NOTE: On rare occasions, bacteria can be found in the sample when there are no other supporting clues or clinical signs. Moderate amount of cells or crystalline material: Dilute 1:5 with 0.9% normal saline and rerun. However, in human medicine, it is recommended that a urine culture be reported negative if no growth is present following 1824 hours of incubation.13 IDEXX Reference Laboratories performed several internal studies4 to evaluate whether the same recommendation could be made for veterinary patients. By also measuring urine creatinine levels and forming a ratio of urine protein to urine creatinine, the IDEXX UPC Ratio measures urinary protein loss while automatically correcting for variations in urine volume and concentration. If so, trust your visual interpretation of the sample and move on to a diagnosis, treatment, or follow-up appointment.
