THE use of laboratory tests as an aid to the diagnosis of clinical problems has become commonplace in equine practice, and should be considered an integral part of the total management of a case. The indications for blood sampling are many and varied, but it is important to realise the limitations of laboratory results - there is no substitute for a thorough clinical examination. Clinicians should therefore guard against relying too heavily on test results for a diagnosis and, rather, clinical pathology should be used as an ancillary aid. This article reviews the interpretation of basic haematological and blood biochemical tests which are available to the equine practitioner.
