PROCESS FOR THE ANALYSIS OF MEDICAL SAMPLES CONTAINING HAEMOGLOBIN

摘要

PURPOSE: Disclosed is a process for determining an analyte in a sample containing free hemoglobin. CONSTITUTION: Determination is performed by optical measurement and the value measured for the analyte concentration is corrected by calculation. The process is particularly suitable for determination of the parameters of total protein, iron and albumin in a medical sample, e.g. in a serum or plasma sample. The measured value for the analyte concentration is corrected by the following steps: (a) measurement of the blank value of the sample to be analyzed; (b) measurement of the blank value of a reference value free of hemoglobin; (c) measurement of the uncorrected value for the analyte concentration; and (d) correction of the value obtained in step (c) by correlation with the values obtained in steps (a) and (b) to obtain the corrected value for the analyte concentration.
