Trump administration requires insurers to provide free antibody tests

The Trump administration said late Saturday it will require health insurers to provide free antibody tests that could provide better insight into the scale of the U.S. coronavirus outbreak.

Health experts agree that widespread antibody testing, which can detect who has developed immunity against the virus, is essential for being able to ease social distancing measures and allow healthy people to return to work.

Congress previously required that all Americans, including people without health insurance, receive free diagnostic tests to determine whether they are sick with coronavirus. The administration said it had authority from recent emergency rescue packages to mandate private insurers also provide antibody testing without out-of-pocket costs.

“It is critical that Americans have peace of mind knowing that cost won’t be a barrier to testing during this national public health emergency,” said Seema Verma, head of the federal CMS.

However, the new guidance did not make clear whether the free antibody tests would be extended to uninsured Americans. CMS did not immediately respond to a request for clarification.

The antibody tests will help determine how many people were infected who experienced no or minimal symptoms. It’s still not known how much immunity a person gains from the novel disease after infection.

Senior Senate Republicans Lamar Alexander and Roy Blunt earlier this week called on the administration to declare antibody tests free for patients.

“Free tests will help contain the disease and give Americans confidence that it is safe to go back to work and back to school and restart the economy,” they wrote.
