[Methanol and isopropanol as markers of alcoholism]

Car-drivers, who lost their licence on account of drunkeness, must be tested if the danger of alcoholism exists. The only criterion for this check is the level of bloodalcohol during this case. This check happens mostly one year later. It is proposed to analyse the blood sample immediately after measuring bloodalcohol for markers of chronic or acute abuse to differ alcoholics from persons consuming alcoholic beverages in normal mode.
