Specimen Required
Patient Preparation
  
Collect
Green (sodium or lithium heparin), plasma separator tube, serum separator tube.  
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)  
Storage/Transport Temperature
Frozen.  
Unacceptable Conditions
Specimens exposed to repeated freeze/thaw cycles.  
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.  
Stability
After separation from cells: Ambient: 8 hours; Refrigerated: 3 days; Frozen: 1 month
