As Zika fear spreads, FDA gives Roche test emergency authorization

With concerns over a continued Zika outbreak growing, the Food and Drug Administration has given Roche Holdings emergency approval to use one of its Zika blood testing kits.

The approval, which lasts as long as the emergency is ongoing, will allow for testing of the virus through Roche's LightMix Zika rRT-PCR test, which has not been approved by the FDA yet.
