Urine Specific Gravity in Canine: Whole or Supernatant Sample?
Keywords:
specific gravity, refractometer, dogs
Abstract
The ability to concentrate and dilute urine is one of the first functions that are lost as a result of tubular damage Specific gravity by refractometry is a method used to evaluate this function Some authors mention that the reactive sediment as well as the presence of large amounts of high molecular weight substances can give an overestimation of the value of the specific gravity and recommends centrifuging the sample to obtain a reliable value In the study 123 urine samples and their specific gravity were evaluated before and after centrifugation This in order to evaluate if the presence of reactive sediment glucose and protein affected the value of the density and to obtain a reliable estimate in clinical practice No significant difference was found between pre and post-centrifugation specific gravity measurement with portable refractometer W 8058 5 p-value 0 3759 However since the interpretation of specific gravity is a categorical variable 8 of 123 samples evaluated showed changes but only one change in their categorization The findings found are important for the clinical assessment of outpatients or when a small amount of sample is available allowing refractometry to be a reliable method without the need to centrifuge the urine to obtain the parameter
