Coronavirus pandemic: Hopes grow for antibody tests, but experts urge caution 0
The sun is only just rising in Berlin but Lothar Kopp, 65, is already standing in line outside a clinic in the district of Reinickendorf.
Along with a handful of mask-clad people standing two metres apart, he is here to give a blood sample — for antibody tests in the hope of finding out if he has previously contracted the coronavirus and since developed immunity.
“If I’ve already had corona then I’m not infectious,” said Kopp, hoping to test positive for antibodies as it could allow him to visit his elderly mother without the risk of spreading the disease.
As nations around the world look to ease curbs on public life, some experts have mooted the possibility of so-called “immunity passports” to allow those who have antibodies to return to work first.
In Germany, tens of thousands of tests have been performed and large studies are ongoing.
Elsewhere in the world, efforts are also under way to determine the so-called level of immunity in the population.
New York Governor Andrew Cuomo said last week that the state will be launching tests “in the most aggressive way in the nation” to find out how many have already had the disease.
In a rush to catch up with testing, the US regulator had even taken the extraordinary decision to allow commercial manufacturers to market their tests without formal authorisation.
But experts including from the World Health Organization have urged caution over the accuracy of the nascent tests.
Among the unknowns of the virus is how long immunity could last — meaning that even positive antibody tests may not be meaningful for long.
– ‘Nonsense’ –
Urging prudence, a WHO spokeswoman noted that there is “much discussion” over the antibody tests.
But “once we have validated tests we may still not know how well a positive result correlates with protection against disease or for how long the protection will last,” she told AFP.
Matthias Orth, a board member of the Professional Association of German Laboratory Doctors (BDL), said inaccuracies are a big problem.
People can test negative even if they have had COVID-19, he said.
“There are also quite banal coronaviruses that do not cause serious illness, and they can give a positive result.”
As for so-called rapid antibody tests — home kits that extract blood from your finger and promise a result within 15 minutes — Orth’s verdict: “They’re nonsense.”
More accurate tests will come within weeks, he said, but he stressed that “it’s a little too early to give patients a clear statement that they are definitely immune”.
– 70,000 tests –
Nevertheless, the studies, including one that started in Munich over the weekend with scientists picking 3,000 households at random to test for antibodies, are being closely watched.
A separate study is ongoing in Gangelt, in the Heinsberg district — where Germany’s first major cluster of infections was uncovered. So far, researchers have determined that 14 percent of the population had previously been infected.
Beyond studies, several pharmaceutical companies in Germany have also begun marketing such antibody tests — which must be analysed in a laboratory.
And around 70,000 tests have so far been processed by 54 laboratories, according to the ALM association of accredited medical laboratories.
Doctor Ulrike Leimer-Lipke of the Reinickendorf clinic, which has been offering antibody tests since mid-March, said: “I think it makes a lot of sense, because this way we can find out if people have immunity.
“It is very important for people if they have a grandmother or a mother or father who they care for, to know if they are already immune.”

Disinfectant COVID-19 Statement: Hillary Clinton tells Americans ‘Please don’t poison yourself because Trump thinks it could be a good idea’ 0
Former US Secretary of State and First Lady Hillary Clinton has blasted President Donald Trump after he suggested scientists should investigate inserting disinfectants into the body as a way to cure COVID-19 caused by the novel coronavirus.
Clinton, Trump’s 2016 bitter presidential rival, warned on Friday that people not to poison themselves based on the president’s advice.
“Please don’t poison yourself because Donald Trump thinks it could be a good idea,” she wrote on Twitter.
Clinton’s comment comes as Trump faces criticism from medical professionals for his remarks. Doctors and health experts urged people not to drink or inject disinfectant.
Trump said at his daily media briefing on Thursday that medical experts should explore whether inserting light or disinfectant into the bodies of people infected with the novel coronavirus might cure the disease.
He also asked if there was a way to use disinfectants on the body “by injection inside or almost a cleaning.”
“Is there a way we can do something like that by injection, inside, or almost a cleaning?” he said. “It would be interesting to check that.”
“Maybe you can, maybe you can’t … I’m not a doctor. But I’m, like, a person that has a good you-know-what,” Trump said, pointing to his head.
Trump claims remarks were ‘sarcastic’
On Friday, Trump on Friday said he was being sarcastic when he suggested a day earlier that scientists should consider exposing the body to light, heat and disinfectants the coronavirus patients.
“I was asking a question sarcastically to reporters like you just to see what would happen,” Trump told reporters at the Oval Office in the White House.
“I was asking a sarcastic — and a very sarcastic question — to the reporters in the room about disinfectant on the inside,” he continued. “But it does kill it, and it would kill it on the hands and that would make things much better. That was done in the form of a sarcastic question to the reporters.”
When a reporter pointed out that the president had turned to experts next to the stage when he presented the idea on Thursday, Trump claimed he was asking those officials “whether or not sun and disinfectant on the hands … can help us.”
Trump’s explanation raised eyebrows among those who watched the Oval Office briefing.
“It didn’t seem like it was coming off as sarcastic when he was talking and turning to Dr. Birx on the side,” Fox News anchor Bret Baier said on air after Trump’s retraction.
We have a ‘quack medicine salesman’ on TV
“We seemed to have a quack medicine salesman on television. He’s talking about things like disinfectant in the lungs,” Schumer said.
“We need real focus in the White House on what needs to be done. Instead of talking about disinfectant the president should be talking about how he’s going to implement testing. Which every expert says is the quickest path to get us moving again,” he added.
Trump’s dangerous comments forced Lysol manufacturer Reckitt Benckiser to issue a statement that “under no circumstance” should its products be administered into the human body.
The company said in a statement on its website that “due to recent speculation and social media activity,” they had “been asked whether internal administration of disinfectants may be appropriate for investigation or use as a treatment for coronavirus.”
“As a global leader in health and hygiene products, we must be clear that under no circumstance should our disinfectant products be administered into the human body (through injection, ingestion or any other route). As with all products, our disinfectant and hygiene products should only be used as intended and in line with usage guidelines. Please read the label and safety information,” the company said on Friday.
