BLOOD WITHDRAWAL DEVICE COMPRISING COMPONENTS FOR STABILIZING THE HOMOCYSTEINE LEVEL AND/OR FOR INHIBITING THE CONTINUOUS FORMATION OF HOMOCYSTEINE IN BLOOD SAMPLES, SERUM SAMPLES OR BLOOD PLASMA SAMPLES

摘要

The invention relates to a blood withdrawal device comprising at least one vessel for collecting blood, furthermore comprising components for inhibiting the continuous formation of homocysteine in blood samples, serum samples or blood plasma samples, where the components are identified by: at least one substance selected from the group of the purine bases which are derived from the purine skeleton and which independently of one another are substituted in the 2-, 6- and 8-position by a substituent selected from the group consisting of H, OH, NH2, SH, and which, independently of one another, are substituted in the 1-, 3- and 7-position by a substituent selected from the group consisting of H and CH3, including the heteroanalogous keto-enol tautomers, preferably adenine.
