摘要： A method for measuring a glucose concentration in whole blood uses a reagent test strip having a matrix pad and a reflectance meter. The test strip is placed in the meter, and a blood sample is applied to the top surface of the pad. As the sample travels through the pad, glucose in the blood reacts with reagent in the pad to cause a change in reflectance of its bottom surface. An incubation period is initiated when the meter detects that at least a portion of the sample has reached the bottom surface. At the end of the incubation period, the reflectance of the bottom surface is measured and used to calculate the glucose concentration.

摘要： A whole blood glucose test strip for measuring glucose in an unmeasured whole blood sample is described, the test strip being adapted for use in a reflectance reading apparatus capable of measuring reflectance at two different wavelengths. The test strip comprises a porous, hydrophilic matrix having a sample receiving surface adapted to receive the whole blood sample on one side of the matrix and a testing surface from which diffuse reflected light is measurable from the other side of the matrix, wherein the testing surface is opposite to the sample receiving surface. The matrix is substantially reflective in the absence of applied sample, and contains openings of a size sufficient to allow the flow of at least a portion of the blood sample through the matrix from the sample-receiving surface to the testing surface. The matrix comprises glucose oxidase, peroxidase, and a dye precursor for chemically reacting with glucose to create a change in reflectance in the presence of optically visible hemoglobin observable from the testing surface which change is indicative of the concentration of glucose present in the sample. The dye precursor comprises 3-dimethylaminobenzoic acid and 3-methyl-2-benzothiazolinone hydrazone hydrochloride.

摘要： A method for determining the presence of an analyte in a fluid is described along with various components of an apparatus specifically designed to carry out the method. The method involves taking a reflectance reading from one surface of an inert porous matrix impregnated with a reagent that will interact with the analyte to produce a light-absorbing reaction product when the fluid being analyzed is applied to another surface and migrates through the matrix to the surface being read. Reflectance measurements are made at two separate wavelengths in order to eliminate interferences, and a timing circuit is triggered by an initial decrease in reflectance by the wetting of the surface whose reflectance is being measured by the fluid which passes through the inert matrix. Repeatability is insured by a normalization technique performed on the light source before each reading, and an alignment method operated on the reagent strip prior to emplacement on the apparatus. The method and apparatus are particularly suitable for the measurement of glucose levels in blood without requiring separation of red blood cells from serum or plasma.

摘要： A method for measuring analyte concentration in a body fluid involves taking reflectance readings from a first surface of a porous reagent-containing matrix both before and after a sample of the fluid has been applied to a second surface of the matrix. A sequence of reflectance measurements is initiated upon a predetermined drop in reflectance, which indicates that sample has reached the first surface. The analyte concentration is calculated from the sequence of reflectance measurements.
