Abstract
An aqueous control solution is disclosed for use with a spectrophotometer or photometric test strip that includes a predetermined amount of an analyte, a hydrophobic reference dye and a surfactant. In one embodiment, the aqueous control solution is applied to a photometric test strip having a chemical that oxidizes glucose and consequently forms hydrogen peroxide which reacts with an indicator dye that is also present on the strip. In this embodiment, the control solution includes a predetermined amount of glucose, an infrared reference dye, sodium dodecyl sulfate, and the indicator dye, such as sulforhodamine B.
