FIELD: measurement.
SUBSTANCE: electrochemical analytical test strip for determining an analyte (such as glucose) in a bodily fluid sample (for example, a whole blood sample) and / or a parameter of the bodily fluid sample includes a sample-entry chamber with a sample-application opening, disposed on an end edge of the electrochemical analytical test strips, as well as the first and second sample-determination chambers, each of which is in direct communication by fluid with the sample-entry chamber. Electrochemical analytical test strip also includes the first and second electrodes (such as the first and second hematocrit electrodes) located in the first sample-determination chamber, and the third and fourth electrodes (for example, working electrode and reference electrodes), located in the second sample-determination chamber. Moreover, the first and second sample-determination chambers intersect with the sample-entry chamber perpendicular to each other, and the first sample-determination chamber also crosses the sample-entry chamber along the same line. Test strip may also include a protective electrode that is housed in the sample-entry chamber, the protective electrode being electrically connected to at least one of the third electrode and the fourth electrode.
EFFECT: invention provides a reduction in the amount of analyte used, provides an intuitive procedure for applying a sample to the user, the ability to use for the production of inexpensive materials and the efficiency of filling sample-determination chambers.
