Specimens that are obtained from gel tubes are not acceptable and will be rejected, as the gel absorbs the drugs and will lead to falsely decreased concentrations. Separate plasma or serum as soon as possible and no longer than 2 hours from time of collection and freeze. Send frozen specimens to In-Common Laboratories (Test ID: IMI,DESI).
