BCA studies can be to varying levels depending upon the appliances used their electrode placements and frequencies of microcurrent used. A more detailed study by an advanced appliance ensures more precise results. It requires interpretation by experienced personnel. Yet, it involves more resources in the form of time and money. Online solutions using home appliances are effective for basic weight loss. High end appliances at offline centers are preferred for more complicated cases that need huge weight loss.

Bioelectrical Impedance Analysis (BIA) is a technique for determining impedance. It applies alternating electrical currents to an individual. This method calculates their water volume based on impedance measurements.
This non-invasive method involves the placement of electrodes on a person’s feet or hands or both. The device sends a low-level electrical current through the body. The amount of water in the body affects the flow of the current. BIA devices measure how this signal is impeded through different types of tissue. Muscle has high conductivity, but fat slows the signal down.
BIA measures the resistance to flow of the current as it passes through the body. It provides estimates of body water. Selected equations are used to calculate body fat from these estimates.
Household body fat scale manufacturers across the world mostly use the BIA measurement method.
Some other methods used are:
•Skinfold Calipers
•Hydrostatic Weighing
•Air Displacement Plethysmography
•Dual Energy X-Ray Absorptiometry (DEXA)
•Magnetic Resonance Imaging (MRI).
All these techniques use different processes and formulas for calculating body fat percentages. Hence, their readings usually do not match. Relative changes in value are more meaningful than the absolute value of a single measurement.
Errors may occur in BCA
The body fat percentage measured may significantly differ from the actual body fat percentage for the ensuing people:
• Elderly people
• People with a fever
• Body builders or highly trained athletes
• Persons undergoing dialysis
• Persons with osteoporosis who have very low bone density
• Persons with edema
• Children in growth stage
