Historically, most clinical laboratories made their own quality control material, spending valuable resources troubleshooting samples that were too often out of range. In 1973 toxicology chemist Larry Plutchak saw an opportunity to overcome this obstacle, helping laboratories fill their need for 3rd party commercial QC material. Since that time UTAK has been sourcing 100% human matrices and the purest drugs possible, to provide labs with the controls they need for every kind of analysis.
