Autonomic function testing

How to prepare for autonomic function testing?

If possible, do not take medications that may affect the cardiovascular system before you start the exam. In addition, you should not eat for at least 3 hours before the examination. Please also refrain on the morning of the investigation on caffeinated drinks such as tea, coffee and cola, and on alcohol and smoking. Wear comfortable clothing and sturdy shoes for examination. Please do not wear any support stockings or corsets in the morning if you wear them in everyday life. Please refrain from the examination if you are not feeling well (due to infection, fever or low blood sugar etc.). Detailed information about the procedure and the preparation of the autonomic function diagnostics is also provided in advance.
