Electrophoresis with Densitometry
Evaluation of myocardial infarction and/or skeletal muscle damage.
TOTAL: Reference values have not been established for patients that are less than 6 years of age. Males: 6-11 years: 150-499 U/L; 12-17 years: 94-499 U/L; >or= 18 years: 52-336 U/L. Females: 6-7 years: 134-391 U/L; 8-14 years: 91-391 U/L; 15-17 years: 53-269 U/L; >or= 18 years: 38-176 U/L. ISOENZYMES: MM: 100%; MB: 0%; BB: 0%.
2 - 9 days
- CK Isoenzymes
Collect specimen in a red top tube or SST tube. Centrifuge, aliquot serum into two plastic vials and refrigerate up to 72 hours or freeze for longer storage. Specimen must be aliquoted within 2 hours of collection
Testing begins with total creatine kinase analysis (CK). If the total CK activity is <100 U/L testing is complete. CK isoenzyme electrophoresis testing will not be performed. If the total CK activity is > or =100 U/L, CK isoenzyme electrophoresis (CKEL) will be performed at an additional charge.. Test sent to Mayo Medical Laboratories.
