Quidel says FDA approves test for Streptococcus bacterial infection

SAN DIEGO (AP) -- Quidel Corp. said Thursday that the Food and Drug Administration cleared a test that is designed to diagnose infections caused by Streptococcus A bacteria.

Quidel said the bacteria are the most common cause of bacterial throat infections and can cause rheumatic fever and other illnesses. The Streptococcus test will run on the company's Sofia testing system, which is designed to return a result within five minutes.

A Sofia test for influenza A and B was cleared in April 2012.

Shares of Quidel lost 52 cents, or 2.1 percent, to $24.43 in Thursday trading and were unchanged in aftermarket trading.
