Disulfiram is rapidly and completely reduced to diethyldithiocarbamate (DEDTC) in blood within 4 minutes of addition to human blood or plasma. DEDTC, an excellent chelator of numerous metal ions, has an in vitro half-life of approximately 70 minutes in either human blood or plasma at room temperature, but nonenzymatically degraded (especially in an acid medium) to carbon disulfide and diethylamine.
It is required that specimens be frozen within one hour of drawing blood or urine. In the event that specimens are not frozen within this timeframe the utility of the test is compromised.
