a. In the USA, a study was conducted with 130 healthy adults of different ethnicities. The aim of the study was to validate the pa-
rameters determined using seca's in-house formulas against clinically-established reference methods. The results of this compar-
ative study are shown in the table above. The table shows the standard deviation (SEE) for the parameters determined using
seca's in-house formulas by ethnicity.
