UTAK LABORATORIES, I

UTAK Laboratories Inc. is a family-owned manufacturer specializing in high-quality quality control (QC) materials for clinical, forensic, and reference testing laboratories. Founded in 1973 by toxicology chemist Larry Plutchak and headquartered in Valencia, California, UTAK has served clients in 29 countries for over 50 years. The company manufactures both stock QC materials and custom-designed controls using 100% real human matrices including urine, blood, serum, oral fluid, and hair. UTAK offers products for therapeutic drug monitoring, toxicology, drugs of abuse testing, and specialized analyte panels. The company positions itself as an independent QC partner that eliminates the need for labs to establish internal manufacturing, reducing compliance risk, overhead, and labor burden while providing audit-ready documentation, certificates of analysis, and stability data. Rapid turnaround (approximately 15 days for custom formulations) and conversion of successful formulations to stocked inventory support recurring supply relationships. UTAK serves university hospitals, medical centers, forensic labs, and reference laboratories, including tier-one clients such as Quest Diagnostics.
