How do I interpret my ultrasound bone measurement report ?

BUA

This is the actual ultrasound reading in decibels/megahertz.

% EXP

This shows your results as a percentage of the measurement that is expected for a person of your age and sex.

Zu

This is referred to as a Z-Score and is a comparison of your results with other people of your age and sex.

Tu

This is referred to as a T-Score and is a comparison of your results with those of typical, young, healthy people of your sex. The T-Scoreshows the amount your bones have weakened compared to a normal 20 year old person of your sex and is shown by horizontal colored green, yellow, and red bands on the report.

Low

greater then -1SD

Moderate

between –1SD and -2SD

High

less than –2SD

A standard deviation (SD) is a measure of how widely values are dispersed from the average value (the mean). T-Score = number of standard deviations that the reading is away from young normal.
