About the test
The Creatine Kinase Isoenzymes test is used to confirm or rule out the diagnosis of acute myocardial infarction, assess its severity, and monitor the patient's condition.
Included biomarkers & Reference ranges
| Biomarker | Reference range |
|---|---|
| Creatine Kinase BB (CK-BB) A form (isoenzyme) of creatine kinase found mainly in brain tissue. Less commonly used clinically than the heart- and muscle-specific forms. | — |
| Creatine Kinase MB (CK-MB) A form of creatine kinase found mainly in heart muscle. Historically used to help detect heart muscle damage, such as a heart attack. | — |
| Creatine Kinase MM (CK-MM) A form of creatine kinase found mainly in skeletal muscle. Elevated levels typically reflect muscle injury or strenuous exercise rather than heart damage. | — |
| Creatine Kinase An enzyme found in muscle, heart, and brain tissue. Elevated levels typically indicate muscle damage, from injury, intense exercise, or certain medical conditions. | — |
| Macro CK Type 1 A less common, larger form of creatine kinase bound to an antibody. Usually a benign finding rather than a sign of tissue damage, but can cause a persistently elevated CK result. | — |
| Macro CK Type 2 A less common, larger form of creatine kinase, typically seen in people who are critically ill; unlike Type 1, it can reflect a more serious underlying condition. | — |
