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 at -70°C immediately after being drawn and kept frozen. If the specimens are not kept frozen, this may cause lower or negative result values.
