Effects of urinary tract inflammation and sample blood contamination on urine albumin and total protein concentrations in canine urine samples

Abstract

Many dogs with pyuria do not have albuminuria or proteinuria; however, albuminuria may be more likely in dogs with pyuria and concurrent hematuria or bacteriuria. Hematuria may not cause an increase in UAlb concentration until it becomes macroscopic and even then may not increase the UPC ratio.
