Urine Turbidity
The turbidity of the urine sample is gauged subjectively and reported as: clear, slightly cloudy, cloudy, opaque, or flocculent.
Abnormal turbidity
The turbidity in this sample was due to numerous struvite crystals which precipitated upon cooling of the specimen to room temperature.
Normally, fresh urine is clear to very slightly cloudy. Excess turbidity results from the presence of suspended particles in the urine. The cause can usually be determined based on the results of the microscopic urine sediment examination.
Common causes of abnormal turbidity include :
  • increased cells (RBC, WBC)
  • numerous crystals
  • bacteria
  • lipiduria (lipids often rise to the surface)
  • mucus (especially in horses)
  • semen
  • fecal contamination
