In the months since the COVID-19 panic began health authorities around the world have told the public to “get tested” to help track the spread of SARS-CoV-2. However, as fear and hysteria subside, the scientific community and public at large are calling into question the efficacy of the test used to determine a patients status...The most common test is a polymerase chain reaction (PCR) lab test. This incredibly sensitive technique was developed by Berkeley scientist Kary Mullis, for which he was awarded the Nobel Prize in 1993. The test is designed to detect the presence of a virus by amplifying the virus’ genetic material so it can be detected by scientists. The test is viewed as the gold standard, however, it is not without problems.
The PCR test uses chemicals to amplify the virus’s genetic material and then each sample goes through a number of cycles until a virus is recovered. This “cycle threshold” has become a key component in the debate around the efficacy of the PCR test.
Dr. Persse says that when the labs report numbers of COVID-19 cases to the City of Houston they only offer a binary option of “yes” for positive or “no” for negative. “But, in reality, it comes in what is called cycle-thresholds. It’s an inverse relationship, so the higher the number the less virus there was in the initial sample,” Persse explained. “Some labs will report out to 40 cycle-thresholds, and if they get a positive at 40 – which means there is a tiny, tiny, tiny amount of virus there – that gets reported to us as positive and we don’t know any different.”
Persse noted that the key question is, at what value is someone considered still infectious?...

A question I have of Freepers in the know--that is Freepers who may be medical lab technologists or the like: When it comes to PCR tests for other virures, how many "cycle-thresholds" do you test out to?
i he the authpr was asking rhetorically
never been about the virus
its been about control
I think he is asking both rhetorically and as a matter of logic.
I would like to know this as well.
The “gold standard” CDC has totally screwed up the COVID-19 testing. Both from efficacy and timing.
They are still flatfooted, and as also the statistics center for the US gov’t, totally partisan and lame. Defund the CDC before defunding the PoPo.
My suspicion is that the elites and global multinationals want the genetic profile of everyone in the world. What will they do with the information? Nobody knows.
I recall a phrase from Nazi Germany that went “Life unworthy of life.” That is what the desire to know or they want to know who to harvest blood and organs from to prolong their lives and further research.
What I would also like to know is why we aren’t experimenting to see how infected a person has to be to infect others to the point that they get sick.
I mean, we have all these college students paying 20K or more to hole up in their dorms and take online classes.
Why not send one of these marginally-infected people to spend the weekend with them and see if they get infected to the point they get sick because at their age they won’t likely get dangerously sick? Their tuition for the semester can be discounted 5K for volunteering for the experiment and more than that if they actually get sick.
Do you have the Wuhan Flu?
1: That depends on how may cases we need in order to lock you down. If we need more then go to step 2
2: You will when we get done (testing).
If it looks like duck crap, smells like duck crap and you saw it come out of a duck’s butt, then it’s duck crap.
Except when a Democrat governor says it’s not.
Well the answer is obvious. They want the test that will ultimately produce the most positive results as possible. Beyond 25 replication processes is where you start to get the smallest trace amounts to garner a positive test result.

Will you let it run you life?
I have a mask that says “Covid 1984.”
Today two clerks told me that they liked my mask. Then they asked me what it meant.
They walk among us. Idiots.
OUTSTANDING!
I’ll look for one.
Not so strange we have a couple Doctors posting here that buy it too.
PCR is usually used as a confirmatory test, i.e. there is a (+) ELISA test or some other lab test that is used as a screening device.
This whole thing is really about Bayseian statistics which is the general approach we use in medicine. Using a complex set of statistics you can measure the accuracy of the test (Sensitivity and specificity) and the accuracy of diagnosis (positive predictive value and negative predictive value).
With PCR, you can augment enough that you get a set of genes that look like the disease, in this case, CoVID. But the question is, does this positive result bear the disease state. As you now know, this test can augment such a tiny bit of genetic information that you can either have a late false positive (inert virus that takes 90 days to clear from the LRT) OR a high amount of amplified virus in the whole.
Thus, the positive predictive value of the test is pretty high (if it Is positive, you can certainly bet you have a portion of the virus in the sample). BUT, what to do with a (+) — it may be (+) but there may NOT be the disease state or transmissibility. So, its a conundrum
The reason that PCR was selected for this was an ELISA type test would have taken longer to create I suspect, and there was a lot of of pressure brought to bear early on to get a test. So PCR was selected knowing is imperfections. The virus was well known in terms of its complete mapping (pretty easy to map a virus apparently) so, get a sample, PCR it and see if it is there.
This has lead to the problems of having a highly specific test that would usually be required to confirm a disease without the other leg which is a sensitive test which would tend to rule out the disease
This should be as clear as mud...
There is a real art to diagnosis, knowing your tests and properly then making a call. I have a zillion patients who are testing positive at day 60 and 90 but are obviously fine. What to do with this information?
One thing for sure, this test is probably over diagnosing the actual disease state, which is being politicized and used to exert tyrannical control over the populace. It is an abuse of science for sure.
In my study of communist societies, I came to the conclusion that the purpose of communist propaganda was not to persuade or convince, not to inform, but to humiliate; and therefore, the less it corresponded to reality the better. When people are forced to remain silent when they are being told the most obvious lies, or even worse when they are forced to repeat the lies themselves, they lose once and for all their sense of probity. To assent to obvious lies is in some small way to become evil oneself. One’s standing to resist anything is thus eroded, and even destroyed. A society of emasculated liars is easy to control. I think if you examine political correctness, it has the same effect and is intended to.— Theodore Dalrymple
Love your homepage quote. I’ve really liked Dalrymple, yet hadn’t seen that one. Cool ‘Cat
Modern society is hypnotized by socialism. It is prevented by socialism from seeing the mortal danger it is in. And one of the greatest dangers of all is that you have lost all sense of danger, you cannot even see where it’s coming from as it moves swiftly towards you. - Aleksandr Solzhenitsyn
Violence does not and cannot flourish by itself; it is inevitably intertwined with lying. - Aleksandr Solzhenitsyn
The site I bought it from does not appear to sell it anymore.
This site sells them, but they cost much more than I paid. However, some of the designs are better.

But I see now that the site I just gave you also sells BLM and Antifa stuff.
The site I used didn’t. And the masks were made in the U.S.
TeeSpring has them. I don’t think they sell Antifa or BLM stuff.

Yep...so that the idiot Governors can go by NUMBER of INFECTED (which is likely ALMOST everyone), instead of NUMBER of HOSPITALIZED.
Our 15 Days to Flatten the (Hospital) Curver is now nearing Day 170.
Totally absurd.
