Your visit may take anywhere from a half-hour to one and a half hours, depending on your particular type of test. On the day of your test(s), you should continue taking your medication, unless otherwise indicated by your family doctor or the ordering physician. You may have to fast depending on the type of test. For Graded Exercise Tests and EEGs, you cannot drink caffeine on the day of the test. For specific details, check with the MDU Department.

The waiting list at Joseph Brant for diagnostic testing is between one to four weeks, as the Joseph Brand MDU also serves Burlington, Waterdown and Stoney Creek. The telephone number is 905-336-4104.
