accuracy within the first 5 days of exposure. This means a high rate of false-negative results. 


The PCR test gives more accuracy when testing for COVID. The collected specimen is amplified to such an extent that if there is any fragment is present though. 

Same Day PCR COVID Testing

Same-day PCR COVID testing is gaining more acceptance as compared to the prior method of testing that takes 4-5 days for the result. The reason behind Same Day Testing is that it gives immediate and instant results and gives more accuracy. 

The Same day PCR test uses the most advanced testing machines that target abundant protein present in the virus. Thus, the same-day PCR testing method directly assesses the presence of viral protein, therefore it is different from molecular tests.

The Same day PCR testing is more advantageous than any other COVID test, with a quick turnaround time. This test is relatively inexpensive and easy to interpret. It gives more accurate results and is comfortable for serial testing.
