All measurements should be made on the right side of the body with the subject standing upright.
The caliper should be placed directly on the skin surface, 1-2 cm away from the thumb and finger, perpendicular to the skinfold, and halfway between the crest and the base of the fold.
A pinch should be maintained while reading the caliper. Wait 1 to 2 seconds (not longer) before reading caliper.
Take duplicate measures at each site, and retest if duplicate measurements are not within 1 to 2 mm.
Rotate through measurement sites, or allow time for skin to regain normal texture and thickness.
