ABSTRACT:
An improved method of storing and shipping a blood serum reference composition comprising in its non-biological component from about 40 to about 85 weight percent water, from about 15 to about 60 weight percent of at least one alkylene polyol having from 2-5 carbon atoms, the remainder being chiefly at least one natural biological material selected from a group consisting of blood serum, enzyme, metabolites, electrolytes, and hormones. The improvement comprises storing and/or shipping the composition at a temperature below the freezing point thereof.
