Race Influences on Norm Values
According to the setting of the patients race the predicted values will differ. The differences
are (according to ITS recommendations) as follows:
All languages except American:
W/B W (White): values are calculated
according to the given
formulas (= 100%)
B (Black): 85% of the given formulas
American Only:
C/H/B/A C (Caucasian): values are calculated
according to the given
formulas (= 100%)
H (Hispanic): values are calculated
according to the given
formulas (= 100%)
B (Black): 85% of the given formulas
A (Asian): 85% of the given formulas
The 85% race compensation is calculated only when the following normal
values are selected: COMPOSITE; KNUDSON; CRAPO; MORRIS; POLGAR
