Why is pcr test taking so long – none:.How long do PCR Covid test results take?

 

It will likely cost you hundreds of dollars. The molecular-based tests, considered the gold standard for detecting COVID , are a reliable tool but can take days to process, particularly as cases of the virus surge and people queue up for testing.

Unlike less accurate antigen tests , which can be used at the point of care and deliver results within minutes, PCR tests typically require the use of lab equipment as well as technicians who are trained to process and interpret the results. Clinics with their own onsite labs can process results more quickly. COVID testing has spawned a veritable cottage industry, with medically minded entrepreneurs stepping up to meet increased demand — often charging top dollar to expedite PCR test results.

Such services are undeniably convenient for those who can afford them. Yet they also underscore the ongoing constraints in COVID testing , which experts say is unfair for people of more modest means, and reflects wide gaps in insurance coverage for what’s becoming a necessary tool for many people.

Clear19 Rapid Testing, founded in March in an effort to contain the virus before vaccines became available, offers the speedier molecular-based testing services for a premium. Clear19 uses a robotic lab that can process 90, specimens overnight, delivering test results to patients within 24 hours. That’s why we can guarantee overnight results,” said Sandy Walia, founder and director of Clear The company also offers same-day testing, which Walia called “the private jet of testing.

The price for a rush test result? Molecular tests are more sensitive than rapid antigen or lateral flow tests, meaning they detect the virus, including the Omicron variant , early and before an individual is contagious in some cases. They are gentle and non-invasive, meaning patients are no longer required to practically have their brains tickled with a long, thin nasal swab. Walia expects that current strict testing requirements for travel, which vary by country, will eventually loosen, and demand for overnight and faster results will recede.

But testing will remain crucial for preventing the global spread of new variants. But if this thing is still around for a little while, testing will be the only way to prevent global spread,” she said. Sameday Health, another testing outfit started during the pandemic, has also sought to expedite the turnaround time for COVID tests. Emad, who says the self-funded company is already profitable, thinks demand for PCR testing will hold steady as cases of the virus remain elevated. However, the article above was published in November of That is two months before the WHO disavowed the test.

This person who wrote the quotes above has a Ph. In three sets of testing data that include cycle thresholds, compiled by officials in Massachusetts, New York and Nevada, up to 90 percent of people testing positive carried barely any virus, a review by The Times found. Most tests set the limit at 40, a few at This means that you are positive for the coronavirus if the test process required up to 40 cycles, or 37, to detect the virus.

This is amazing, as the FDA would have had to have known that by allowing high numbers of cycles in the PCR test that enormous numbers of false positives were being generated. The C. All of this means that the fact the tests were useless was known for many months before the WHO disavowed the PCR tests. The way the test was run brings up another problem. Lidiya Angelova goes on to explain how the PCR test needed to be run.

Drosten and his coworkers used sequence from China to create the primers for the test. It has multiple flaws which were discussed before but one seems never got a spotlight — reproducibility.

How did they determine the PCR test should have been used in the first place if they were never able to use it to identify covid? Tests must be performed in sterile conditions as the sampling. In reality none of it is done: different reagents, real samples, since the mass of the testing unqualified personnel, no sterile environment during taking the sample and after it.

This means that the test was really entirely experimental and designed to be run from a lab environment rather than from the field. The result is unreliable. There is no evidence if those samples are positive or negative! The diagnostic procedure most widely used for this purpose is based on the polymerase chain reaction PCR. The PCR is a very powerful and versatile method that lends itself to numerous applications in molecular biology, and also in the laboratory diagnosis of viral infections.

However, exactly because it is so powerful, PCR is very difficult to get right even at the best of times; it will yield accurate results only in the hands of highly trained and disciplined personnel. The enormous scale on which the method has been deployed during the COVID pandemic has meant that it was entrusted to untrained and insufficiently supervised personnel; in such circumstances, the mass manufacture of false-positive results due to the cross-contamination of samples is a disaster waiting to happen see for example [37].

Another thing that the WHO did not declare or admit is what the inventor Dr. Kary Mullis himself stated that the PCR is not really meant for diagnosing a viral disease or any disease as it is only for identifying nucleotides, very small fragments of DNA or RNA, for replication and enlargement so then experts can identify what they need to identify.

So the question here is… what is the WHO trying to identify when there is no actual genetic sequence to be modelled in the first place? Mike Yeadon, along with others, has published a scientific paper.

Yeadon stated:. In addition, in his video testimony, Dr. Reiner Fuellmich, a high profile German-American lawyer who already filed a class action suit together with another expert Dr. Wolfgang Wodarg also stated:. Yeadon, in agreement with the professors of immunology Kamera from Germany, Kappel from the Netherlands, and Cahill from Ireland, as well as the microbiologist Dr.

Arve from Austria, all of whom testified before the German Corona Committee, explicitly points out that a positive test does not mean that an intact virus has been found. The authors explain that what the PCR test actually measures is — and I quote:. Towards the end of the video, it describes that the PCR test provides false positives, which means nearly all the people who were declared to have died of covid did not die of covid, as they did not have covid. They had a false positive from a test that was never designed to be used to test if a person had covid.

Hmmmm…so the test is meaningless. Yet we breathlessly observe the test numbers as reported by media outlets and websites like world o meter. This is a very popular website. I checked it many times.

However, I had no idea that the number of cases is unknown as it relies on a test that does not work. Furthermore, the number of covid deaths is also greatly exaggerated as I cover in the article How the Covid 19 Mortality Rate Was Irresponsibly Exaggerated.

