摘要
The invention provides methods of producing a homogeneous aqueous solution capable of measuring the concentration of an ion in an aqueous sample and compositions useful for this purpose. The invention is particularly useful for measuring alkali cations of medical interest such as sodium, potassium, calcium and lithium. When a protein ladened body fluid, such as serum, is the test sample, the test composition or solution preferably includes a stabilizer such as a water miscible polymer or a detergent. The invention provides a single phase aqueous test solution which can be used on conventional analyzers including large clinical analyzers with other colorimetric diagnostic tests. No phase separation or centrifugation is required to perform the measurement.
