METHOD FOR ACQUIRING SAMPLES FOR SPECTRAL BIOCHEMICAL BLOOD ANALYSIS Russian patent published in 2014 - IPC G01N30/02 G01N33/48 G01N33/12 

FIELD: medicine.

SUBSTANCE: method for acquiring samples for the spectral biochemical blood analysis involving preparing and drying blood serum and extracting for the chromatographic examination differs by the fact that a process of a dry matter of blood serum obtaining is performed with stirring constantly at a temperature of 50-60°C for 21-27 hours to produce the dry matter in the form of a plug compacted in the centre and coated with a superficial film; the plug is perforated with a sterile and chemically intact object; 85% methanol is added to a test tube containing the dry matter. The prepared mixture is placed into the stirring device again at a temperature of 48-52°C for 21-27 hours and compacted in a centrifuge at an acceleration of 11500-12500 g. The prepared sample is added to an auto-sampler test tube of a liquid chromatograph in an amount of 3/4 - 2/3 volumes of the test tube.

EFFECT: using the present invention enables producing chromatograms with a low-error reproducibility within one sample that is adequate to provide the analysis result reliability with the use of t liquid chromatography.
