Abstract

A method of reducing scattered light during photometric measurements, especially during the photometric measurement of haemoglobin and a reagent for the performance of the method. To a suspension which is ready for a measurement operation there is admixed an additive which reduces the difference between the refractive index of the suspension and the mean refractive index of the suspended phase. The reagent for the photometric determination of the haemoglobin comprises a lysing agent, means for modifying the refractive index, means for stabilizing the leukocytes and a solvent. The reagent is admixed as an additive to a suspension of blood particles in an isotonic solvent.
