Define Total Body Potassium (TBK)?
Potassium in the body is an index of body's total cell mass. A gamma counter measures the amount of a type of potassium which is assumed to be a proportion of FFM. he person lies on a bed for 15 minutes. Special detectors, above and below the bed, pick up and measure the naturally-occu ing gamma signals that are emitted from the body. The equations are complex and the method is impractical and costly.
