Today, we offer a wide range of comprehensive Stock QCs in urine, blood, serum, oral fluid, and hair matrices for routine reference testing while our custom-designed QCs have been used to support emergent testing trends and the development of “home brew” tests for customers seeking to create their own Lab Developed Tests (LDTs).

Founder | Larry Plutchak

Once upon a time labs made their own QC 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 labs 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.
