In April 2016 the Federal Economic Competition Commission (COFECE) Investigative Authority initiated an
investigation for the probable commission of absolute monopolistic practices in the market of integral services
for laboratory studies and blood bank.(1) The investigation derived from a complaint filed by the Mexican
Institute of Social Security (IMSS), which became aware of a potential agreement between integrators to divide
among themselves the regions and packages for public tenders that IMSS had issued in 2015.
