Creatinine

Specimen validity assessment and urine drug testing programs depend on accurate creatinine measurement, and UTAK’s catalog includes products such as Urine Metals panels and a variety of Validity Check and Validity Control materials formulated to assess creatinine alongside parameters like specific gravity, pH, nitrites, and oxidants. These human-matrix QC products help clinical and forensic laboratories validate assay performance, ensure consistent accuracy, and support regulatory and accreditation requirements across toxicology and clinical chemistry workflows. Stock creatinine-containing controls and custom formulations tailored to specific testing panels are available to meet your laboratory’s quality assurance needs.
