Covid 19 PCR And Antigen Tests – Reasons For Different Results
SHARE

As you probably know by now, covid 19 tests are in greater demand these days compared to a while ago. There’s new data about the Omicron variant that can make picking and using various types of tests pretty confusing. 

The gold standard in Covid testing 

CBS News revealed that molecular tests for covid-19, like the “RT-PCR” technology used by many laboratories — known as PCR tests — are widely considered the “gold standard” for spotting the most infections caused by SARS-CoV-2.

The same online publication mentioned above noted that by comparison, “antigen” or “lateral flow” tests, which can be done at home and return faster results, are less sensitive than PCR tests.

On the other hand, it’s extremely important to note the fact that they could be useful for identifying cases when people are likely to be contagious.

“One review last year estimated rapid antigen tests might only detect on average 75% of cases that PCR tests can spot, with antigen tests performing best in symptomatic people within the first week of their disease.”

The same notes in the online publication mentioned above reveal the following: 

“Some public health officials have advocated for wider adoption of antigen testing by Americans — if they can manage to find one of the rapid at-home tests — as an added layer of protection that might spot more cases before they spread.”

The article also made sure to note the fact that most hospitals are still using PCR tests in order to identify covid 19 patients even though these are the most sensitive ones. 

Mind-blowing solutions to treat covid 19 

Earlier today, we revealed that there’s a very controversial issue that you might have been seeing all over the news lately – the interview that podcaster Joe Rogan held with the mRNA vaccine expert and inventor, Robert Malone.

Dr. Robert Malone went on the Joe Rogan Experience podcast to raise concerns over the covid 19 vaccines and also to touch a bunch of other interesting related issues. Check out our previous article in order to learn some juicy details about Famotidine – a potential covid treatment used by dr. Malone.
