Body Composition Analyser



Medical Body Composition Analyzer


Medically valid, medically precise, medically useful. The medical Body Composition Analyzer (mBCA) by seca breaks down weight into body compartments relevant to the practice of medicine, namely, Fat Mass and Fat-Free Mass, Body Water (made up of extracellular water and intracellular water) and Skeletal Muscle Mass.

Measurements are processed by six analytical modules and presented in easy-to-understand graphics. seca has conducted validation studies that compare its measurement results with the scientific gold standard. This level of precision is found in the device itself, e.g., in the standing aid function, which guarantees that the subject is always measured in the right position, in the hand-held electrodes which prevent measurement errors and in the large glass platform which is suitable for weighing patients up to 300 kilograms.

Additional advantages include the short measurement time of less than 20 seconds and the simple and intuitive navigation of the touch-screen display. In brief, the seca mBCA is the best help for the diagnosis of many diseases such as current epidemics of obesity, diabetes or malnutrition.

The PC software seca analytics mBCA 115 for expanded analysis.

The PC software seca analytics mBCA 115 does more than deliver the examination results from the seca mBCA to your PC. It offers some additional and significant advantages.

Expanded analysis with the six modules.

The six analytical modules offer innumerable diagnostic options such as fat mass to weight or extracellular to intracellular water – and therefore, the doctor can now obtain indications of medical disorders which were previously difficult to diagnose without additional examinations.



1.  Energy Module

The module Energy provides data on the energy stores in the body not only in absolutes, but also as a relative value of fat mass to weight. It can also calculate the resting energy and total energy expenditure.

  • Fat mass (FM/%FM)
  • Energy stores in body
  • Resting energy expenditure (REE)
  • Total energy expenditure (TEE)






2.  Fluid Module

The Fluid module determines TBW and its makeup in terms of extra- and intracellular water. If the proportion of extracellular water is too high, that could represent that the patient is retaining water. With the help of the Bioelectrical Impedance Vector Analysis (BIVA), the patients fluid status can be presented in easy-to-understand graphics.

  • Total body water (TBW)
  • Extracellular water (ECW)
  • Hydration (HYD) = Extracellular water/intracellular water
  • Bioelectrical Impedance Vector Analysis (BIVA)




3.  Function/Rehabilitation

The module Function/Rehabilitation ascertains the patients level of fitness, metabolic activity and training progress. The Body Composition Chart (BCC) developed by seca, which depicts the measurement points of the fat mass indices over a coordinate system, helps to determine body composition.

  • Fat-free mass (FFM)
  • Fat mass (FM/%FM)
  • Fat mass indices (FFMI/FMI)
  • Skeletal muscle mass (SMM)





4.  Health Risk

With the Health risk module, a prognosis can be made for the general health. The decisive factor is the phase angle, which permits conclusions to be drawn about the condition of the bodies cells or the entire organism. This evaluation is shown in the BIVA. The module also determines fat mass index (FMI) and fat-free mass index (FFMI) and plots the measurement points in the BCC.

  • Phase angle (φ)
  • Hydration (HYD) = Extracellular water (ECW)/intracellular water (ICW)
  • Bioelectrical Impedance Vector Analysis (BIVA)
  • Fat mass indices (FFMI/FMI)




5.  Development/Growth

The module Development/Growth allows monitoring of changes in weight, as the patients weight, height and BMI are graphically presented for each measurement.

  • Weight (W)
  • Height (H)
  • Body Mass Index (BMI)








6.  Raw impedence data

The Raw impedance data module reports the results of the Bioelectrical Impedance Analysis in raw data form so that they can be used for clinical studies. The data includes impedance, phase angle, resistance, and reactance.

  • Impedance (Z)
  • Phase angle (φ)
  • Resistance (R)
  • Reactance (Xc)
