Equation of Kushner et al for Calculating Total Body Water from the Impedance Index

Purpose:

To estimate a person's total body water (TBW) from the person's bioelectrical impedance, height and weight.

Specialty:

Nutrition

Objective:

other testing

ICD-10:

E86

Description:

Total body water (TBW) can be estimated from a person's bioelectrical impedance, height and weight. The impedance index (height in centimeters, squared, divided by the resistance in ohms) is a significant predictor of total body water. This can be used for neonates, children and adults, both male and female.
