Item 7.01
Regulation FD Disclosure

On March 26, 2010, Laboratory Corporation of America® Holdings (LabCorp®) (NYSE: LH) announced that it is the first national laboratory to offer customers a 21-marker genetic analysis in combination with a double-blind process for parentage/relationship testing on every sample. The testing utilizes two kits developed for LabCorp by Promega Corporation of Madison, Wisconsin.  The kits consist of 20 autosomal genetic markers and one gender marker.  The kits have overlapping genetic systems that, when coupled with independent DNA extractions, yield a double blind test for every sample. 
 
The main purpose of parentage/relationship testing is to detect if the proposed relationship is incorrect.  This newest innovation greatly increases the ability to make this determination. For paternity testing, the number of genetic markers (known as “loci”) used by laboratories to exclude a man in a typical case has increased over the years, giving a more definitive result of non-paternity.  With the new test panel of 21 markers, over half of the non-excluded men have combined paternity indices of greater than one billion to one and more than 95% had combined paternity indices greater than one million to one.  When a man is not excluded, the typical paternity test will have a probability of paternity of 99.9999%.
