The FTC challenged Laboratory Corporation of America’s $57.5 million acquisition of rival clinical laboratory testing company Westcliff Medical Laboratories, Inc., alleging that the transaction would lead to higher prices and lower quality in the Southern California market for the sale of clinical laboratory testing services to physician groups. The complaint also alleges that LabCorp’s acquisition of Westcliff would leave only two significant laboratories in Southern California competing to provide critical testing services to most physician groups.The FTC also filed an action in federal court to prevent LabCorp from integrating the Westcliff assets while the case is being tried in the administrative court. The federal court denied the FTC motion for an injunction pending appeal. Staff filed an emergency motion for an injunction pending appeal with the 9th Circuit, which denied the Commission's appeal. The Commission dismissed its complaint and closed the investigation.
