How do I prepare for the test?

In order to optimize the best test results, it will be necessary to withhold some medications prior to the test day. If exercise is a trigger for your respiratory symptoms, please wear comfortable clothes and running shoes, as Dr Tilles may decide to have you run either on a treadmill or outside.
