Patent ID: 11169141

Abstract:
The invention relates to a method of detecting a clot in a measurement chamber of a liquid sample analyzer, wherein the liquid sample analyzer comprises at least two analyte sensors, a first analyte sensor, for measuring a first analyte in a liquid sample, and one or more second analyte sensors, for measuring one or more second analytes in the liquid sample in the measurement chamber, the method comprising the steps of, (a) at least partly filling the measurement chamber with a known solution having a composition comprising the first analyte at a pre-determined level, and the second one or more analytes at pre-determined levels, (b) obtaining a first sequence of measurement results by the first analyte sensor, and simultaneously obtaining a second sequence of measurement results by the second, one or more analyte sensors, (c) determining a change of the first sequence of measurement results, (d) determining a change of the second one or more sequence of measurement results, (e) comparing the change of the first sequence of measurement results with the second sequence of measurement results, (f) determining presence or absence of a clot in the measurement chamber based on said comparison.
