Storage/Transport Temperature
Room Temperature
Stability (from collection to initiation)
Separated serum or plasma should not remain at room temperature longer than 8 hours. If assays are not completed within 8 hours, serum or plasma should be stored at 2 °C to 8 °C for 12 hours.
Unacceptable Conditions
Hemolyzed specimens
Processing - HUP
Load specimen in the automated track. If manually processing, spin the tube for 7-10 minutes at 1000-1300 X G. Ensure proper separation.
Processing - PAH
Spin 7-10 minutes at 3500 rpms. Bring specimen to Chemistry. Neonates spin specimens 5000 rpms in Micro Centrifuge for 7-10 minutes.
Reference Interval
Male 0-150 years: 49-397 IU/L
Female 0-150 years: 38-234 IU/L
Clinical Significance
Measurements of Creatine Kinase are used in the diagnosis and treatment of myocardial infarction and muscle disease, such as progressive Duchenne-type muscular dystrophy.
