FIELD: medicine.
SUBSTANCE: for an assay, 5-7 cm3 of blood is taken, and before extraction the sample is pre-treated with 2 cm3 of 60% sulphuric acid; the extraction process is executed with 30 cm3 of n-hexane once, and gas chromatography is preceded with single treatment of n-hexane extract with 10 cm3 of concentrated sulphuric acid.
EFFECT: invention provides higher reliability of α-HCCH, γ-HCCH test results and twofold reduced time of sample preparation.
