Method development for determining prekallikrein activator in medicinal preparations of human immunoglobulins and albumin found that the adequacy of chromogenic determination of prekallikrein activator depends on the activity of the used prekallikrein reagent, the quantitative component ratio in the reaction mixture and its incubation time, and the concentration of employed chromogenic reagent. Acceptance criteria for commercial prekallikrein reagents are justified. The main method parameters and validation test results confirming the linearity in the range 0 – 35 IU/mL, accuracy, and intralaboratory precision are presented and correspond to those for biological analytical methods. The elaborated method can be used for quality assessment of prekallikrein activator content in medicinal preparations of human immunoglobulins and albumin.
