Antibody tests are the key to open the economy. The Muslim Times has the best collection for the war against Covid 19

Swiss drugmaker Roche said on Sunday it expects to be able to produce “significantly more” than 100 million of its new antibody tests monthly by the end of 2020, doubling its current production.
Roche earlier on Sunday received an emergency use authorization from the U.S. Food and Drug Administration approving its test, which relies on taking intravenous blood samples to identify whether someone has previously been infected with the coronavirus and whether they have the antibodies to defend against it.
Roche said its Elecsys Anti-SARS-CoV-2 antibody test has a specificity greater than 99.8%, meaning very few false-positive tests, and that it can help assess people’s immune response to the virus. The company said it has already started shipping the new antibody test to top laboratories globally.

(Reuters) – Roche has won emergency approval from the U.S. Food and Drug Administration (FDA) for an antibody test to determine whether people have ever been infected with the coronavirus, the Swiss drugmaker on Sunday.
Thomas Schinecker, Roche’s head of diagnostics, said the company aims to more than double production of tests from about 50 million a month to significantly more than 100 million a month by the end of the year.
Governments, businesses and individuals are seeking such blood tests to learn who may have had the disease, who may have some immunity and to potentially craft strategies to help end national lockdowns.
Basel-based Roche, which also makes molecular tests to identify active COVID-19 infections, said its antibody test has a specificity rate exceeding 99.8% and sensitivity of 100%, meaning tests would show very few false positives and no false negatives.
A false-positive result could lead to the mistaken conclusion that someone has immunity. Roche said its test relies on intravenous blood draws, with higher accuracy than finger-prick tests.
“If you take blood from a finger prick, you will never be able to achieve the same level of specificity that you will achieve … when you take blood from the vein,” Schinecker said.
“You have to have very, very high specificity. Even 0.1% or 0.2% makes a difference.”
RIVALS’ TESTS
Similar antibody tests have also been developed by companies including U.S.-based Abbott Laboratories, Becton Dickinson and Italy’s DiaSorin.
Abbott has said the specificity and sensitivity of its test are 99.5% and 100% respectively. Diasorin has said its Liason XL test has 97.4% sensitivity and 98.5% specificity.
