Roche Eyes COVID-19 Antibody Test Launch in May

Roche joins a global race to sell tests that demonstrate people's immune systems have developed antibodies in response to the new coronavirus

Roche joins a global race to sell tests that demonstrate people's immune systems have developed antibodies in response to the new coronavirus

Health departments, labs, and hospitals across the country are rolling out antibody testing for COVID-19.

Several reports have emerged of organisations seeking to purchase antibody tests for their employees, or of individuals purchasing these tests online for personal use.

The study estimated that 2.49 per cent to 4.16 per cent of people in Santa Clara Country had been infected with COVID-19 by April 1. Some seem to have the antibodies built up for a lifetime of immunity after recovering from COVID-19. The UK government had earlier this month said that none of the 17.5 million antibody test kits it had ordered worked well enough to be used, British media reported.

There is another kind of test, an antibody test, which is a blood test created to tell whether people have already had the virus and are now immune.

The test will screen blood samples for antibodies that show whether an individual has been infected with the novel coronavirus, the Basel-based company said. They may also be eligible to serve as potential donors of convalescent plasma. This limits the test's effectiveness for diagnosing COVID-19 and is why it should not be used as the sole basis to diagnose COVID-19. IgG antibodies remain longer in the body, suggesting possible immunity.

Right now, however, these antibody tests are brand new and still in development.

"Clearly people have an immune response, they do produce antibodies, and we can measure those antibodies".

The government, supported by world-leading experts and regulators, is continuing to work hard to rapidly deliver a reliable and accurate back-to-work antibody testing kit, to counter the spread of the virus and enable people to return to work safely.

"This is the working assumption: If you test and find people that have developed these antibodies, then at least for a certain period of time they will have gained immunity", Schinecker told Reuters.

"You can not use the RT-PCR method across a large population", a member of a medical panel guiding the government on its response to the Covid-19 pandemic told The Telegraph, requesting anonymity because the member lacked authorisation to the speak to the media.

Detailing India's testing strategy, the Health Ministry said that Real-Time PCR (RT-PCR) test and Point-of-Care molecular diagnosis are recommended for confirming COVID-19 among individuals belonging to the following categories All symptomatic individuals who have undertaken global travel in the last 14 days; all symptomatic contacts of laboratory confirmed cases; all symptomatic healthcare workers; all patients with Severe Acute Respiratory Illness (fever and cough and/or shortness of breath); and, asymptomatic direct and high-risk contacts of a confirmed case should be tested once between day 5 and day 14 of coming in his/her contact. Test for which developers have provided a notification are listed on the FDA's COVID-19 Diagnostics FAQ page.

"We need to ensure that they are validated so that we know they are actually measuring what they say they attempt to measure".

Totally, three tests were authorized by the FDA and their use outweighs the risks.
