Increases may occur post-prandially or in association with stress.
Horses with PPID are often hyperglycaemic (>5.5 mmol/l) and glucosuric. Diabetes mellitus and phaeochromocytoma are rare causes of hyperglycaemia in horses.
Hypoglycaemia is often seen in critically ill foals associated with neonatal septicaemia.
Samples for glucose assay must be taken into fluoride anticoagulant or must reach the laboratory within one hour of collection. Artefactual decreases may occur with bacterial contamination of the serum or failure to separate the serum adequately.
In adult horses glucose can be measured in an oral glucose absorption test. This is useful for the diagnosis and evaluation of intestinal malabsorption.
