LOINC Code 62838-8: PhenX - walking - ambulation objective protocol 151001

What is this code?

LOINC codes identify tests, measurements, observations, survey items, and clinical questions in a standardized way. It is associated with the component PhenX - walking - ambulation objective protocol 151001. It is commonly used with the system or sample type ^Patient.

When is it used?

• Used in lab systems, EHRs, and clinical data exchange.
• May identify a test, observation, survey item, or clinical document request rather than a diagnosis.
• Status: ACTIVE
• Panel type: Panel
• Method: PhenX

What it does not mean

• The code identifies the observation or test, not the actual result.

Key facts

• PhenX - walking - ambulation objective protocol 151001
• An accelerometer-based pedometer is used to measure the number of steps over a desirable measurement period (for a robust assessment of free-living walking, a minimum of 3 days is recommended). The participant is asked to wear the pedometer during all waking hours of the study period. Data (number of steps per hour or per day) is downloaded from the pedometer after being retrieved from the participant. The hip placements of the pedometer (on a belt or in the front pants pocket) have been shown to yield the best walking assessments. The absolute accuracy (number of steps and or distance) may vary with different pedometers, data/signal filters used by the devices, and/or placement locations. Follow manufacturers' operation manuals for specific calibration procedures if needed. It is generally not recommended to use pedometer-predicted energy expenditure values.
