Before the visit
Do not eat for 3–4 hours before the test. Do not schedule the test immediately after physical activity. After an intense workout, wait until your body has recovered.
Do not consume coffee or alcohol for 24 hours beforehand.
Do not go to the sauna, take a hot bath, or shower immediately before the examination. Do not apply cream or oil to your hands or feet before the measurement.
On the day before and on the day of the test, drink water as you normally would. If your doctor has prescribed a fluid intake restriction, follow it. Before the test, use the restroom and stand quietly for about five minutes.
Choose light, comfortable clothing. Before the measurement, remove any jewelry and your watch, and take any items out of your pockets.
This measurement must not be performed on individuals with a pacemaker, an implantable defibrillator, or a similar electronic life-support device.
If you are pregnant, consult your doctor about the necessity and appropriateness of the test before signing up.
Fluid levels may fluctuate during the menstrual cycle. To make it easier to compare results, it is best to schedule repeat measurements during a similar phase of the cycle.
