Zusammenfassung:	The invention provides for a method of determine a physical property of a biological sample. The method comprises the steps of: acquiring (100) a set of preliminary calibration signals (306) of a first lot (208') of a reagent using an automatic analyzer (202) with a first photometry module (210); acquiring (102) a reference set of signals (310) of the first lot of the reagent using a calibration analyzer (302) with a second photometry module (210'); determining (104) a set of module specific components (224) by subtracting the reference set of signals (310) from the preliminary calibration signals (306); acquiring (106) a lot specific set of signals (226) of a second lot (208) of the reagent using the second photometry module (210'); determining (108) a lot calibration (228) for the first photometry module (210) using the set of module specific components (224) and the lot specific set of signals (226); and acquiring (110) a measurement signal (230) of the biological sample using the first photometry module (210) and the second lot (208) of the reagent; and determining (112) a physical property (232) of the biological sample using the measurement signal (230) and the lot calibration (228).
