I want to thank you for yet another great job on a clinical project. From study’s initial contract, to PK kits, to validation and analyses, and ultimately, the final data, all was excellent as always. Happy to work with you all and I look forward to future studies.
VICE PRESIDENT, BIOPHARMACEUTICALS COMPANY
I want to express my appreciation for the professional care and extra effort of the KCAS Bio validation team. It is very evident that these team members truly care about their work and continuously strive towards excellence. I am very grateful to all of them for a thorough review of the document set before, during and after validation. My job of software validation specialist takes me to GLP labs around the world.
