This test measures CK-MB, an enzyme found primarily in heart muscle.
Diagnostic Value: Elevated CK-MB indicates recent cardiac injury and helps confirm myocardial infarction when interpreted alongside Troponin.
Clinical Significance: CK-MB levels rise and fall quickly, making it useful for identifying reinfarction or ongoing damage.
Symptom Correlation: May align with chest pain or radiating shoulder discomfort.
The CK-MB test supports timely diagnosis of cardiac muscle injury.
