Got control? We’ve got you covered. UTAK Stock QCs cover 200+ spiked analytes in urine, blood, serum, and oral fluid — more than any other manufacturer. These “always available” 3rd Party QC stock products fill the gap in routine and emergent testing needs — allowing you to keep up with medical health and public safety trends.

We got you — for Pain Management and Compliance Monitoring, Clinical Toxicology, Forensic Toxicology, Drugs of Abuse, Esoteric Diagnostics, Endocrinology, Vitamins, Nutritional, Therapeutic Drug Monitoring, and Heavy Metal/Trace Element Testing.

Three laboratory glass flasks are displayed on a dark surface. From left to right: a clear flask with a capacity of 250 ml, a yellow liquid in a 125 ml flask labeled "PYREX Made in Germany," and a red liquid in the same size flask. The flasks are marked with measurement increments for precise volume reading. The background is softly blurred, focusing on the flasks.

If we don’t have it in stock, we can create it.
