NEW YORK (GenomeWeb News) – CombiMatrix today announced a 27 percent rise in first-quarter revenues, driven by a 158 percent jump in sales generated by its prenatal chromosomal microarray analysis testing services.

The Irvine, Calif.-based molecular diagnostics company said that total revenues for the three months ended March 31 increased to $1.6 million from $1.2 million in the first quarter of 2012. Growth in prenatal testing revenues was driven by a 124 percent increase in billable test volumes, as the firm noted when it released its preliminary results one month ago.
