Abstract
Glucose measured in blood samples is distinguished from glucose measured in the control solutions used to test the optical instruments which make such measurements. The control solutions contain a labeling substance recognized by the optical instrument to distinguish glucose measurements made of control solutions from those made of blood samples.
Claims14
A control solution for testing the performance of an optical instrument adapted to measure the concentration of glucose in blood in proportion to the optical response of an indicator, the solution comprising:
- a labeling substance recognized by the optical instrument as identifying the presence of the control solution;
- and
- a known amount of glucose.
6-21. (canceled)
A control solution for testing the performance of an optical instrument adapted to measure the concentration of at least one analyte in a fluid sample in proportion to the optical response of an indicator, the control solution comprising a labeling substance, the labeling substance having a peak absorbance of light that is distinguishable from the absorbance of the indicator.
