Abstract
Abstract Blood serum is introduced into an extraction tube filled with a premeasured extraction reagent Triglycerides are selectively extracted from the serum by an extraction reagent. The extracted triglycerides are subjected to transesterification to liberate glycerol. The triglycerides are then oxidized and treated with a color-producing reagent. The amount of color is directly proportional to triglyceride concentration which can be measured by a colorimeter.

Claim 1
Independent Claim
61 words
The method set forth in claim 1, wherein the step of filling an extraction tube with premeasured reagents is facilitated by including the preparatory steps of subjecting the reagents, which are ordinarily immiscible, to ultrasonic energy sufficient to cause a suspension of one reagent within the other; and mechanically mixing the liquids during sonification for improving the uniformity of the suspension.
