Abstract

It is well known that in subfractional compound of blood serum (or plasma) numerous shifts with correlated character specific for a particular nature of the disease may arise during diseases varying by etiopathogenesis. A large arsenal of electrophoresis, chromatography and sedimentary methods is used in clinics-laboratory practice for diagnostics of the character of subfractional shifts. Without discussing diagnostic informational capacity of each method in use we could observe just a few principal difficulties: 1. Each method identifies a nature of ingredients of blood plasma/serum in a quite narrow interval of their molecular sizes. 2. A large amount of blood is necessary for making most part of investigations. 3. Hard and long preparation procedures are being used for making investigations. 4. Full information on subfractional compound of biological fluid may be got only with combined use of the methods mentioned above.
