8 Preliminary Instructions
8.1 Participant should respect the following instructions in order to minimize
changes in the body’s hydration status (as this can over or underestimate
values):
8.1.1 Excessive exercise should be avoided 2 hours prior to measurement
to avoid changes in vascular perfusion, temperature, cutaneous blood
flow, vasodilation, and fluid losses.
8.1.2 Refrain from drinking excessive alcohol within 12 hours prior to BIA.
8.1.3 Also, the following situations affect body water concentration:
i. just prior, during, just after menstruation
ii. use of diuretics
iii. renal or heart failure
9 Preparation Prior to Test
9.1 Evaluator must plug device at least 15 minutes in advance to ensure battery
is charged for evaluation.
9.2 Check that participant has followed preliminary test instructions.
NOTE: Device will automatically shut-off after a period of inactivity.
10 Test Procedure
10.1 Ask participant to turn off mobile phone.
10.2 Ask participant if they want to go to the washroom. Measure height
(nearest 0.5 cm) and weight (nearest 0.1 kg).
10.3 Remove all jewelry, stockings, pantyhose, and/or socks.
10.4 Lie participant on their back on table feet shoulder width apart.
Measurement should be taken within 10 minutes of the participant lying
down. There is evidence that impedance values rise sharply within the first
10 minutes after the participant assumes the supine position and then
continue to rise more gradually for up to 4 hours.
10.5 Extend their arms by their side with palms down, legs slightly apart (if
necessary, place towel between participant’s legs or arms and torso in
order to prevent skin-to-skin contact and reduced impedance).
10.6 Using the anatomical locations shown below shave the sites, if necessary.
