Tm Bioscience Corporation Cystic Fibrosis Test Now Has CE Mark

TORONTO, Jan. 11 /PRNewswire-FirstCall/ - Tm Bioscience Corporation , a leader in the commercial genetic testing market, today announced that its Tag-It(TM) Cystic Fibrosis (CF) Kit now has the CE Mark (“Conformite Europeene”), allowing the genetic test to be marketed for diagnostic purposes in the European Union and other countries that recognize the CE Mark.

“Having the CE Mark on our Tag-It(TM) CF test expands our reach into the European market for CF testing and further asserts our leadership position in the clinical genetic testing market,” said Greg Hines, President and CEO of Tm Bioscience.

“A proven, highly accurate and affordable cystic fibrosis molecular test is needed for the European market for carrier screening and as a tool for diagnosis of newborns,” said Dr. Jeremy Bridge-Cook, Vice-President, Marketing and Business Development. “The Tag-It(TM) CF Assay has a demonstrated track record of meeting this need in the North American market and we look forward to providing European customers these same capabilities.”

The Tag-It(TM) Cystic Fibrosis Kit is used to simultaneously detect and identify mutations and variants in the cystic fibrosis transmembrane conductance regulator (CFTR) gene in human blood or blood spot specimens in order to determine CF carrier status in adults, as an aid in newborn screening, and in confirmatory diagnostic testing in newborns and children. Performance testing has established that the Tag-It(TM) CF Kit operates with 100% accuracy and greater than 99.9% reproducibility and precision.

The Tag-It(TM) Cystic Fibrosis (CF) Kit is also the first multiplexed human disease genotyping test to be cleared by the U.S. Food and Drug Administration (FDA) as an in vitro device (IVD) for diagnostic use in the United States.

Cystic Fibrosis (CF) is the most common autosomal recessive disorder in the Caucasian population, with an incidence of approximately 1 in 3,200 live births. The Tag-It(TM) Cystic Fibrosis Kit simultaneously screens for 39 cystic fibrosis transmembrane conductance regulator (CFTR) gene mutations and 4 variants (polymorphisms) prevalent worldwide.
