#ExistCollect>Collect: Green (sodium or lithium heparin), plasma separator tube, serum separator tube.
#ExistSPECIMENPREPARATION>Specimen Preparation: SST needs to sit for 15-20 minutes for proper clot formation and to assure the absence of fibrin in the serum which can interfere with this assay. Centrifuge and remove from cells ASAP or within 2 hours of collection. Specimens must be free of all particulate matter which can interfere with the assay. Transfer 2 mL serum or plasma to an ARUP Standard Transport Tube. (Min: 0.5 mL)
#ExistSPECTRANSPORT>Storage/Transport Temperature: Frozen.
#ExistRemarks>Remarks: CK-MB is quite labile. CK-MB relative percent will be calculated only if Creatine Kinase, Total, Serum or Plasma (ARUP test code 0020010) is ordered.
#ExistConditions>Unacceptable Conditions: Specimens exposed to repeated freeze/thaw cycles.
#ExistStability>Stability (collection to initiation of testing): After separation from cells: Ambient: 8 hours; Refrigerated: 3 days; Frozen: 1 month
