Urine: dipstick analysis

Contributor(s): Annalisa Barrelet, Frank Taylor

Overview

  • Changes in chemical and physical characteristics of urine occur in many diseases and include urinary tract disease, hepatic disease, hematologic disorders, endocrinopathy, neoplasia, musculoskeletal disease and hepatic encephalopathy   Behavior: ataxia  .
  • These changes in characteristics can predict disease.
  • Therefore, used as a screening test in any ill patient.

Tests

Methodologies

  • Determine specifc gravity by refractometer.
    Dipstick specific gravity does not correlate well with refractometry
  • Rapid, complete immersion of the dipstick with immediate shaking off of excess urine as well as holding the dipstick level is needed to avoid run-off between pads.
  • Compare the color change of dipstick with the reference range at the correct time.

Availability

  • Can be performed in-house by most veterinary clinics.
  • All external laboratories.

Technique (intrinsic) limitations

  • Reliable urine specific gravity reading.

Technician (extrinsic) limitations

  • Following the same approach for every analysis results in consistent findings and allows the technician to develop experience.
