    • PROBLEM TO BE SOLVED: To disclose a test strip and a measuring device.SOLUTION: A test strip and a measuring device are provided. The test strip can be used with an electrochemical measurement instrument to accurately measure the viscosity and concentration of an analyte of a specimen. The test strip includes a first specimen path, a first electrode set, a redox reagent, a second specimen path, a second electrode set, and a reaction reagent. The redox reagent includes at least a redox pair. When the specimen enters the first specimen path, the redox pair dissolves and generates an electrochemical redox reaction for obtaining a flow time of the specimen. When the specimen enters the second specimen path, the reaction reagent is used to obtain the analyte concentration of the specimen, and the concentration of the analyte can be corrected by the flow time.

    • A method and apparatus for measuring the viscosity of a sample solution. A capillary (2) having first and second spaced apart detection windows (W1,W2) is filled with a carrier solution. A plug (4) or a continuous volume (4) of a sample solution is injected into the first end of the capillary (2) and pumped through the capillary (2) at a first pump pressure passing through the first and second detection windows (W1,W2). At least part of each detection window (W1,W2) is illuminated with a light source. Light from the light source passing through the carrier solution or the sample solution at each detector window (W1,W2) is detected using an array detector (6) comprising a two dimensional array of detector locations which generates an array detector output signal indicative of the profile of light absorbance of the sample solution plug (4) or flow front (4) passing through each detection window (W1,W2). From this the time difference between the time of detection of the sample solution plug (4) or flow front (4) at each detection window (W1,W2) is determined allowing the specific viscosity etasp of the sample solution to be calculated taking into account a known time difference between the time of detection at each detection window (W1,W2) for a plug (4) or flow front (4) of a reference sample solution whose viscosity is approximately equal to the viscosity of the carrier solution when pumped at the first pump pressure.
