Siemens Healthineers AG said Tuesday that the U.S. Food and Drug Administration granted emergency use authorization for the SARS-CoV-2 IgG antibody test.

The German medical-equipment maker said the test, which also received the CE-mark and is broadly available globally, is the first antibody test authorized with a semi-quantitative detection claim to support clinicians in assessing the level of an individual's immune response to the coronavirus.

"Our high-quality antibody test helps clinicians assess the level of a person's immune response, which is an important tool to have at this stage of the pandemic," said Deepak Nath, president of laboratory diagnostics for Siemens Healthineers.
