LOINC long common name : PhenX - weight - measured weight protocol 021501;
LOINC short name : Measured weight proto;
LOINC description : Weight is measured using a digital floor scale. The instrument should be calibrated
daily using standardized weights, and a log of calibration results should be maintained.
For reliability, the measurements are taken in duplicate. A third measurement should
be taken if the first two measurements differ by 200 grams or 0.25 pounds. If it
is necessary to take a third measurement, the two closest measurements are averaged.
Should the third measurement fall equally between the first two measurements, all
three should be averaged. Measured weight is recommended, and self-reported weight
should only be recorded as a last resort.* Please indicate how the weight was collected
(i.e., measured vs. self-reported). In instances where both self-reported and measured
weight are collected, collect the self-reported weight first before measuring weight.
*NOTE: Self-reported weight values are considered to be less accurate. Self-reported
weight is subject to error and is used when measured weight cannot be obtained.;
