ABSTRACT:
An accurate, stable, liquid lipoprotein control composition is provided. The control composition of the present invention preferably comprises lipoprotein, suffactant and a divalent cation. The control may further comprise a chelating agent. It has been surprisingly found that when suffactant and a divalent cation are added to lipoprotein, it performs like native lipoprotein in human serum, i.e. not aggregated or subject to matrix effects. In addition, the control composition of the present invention is stable for up to about 5 months at room temperature (about 22.degree. C.) and up to about 12 months when refrigerated (about 2.degree. C. to about 10.degree. C.). Methods of making and using the control composition are also provided.
