Casandra Test Code LC32901Version 1 (DRAFT)
Performing Lab
Creatine Kinase (CK), MB
Also known as: CK-2, CK-MB
Clinical Use
Order TestUse
Confirm and monitor therapy after acute myocardial infarction
Special Instructions
Not provided.
Limitations
CK-MB levels might reflect skeletal muscle injury rather than myocardial damage. Surprisingly low baseline levels might be found in the elderly. Random single CK-MB measurements cannot definitively confirm or rule out AMI; serial measurements over time are advised in the emergency room setting and during treatment.
