Abbott Labs on Thursday said it was awarded a contract to supply millions of its laboratory-based IgG antibody tests to National Health Service laboratories in the U.K.

Abbott said it has already shipped 800,000 antibody tests to NHS laboratories, which will be used as part of a testing initiative announced Thursday by the U.K. Secretary of State for Health.

The company said the antibody test will use its ARCHITECT i1000SR and i2000SR and Alinity i laboratory instruments, and added, "As one of the most widely used laboratory systems in the world, the ARCHITECT system can run up to 100-200 tests per hour to help hospitals and laboratories with reliable antibody testing during the pandemic."
