..for Antibodies ????  and negative in a RT-PCR C19 Test. 

 

I disembark to Thailand in 3 weeks and I would like to ask, generally speaking - do having AB increase the risk for also showing up as a 'false positive' in a PCR Test? It's my understanding the opposite (meaning, my 'body' is in full flex fighting against this virus). 

At no time you had symptoms?

Last time I was sick was the first week of february last year (almost exact 1 year ago). Got the worst flu I've ever encountered. 

I did the antibodies-test last week so I don't know when/where I got the infection, or if it was the above mentioned flu.

Interesting, probably last Feb, assuming you were in Thailand, if not probably an asymptomatic dose

No, antibodies should not increase the risk of having a false positive RT-PCR test. The antibodies will most likely help prevent you from being re-infected ( unknown how well).

 

The RT-PCR will use a reverse transcriptase enzyme to make a complimentary DNA strand. Then they use Polymerase chain reaction to multiply the DNA. Something called a primer will only bind (and then allow replication of the DNA) if the DNA matches close enough to the complimentary DNA sequence from COVID RNA. 

 

Your antibodies are proteins that can attach itself to the virus (such as on the spike protein). 

 

The 2 tests are quite different. False negatives are more likely than false positives, but all dependant on the quality of the test and human-error.

 

Good luck with your travels.

Interesting! Thanks a lot. ????

10 years ago I had a STD test when I went back home from Thailand. The test was negative, but antibodies were detected in my blood. The Dr told me that I need to check for HIV ????????. "Shingles" (VZ virus) caused antibody in my system for years. Even 3 years ago it showed itself by very mild skin infection for 3 weeks and gone again. 

Detecting antibodies does not mean detecting COVID.

Did you get tested for Covid in Feb, or are you just self diagnosing yourself as having had flu.

 

A post making multiple unsubstantiated/unsourced coronavirus claims has been removed. In addition, any graphics posted need to include a weblink to the original, credible source.

aldriglikvid wrote ‘I did the antibodies test last week’ which identified he has ‘had’ covid recently.

But, he just can’t be sure when he had Covid-19 but its possible the worst flu he’s ever encountered was actually Covid-19.

 

There are a number of people with claims they had a hideous flu early on last year or towards the end of 2019.

My wife and I experienced the absolute worst flu ever at the end of 2018, not 2019.  It came on fast with fever and made it hard to do much anything. My wife was diagnosed at the hospital with the H1N1-2009 flu. This is the 2009 pandemic flu that still rattles around the world including Thailand.

 

This H1N1 flu was also prevalent in Thailand in February 2020, see this link/graph.

 

The chances of getting a bad flu in February 2020 were much higher than getting covid-19. This may be what many experienced end 2019 to Feb 2020.

The antibody test does not mean anything, its just a trick to get your money. It can detect antibodies of other coronaviruses, just read the lab website.

Interesting! 
 

Yes, I was in Thailand when I got this "new level of flu", in early February of 2020. Those dates, if you recall, we didn't know terrible much about the virus or to the extent it had spread outside of China. 

And - by the way, I did a public (and free) RT-PCR Test the other day and it came back negative.
