The rapid coronavirus test being used to diagnose people at the White House may miss up to half of all positive cases, a new study suggests.

Abbott Laboratories' ID NOW test was hailed for being able to detect a positive result in just five minutes and a negative result in 13 minuets.

But researchers from New York University found that the ID NOW test missed one-third of coronavirus samples stored in vials compared to another commonly used testing kit.

What's more, among samples that were taken using a dry nasal swab, the test from the Illinois-based company missed 48 percent of positive results.
