Spanish capital ditches ‘unreliable’ Chinese coronavirus test kits

[jericho]

I believe the Chinese reached their threshold for lockdowns and its economic consequences.

Its hard to tell if they are telling the truth or not, but for the sake of everyone, I hope it is true. I can't imagine how it would be if this virus is left unchecked.

Chinese government only control heath are in China not Spain or Czech Republic, we can't stop you from buying things. Lol

Sorry, you are WRONG.

If something is NOT approved to be used as a medical test, you cannot market it as "diagnostic test" like this piece of shit Chinese company is doing.

Ppl like you buy it online. They are not approved to be sold in China. China government don't control the health care in other countries.

No dear, it is a GOVERNMENT agency who bought it in case of spain.

According to gay.com, anal sex is good for hemareoids too.

@jaibi Yo Mod! Lets see how much "modding" you do when its a Chinese in question.

Its the ancient Chinese custom of "saving the face". Even seen Xi-Ding-Dong "taking responsibility" for any thing wrong? Usually it is pushed down upon a low-level fall guy, bureaucrat or something similar. No wonder they have such a culture of "closed information" and "secrecy". Why do you think they kicked out all the foreign journalists?

not to worry the Chinese have claimed victory over COVID, consider COVID vanquished, slain, kaput, banished never to return. Even if it goes on to kill many more people in China, no one will ever know.

Now China has a list of "classified " suppliers and somehow Spain is at fault for not knowing about which "classified" suppliers sell good test kits and which one sell juju,because, in communist China, apparently, companies can export anything in times of crisis without any supervision. Looks like the commies are peddling propaganda again, they're throwing one of their companies under the bus.
Yesterday, the Czechs were to dumb to read their awe inspiring test kits, today the Spaniards are idiots for not buying from official "clasified " companies.
The virus came from Mars btw,trust Xijinping and the marxist utopia which shut down the internet, arrested it's own doctors and deported foreign reporters when the epidemic started.

Except the company advertises its products as something to diagnose disease in humans.
If you are not approved you cann't do that, unless you are Chinese of-course.

"However, according to seznamzpravy.cz, doctors and hygienists were informed that this might happen. Indeed, the rapid tests that arrived from China a few days ago do not reliably detect the infection at an early stage.
According to a document of the National Institute of Public Health, rapid tests have only a “supporting role” in testing.

The institute explained that these tests cannot detect the virus in the first five to seven days after being infected as the person has yet to start producing coronavirus antibodies in the blood. The rapid tests are based on detecting these antibodies, though.

“The test is not a diagnostic test,” the National Institute of Public Health stated.

In other words, it is better to use these tests at the end of the 14- days quarantine period to confirm if the person suspected of having coronavirus is indeed infected.

Hygienists in Ostrava have already announced that they will introduce such a system, using the tests on people who were placed under preventive quarantine but not tested."

As suggested by the manufacturer, RTK are only for supporting and emergency use, not a standard way to diagnose patients. When you have too many patients but not much time, they can at least help you catch some infected. Many testing systems have to work together to find as many infected patients as they can.

How do you explain a test which was supposed to have a 80% accuracy to only give 30% accuracy in reality?
Unless you are Chinese, then we have to allow for "Chinese Quality."

The law works differently in China fentayl is banned in US not China, they can produce and sell it. Certain medical products are not authorized for use in China, we can export it too. Its up to Spain or Czech to test and approve it. My question is they must be damn desperate to use unapproved products right? And BTW when I SAY you guys, its meant to be a general statement. Don't take it personally.

Then why does Chinese manufacturer market it as one?

Rest of the world marks such "tests" as "Research Use Only".

It depends on how you use it. You can sell a monkey pens but if he uses it ro scratch his butt,... Lol

This kinds of rapid testing kits from various countries work the same way

‘10-minute diagnostic tests not recommended due to inaccuracy’

As the world is grappling with the new coronavirus pandemic, many have called for the introduction of rapid diagnostic tests (RDTs), which can produce results in around 10 minutes.

Healthcare experts, however, did not recommend using them due to inaccuracy, at a YouTube show Tuesday by K-Healthlog, a channel operated by The Korea Doctors’ Weekly.

RDT results come out quickly, compared to real-time polymerase chain reaction (PCR) tests now used in Korea, which take about six hours to screen out COVID-19 patients. However, RDTs have 50 to 70 percent of sensitivity, compared to PCR tests, meaning that a COVID-19 patient could test false-negative, or a healthy person could test false-positive. Such inaccuracy will add confusion, experts said.

Diagnostic testing for viral infections includes molecular diagnosis, cell culture, and antigen/antibody testing. RDTs use antigens or antibodies. Usually, it takes about two to four weeks for a human body to develop an antibody against infectious disease, antigen detection is used more for RDTs than antibody detection.

Lee Hyuk-min, director of infection control affairs at the Korean Society for Laboratory Medicine, said it was too early to introduce RDTs during a YouTube live show, K-Healthlog, hosted by The Korean Doctors’ Weekly, on Tuesday.

“Antibody testing can check the viral infection by targeting an antibody that develops after a virus gets into a human body. But the entry of a virus does not create an antibody right away,” Lee said. “So, we use antibody testing in the late-stage viral infection to look at epidemiologic linkage rather than in the early-stage infection.”

Antigen testing, often used in RDTs, is also inaccurate, compared to molecular diagnostics, he noted.

“Antigen testing amplifies a signal using various methods. So, their sensitivity is lower than the PCR tests. In clinical settings, the sensitivity of antigen testing for influenza infection is 50-70 percent of that of PCR tests,” Lee explained.

Antigen testing requires several conditions, and the most important condition would be persuading the public to tolerate inaccuracy of the test, Lee went on to say.

“If a diagnosis of flu goes wrong, a patient might get angry, but it won’t be a serious problem. But if COVID-19 testing gets wrong, it will be more than that,” Lee said.

On the condition that a treatment is available and quick diagnosis is necessary, antigen testing could help, he said. However, the nation has to mitigate the spread of COVID-19 as much as possible, so physicians are doing PCR tests, not antigen testing, he added.

Shin Hyun-young, a professor of family medicine at Myongji Hospital, said flu offers many other options for physicians because doctors could still prescribe Tamiflu at their discretion despite a wrong diagnosis.

‘Korea capable of 20,000 daily PCR tests, no need for RDTs’

In a joint statement, six diagnostics societies in Korea said, “It is very dangerous to introduce rapid diagnostic tests to detect COVID-19 during this global pandemic.”

RDTs using antigen or antibody can quickly yield results within about 10 minutes. Still, their accuracy is significantly low at 50-70 percent of that of molecular genetic tests, they said.

“Due to false results, an infected patient could freely move around without a diagnosis and transmit the virus to others, or a healthy person could be hospitalized for no reason, waste medical supplies, and become vulnerable to unnecessary infection risks, causing grave social confusion,” they said.

Korea has already established a system for massive molecular genetic tests, capable of conducting 15,000 to 25,000 PCR tests, and the accurate testing needs only about six hours, the statement said. “At this moment, Korea does not need to introduce RDTs.”

I don't know any place in the world where lying "30 is 80" is allowed by law. May be a Chinese thing.

What the hell Chinese language got to do with anything?

Anybody can lie online and on their products, we can't stop them selling to you. We can stop them from selling only in China. BTW its accuracy depends on when you use it and how you use it.

We mark things in Chinese. Can you read it genius?
