The reagent contains an "accelerator" (caffeine) to solubilize unconjugated bilirubin, together with a diazonium salt (2,5 dichlorophenyl-diazonium-tetrafluoroborate), in the presence of surfactant to avoid protein precipitation, in a weakly acid medium (pH 5).
It is comprised of reducing the average particle size of the pigment in a solvent and introducing at least one surfactant or polymer comprising at least one group and having at least one primary amine, a nitrite and an acid in sufficient amounts together, or in any combination, to generate a diazonium salt comprising at least one group, wherein at least one portion of the surfactant or polymer absorbs onto at least a portion of the pigment.
