What is the reference range for the CK Relative Index?

The CK Relative Index, which evaluates the amount of creatine kinase (CK) present in relation to other enzymes, is essential for differentiating conditions such as myocardial infarction from muscle damage. The reference range of 0%-2.5% indicates the typical upper limit of CK activity observed in the serum for healthy individuals. This range helps clinicians interpret test results effectively, especially when assessing for potential heart or muscle issues. Values exceeding this range may signal increased CK levels possibly linked to myocardial infarction or other muscle damage.

This reference range is crucial for ensuring accurate diagnoses and can aid in the clinical decision-making process. The choice represented as 0%-2.5% appropriately captures the typical limits set for the CK Relative Index in healthy populations.
