PCT No. PCT/SE90/00273 Sec. 371 Date Oct. 16, 1991 Sec. 102(e) Date Oct. 16, 1991 PCT Filed Apr. 24, 1990 PCT Pub. No. WO90/12890 PCT Pub. Date Nov. 1, 1990A sample of whole blood is contacted with a reagent which by chemical reaction with glucose in the sample brings about a detectable dye concentration change (10) the size of which is determined as a measure of the glucose content of the sample. The sample is initially introduced undiluted in a microcuvette having at least one cavity for receiving the sample. The cavity is internally pretreated with the reagent in dry form, and the chemical reaction takes place in the cavity. Active components of the reagent comprise at least a hemolyzing agent for exposing glucose contained in the blood cells of the sample for allowing total glucose determination, and agents taking part in the chemical reaction and ensuring that the dye concentration change (10) takes place at least in a wavelength range (14) outside the absorption range (12) of the blood hemoglobin. An absorption measurement is performed in said wavelength range directly on the sample in the cuvette. A pretreated disposable cuvette with such a reagent and a photometer are also described.
