Ethnic correction
Some studies for predicted values take into account the differences between
certain ethnic groups. However, most studies that are used for spirometry
were conducted on Caucasian subjects and are therefore most appropriate for
use with Caucasian patients.
When entering patient information, you are presented with a list of options for
four ethnic groups. In this setting, you can define the corrections for these
ethnic groups. The adjustment is made to the values for Caucasian patients.
There is an exception to this function. If specific values are available for the
chosen group of predicted values and the chosen ethnic group, they will be
used instead of the correction entered here.
The American Thoracic Society’s publication, Lung Function Testing: Selection
of Reference Values and Interpretative Strategies [8], provides guidance on
the subject of ethnic correction. This paper recommends using 88% of the
Caucasian values when testing African patients and provides general
guidance in selecting adjustments for other ethnic groups.
