A liquid control standard for the use in the quality assurance of blood analysis instrumentation systems is disclosed. The liquid control standard is able to act as a control standard for blood gas instrumentation systems measuring pH, pCO2 and pO2 of blood, as a liquid control standard for ion selective electrode instrumentation systems for the measuring of electrolytes such as ionized calcium and total calcium as well as Na, K and Li ions in the blood and, optionally, as a control standard for a co-oximeter measuring the amount of total hemoglobin present in the blood and the relative amounts of other hemoglobin fractions present in the blood. |
