Use of a Lyophilized Serum Enzyme Preparation in Quality Control

[摘要] A purified preparation of alkaline phosphatase added to standardized lyophilized serum has been used by the Minneapolis Veterans Administration Reference Laboratory to evaluate the routine alkaline phosphatase method in use in the 10 laboratories in its reference area.Evidence of a marked need for investigation of the routine method for alkaline phosphatase determination was found in 3 of the 10 laboratories.A semiquantitative phosphatase method proved to be useful as an independent procedure for use in evaluation of the different laboratories.
