The Displacement of Serum Water by the Lipids of Hyperlipemic Serum. A New Method for the Rapid Determination of Serum Water 1

In the course of studies on lactescence of serum, it was found that the insoluble lipids displaced se- rum water to a degree which was occasionally great enough to be of considerable practical im- portance. The immediate consequence of this displacement was the finding of spuriously low concentrations of water-soluble components of se- rum, although their concentrations were normal when repeated on sera from which the insoluble lipids had been removed by ultracentrifugation.
