Abstract
An adequate diagnosis allows the development of specific treatment and preventive strategies for problems encountered in clinical practice. Such a diagnosis must sustain reasonable scientific challenge and needs to be founded on objective clinical and/or laboratory findings. The problem-oriented system optimises the chance of achieving this while making it possible to improve performance through self-assessment and through the development of a standard, rational, and comprehensive approach to the diagnosis of clinical problems. This system enhances the scientific aspects of veterinary diagnosis and is an effective means of incorporating laboratory support into clinical veterinary medicine.
