METHOD FOR PREPARING BIOLOGICAL REFERENT MATERIALS FOR PRODUCING MATERIAL STANDARDS OF COMPOSITIONS OF THESE MATERIALS CONTAINING TOXIC METALS AND BIOLOGICAL MATERIAL PRODUCED BY THIS METHOD (VERSIONS) Russian patent published in 2011 - IPC C12N5/07 

FIELD: medicine.

SUBSTANCE: method involves preparing a biological referent material on the basis of a biological material of animal origin, after alimentary introduction to an animal of water-soluble lead or mercury or cadmium salts before ensuring in the biological materials of the certain lead or mercury or cadmium concentrations. Thereafter, the animals are killed by decapitation. Further, the biological material is sampled with an aliquote being analysed for the preset concentrations of toxic metals, then the biological material is packed and lyophilised.

EFFECT: invention allows improving diagnosing toxic metal poisonings and providing higher accuracy of determination of the toxic metal concentrations.
