Blood biochemistry control standard
First Claim
1. A blood biochemistry control standard for the quality control of the analytical measurement of non-gaseous blood biochemistry components comprising an aqueous suspension of red blood cells which are (a) stabilized by mild treatment with aldehyde and saline at ambient temperature whereby said cells are lyseable in water and then (b) slowly and gradually equilibrated by washing over a period of at least about five minutes with an aqueous biochemical wash solution of at least one additionally incorporated non-gaseous biochemical analyte selected from the group consisting of the following analytes in the following concentrations of clinical diagnostic significance:
- Sodium;
120 to 160 meq/lPotassium;
2 to 9 meq/lUrea;
10 to 130 mg/dlGlucose;
25 to 500 mg/dlUric acid;
2 to 12 mg/dlChloride;
80 to 130 meq/lMagnesium;
0.5 to 5 meq/lCreatinine;
0.5 to 10 mg/dlPhosphorus;
0.5 to 10 mg/dlCalcium;

Abstract
A blood biochemistry control standard for the quality control of the analytical measurement of blood biochemistry components is disclosed. The control standard comprises an aqueous suspension of red blood cells which have been stabilized by mild treatment with aldehyde and saline and then slowly equilibrated with at least one additionally incorporated non-gaseous biochemical analyte in a concentration of clinical significance.
