Abstract

The invention relates to a process for determination of albumin in a sample containing free haemoglobin by optical measurement at at least two wave lengths. According to said process, (a) a measuring signal which is sufficiently high for determination is provided at a first measuring wave length; (b) (i) no measuring signal for albumin or (ii) a measuring signal for the albumin is provided at a second measuring wave length, said signal being smaller in comparison with the measuring signal at the first measuring wave length; and (c) at the first and the second measuring wave length a comparatively high interfering signal which is produced by reaction of haemoglobin with the test reagent used to determine albumin, and which changes in relation to time.
