Quidel Shares Plunge on Warning

A surprisingly light flu season is drawing to a close, which is good news except perhaps at San Diego-based Quidel (NASDAQ: [[ticker:QDEL]]), which makes rapid diagnostic tests. Investors hammered the stock after Quidel said it anticipates a first quarter loss due to a significant decline in sales of its diagnostic products for influenza and Strep A. Quidel shares lost $1.91, or 19.4 percent, to close at $7.92 a share. Quidel CEO Douglas Bryant said in a statement today, “the number of doctor visits for influenza-like illness is significantly lower than the prior year.”
