Abstract
A method for estimating blood content of whole blood that includes measuring an electrical property of whole blood, diluting the whole blood with a fluid of known electrical property, measuring the electrical property of the diluted whole blood, and estimating the content of blood based on the changes in the electrical property of the whole blood before and after dilution.
