A simplified intravenous glucose tolerance test has been developed for use in domestic cats and the results compared with those obtained using the standard test. The simplified test used two cephalic catheters, implanted in unsedated, unanaesthetised cats three hours before the test. Blood samples were collected before and after intravenous administration of glucose (0·5 g/kg bodyweight). Blood glucose concentration was measured with a reflectance glucose meter and an automated chemistry analyser. There were no significant differences between the results derived from the two tests. Because the simplified glucose tolerance test is easier to perform, requires no anaesthesia, uses only cephalic catheters and can be done on an outpatient basis, it is more cost effective and more clinically applicable. There were no significant differences between the results of glucose measurements with the two machines and the simplified glucose tolerance test can therefore be carried out with the reflectance glucose meter.
