MRA is an FDA-registered contract laboratory specializing in product testing, validation and contamination control remediation for Biopharma, Medical Device, Pharmacy and Cosmetic companies. Thompson Street Capital Partners acquired MRA in May 2015.

Following the closing of the transaction, Accuratus’ lab facilities will remain in Eagan, MN, and MRA’s lab facilities will remain outside of Boston.

Fran McAteer, President of MRA said, “MRA is pleased to partner with Accuratus and looks forward to expanding and integrating both companies’ services to provide leadership and further our expertise in microbiological contamination control. With patient care and infection control issues at the forefront of today’s society, growth in disinfectants, preservatives, sanitizers and new antibiotic research is accelerating, and this partnership will have the capabilities to meet these challenges.”

Alan Roth, General Manager of Accuratus, said, “This acquisition strengthens our ability to service our core antimicrobial customers while further diversifying our business service offerings to include new industries. We feel confident this transaction will create a powerful partnership between two leading microbiology labs and are thrilled to partner with MRA’s team of passionate and talented professionals.”
