International Classification:

G01N 2103

US Classification:

73 5301, 73 6443, 422 73, 436 69, 356 89

Abstract:

In combination, an instrument for determining a characteristic of a biological fluid or a control, and a cuvette for holding a sample of the biological fluid or control, the characteristic of which is to be determined. The instrument comprises a radiation-reflective surface, a first source for irradiating the surface, and a first detector for detecting radiation reflected from the surface. The cuvette has two opposed walls substantially transparent to the source radiation and reflected radiation. The first source and first detector are disposed adjacent a first one of the two opposed walls. The radiation reflective surface is disposed adjacent a second of the two opposed walls. A second source is provided for irradiating the surface. The first detector detects radiation from the second source reflected from the surface. The second source is positioned to transmit radiation through the two opposed walls for reflection by the surface and transmission back through the two opposed walls to the first detector to indicate whether a sample has reached a first point in the cuvette.

International Classification:

G01N 2700

US Classification:

436 95, 436149, 436150, 436 14, 422 8201, 422 8202, 435 14, 20440301, 20440304, 20440311

Abstract:

A system for measuring a glucose level in a blood sample includes a test strip and a meter. The test strip includes a sample chamber, a working electrode, a counter electrode, fill-detect electrodes, and an auto-on conductor. A reagent layer is disposed in the sample chamber. The auto-on conductor causes the meter to wake up and perform a test strip sequence when the test strip is inserted in the meter. The meter uses the working and counter electrodes to initially detect the blood sample in the sample chamber and uses the fill-detect electrodes to check that the blood sample has mixed with the reagent layer. The meter applies an assay voltage between the working and counter electrodes and measures the resulting current. The meter calculates the glucose level based on the measured current and calibration data saved in memory from a removable data storage device associated with the test strip.