There are a lot of very nice graphs on this website, like the one above. The directive does not allow the counting of co-morbidities. Applied on April 16, , this directive was conducive to an immediate sharp increase in the number of deaths attributed to Covid One can tell by reading the documentation, or the Covid Test Fact Sheet that is given to those that are tested. Therefore, it is also likely that you may be placed in isolation to avoid spreading the virus to others.

There is a very small chance that this test can give a positive result that is wrong a false positive result. Your healthcare provider will work with you to determine how best to care for you based on the test results along with medical history, and your symptoms. This is not true, as has been covered already. Is this test FDA-approved or cleared? The PCR test standard was used for the vaccinated and unvaccinated groups. However, this undermines all of the math in all of the tests discussed so far.

How do we know the use of PCR testing at cycles was known by authorities to be fraudulent? Because now that the vaccine program has been rolled out the vaccinated are only given PCR tests at a reasonable 28 cycles, while the unvaccinated continue to be subjected to the fraudulent cycle PCR testing. This of course deceptively insures that the unvaccinated continue to generate completely asymptomatic false positives, and can then be made to appear to be driving the spread of the illness.

Meanwhile the vaccinated are much less likely to test positive given their testing is now, indefensible by any scientific measure, conducted at the lower 28 cycle threshold when compared to the unvaccinated conducted at cycles. Yes, so that could explain any difference between the vaccinated and unvaccinated groups. So both this test, and all other tests, including the tests submitted by Pfizer and Moderna and others to obtain emergency use authorization are now invalid.

None of the math I went through makes any difference as the PCR tests were never legitimate. Covid is not the first time the PCR tests created a number of false positives.

The following occurred back in For months, nearly everyone involved thought the medical center had had a huge whooping cough outbreak, with extensive ramifications. Nearly 1, health care workers at the hospital in Lebanon, N. Herndon, were told they appeared to have the disease; and thousands were given antibiotics and a vaccine for protection.

Hospital beds were taken out of commission, including some in intensive care. Then, about eight months later, health care workers were dumbfounded to receive an e-mail message from the hospital administration informing them that the whole thing was a false alarm.

Not a single case of whooping cough was confirmed with the definitive test, growing the bacterium, Bordetella pertussis, in the laboratory. Instead, it appears the health care workers probably were afflicted with ordinary respiratory diseases like the common cold. Now, as they look back on the episode, epidemiologists and infectious disease specialists say the problem was that they placed too much faith in a quick and highly sensitive molecular test that led them astray.

At Dartmouth the decision was to use a test, P. It is a molecular test that, until recently, was confined to molecular biology laboratories.

Kathryn Edwards, an infectious disease specialist and professor of pediatrics at Vanderbilt University. We are trying to figure out how to use methods that have been the purview of bench scientists. So even though the PCR tests failed in the field rather than a controlled and sterile lab environment and created a faux mini pandemic, they were introduced and accepted to test covid, where they failed once again. Curiously I found another article linked to the above article in the New York Times which carried ridiculous and false information about the PCR tests and proposed an even less accurate test be used.

During this pandemic, that has meant relying heavily on PCR testing, an extremely accurate but time- and labor-intensive method that requires samples to be processed at laboratories. As we have established, the PCR test may be time and labor intensive, but it is not accurate, much less extremely accurate.

But as the virus continues its rampage across the country and tests remain in short supply in many regions, researchers and public health experts have grown increasingly vocal about revising this long-held credo. This is amazing. It means that many people had no idea the PCR tests were incredibly inaccurate.

Outside of rolling dice or tarrot cards, there is no test less accurate than a PCR test. Health System. It is a catastrophe. Again this is another microbiologist who has no idea PCR tests are not effective tests. There is really no excuse for this ignorance by a person who works in the field. And these tests are still relatively scarce nationwide.

Government officials have pledged to astronomically scale up the number of point-of-care tests by fall, increasing by millions the weekly tally of tests conducted. The entire covid pandemic was driven by the faulty PCR test, and that generated the majority of its results as false positives. However, this is all based upon the belief in a test that never worked. A better option, Dr. Mina said, might be antigen testing, which identifies pieces of protein. Two such tests, made by BD and Quidel, have received emergency authorization from the F.

According to Dr. Angelova this test does not work for covid. And It was not broadly adopted. Daily testing? This shows the insanity of pandemic thinking. Furthermore, all of these topics might be of interest, but none of this ever happened. Concerns over accuracy bogged down the approval process for simple, speedy tests. That should not be difficult. Butler-Wu said. Katherine J. Wu is a reporter covering science and health. She holds a Ph. Well, none of that did any good.

This article is filled with false assumptions and nowhere does this reporter use her domain expertise to check on these assumptions. In addition to all of these problems, the CDC has the following problems in rolling out the tests. The faulty coronavirus testing kits developed by the Centers for Disease Control and Prevention in the early weeks of the pandemic were not only contaminated but had a basic design flaw, according to an internal review by the agency. Health officials had already acknowledged that the test kits were contaminated, but the internal report, whose findings were published in PLOS ONE on Wednesday, also documented a design error that caused false positives.

Benjamin Pinsky, the director of clinical virology for Stanford Health Care. What is curious is that while this document was published in May , many months later, we are still using antibody tests. It only detects antibodies against the virus [2]. Simply amazing. But not surprising. This raises several serious questions. And the answer to that question is obvious. If the FDA did develop such a test, then—in terms of conventional vaccine theory—it would be easy to see how well the vaccine is working, or not working.

Because UW testing guidelines have de-emphasized up front co-testing for multiple respiratory viruses, there is relatively little internal data to support a generalized conclusion at this time other than that co-infection with other viruses can occur. With another cycle, we have four copies: more light. What is the turnaround time?
