Collection: Lab-Grade Synthetic Urine | Negative Control Samples

Laboratories, universities, and device manufacturers use Upass as a stable negative control sample for urinalysis workflows: dipstick validation, reagent QC, instrument calibration, and hands-on training. Every batch is quality-checked in-house before release, and the lot number printed on every box gives your QA documentation full traceability.

Because Upass is premixed and sealed with a two-year shelf life, it removes the variability and biohazard handling of pooled human samples. Standing orders and case quantities are available through our wholesale program, or order single kits and multi-packs below. Upass is in stock, and orders placed by 3:00 PM PT Monday to Friday ship the same business day. Questions about spec sheets or bulk pricing: info@upassurine.com.
