[Composition of blood preparations. Quantitative and qualitative properties]
Some aspects of the composition of the main blood bank products are reported and discussed. Appearance of the desired clinical effect or undesired side-effect is a consequence of qualitative and quantitative characteristics of blood derivatives. Red cell products are of different purity (leukocyte contamination and plasma content) therefore clinical effects and side-effects, including long-term consequences, are also different. Actual volume of single-donor products are in a wide range, thus the effect of quantity should be taken also into consideration. Actual practical problems will be answered adequately only in the case, if the transfusiologist knows the exact fine details of the composition and quantitative aspects of blood products.
