CINCINNATI (AP) ¿ Meridian Bioscience Inc. said Thursday its profit rose 16 percent in its fiscal fourth quarter due to strong sales of its rapid flu test, which is marketed as a potential detector of swine flu. Meridian said its profit grew to $8.9 million, or 22 cents per share, from $7.7 million, or 19 cents per share, a year earlier. Revenue rose 16 percent to $42.5 million from $36.5 million. According to a Thomson Reuters survey, analysts were expecting 21 cents per share and $38.7 million in revenue. The company reported strong sales of respiratory products, including its TRU FLU kit, which is approved to detect seasonal flu. It also said sales of its test for the respiratory syncytial virus were solid. RSV is the most common cause of lower respiratory tract illnesses in infants and young children. In mid-September, the Food and Drug Administration allowed Meridian to update the packaging of TRU FLU to indicate it is sensitive to two swine flu strains. TRU FLU's ability to detect the strains has not been proved.
