| copper sulfate method | A method for the determination of specific gravity of blood or plasma in which the blood or plasma is delivered by drops into solutions of copper sulfate graded in specific gravity by increments of 0.004, each of the bottles of solution being within the expected range of the blood or plasma sample; the specific gravity of the copper sulfate solution in which the drop of blood or plasma remains suspended indefinitely indicates the specific gravity of the sample.
