Comparing Medical Body Composition Analyzer Seca mBCA 555 With Seca mBCA 515

The mBCA 515 was compared to the gold standard methods MRI, DXA, ADP, D2O- and NaBr-dilution in previous clinical investigations (BCA-01, BCA-02, BCA-20) to generate prediction equations for calculating body composition (FFM, SMM, ECW, TBW and VAT) in different populations. Furthermore, normal ranges for body composition were generated based on the previous study BCA-03 conducted at the UKE. The mBCA 555 is a new body composition analyzer measuring bioimpedance in standing position developed by seca. In order to apply prediction equations and normal ranges from previous clinical investigations BCA-01, BCA-02, BCA-03 and BCA-20 to the new mBCA 555 it shall be compared to the mBCA 515.
