Implication

Comparative assay evaluation reveals immunoinhibition provides rapid, cost-effective CK-MB testing in cardiac patients, indicating its suitability over immunoprecipitation for routine clinical use.

Key Points

To compare the performance and clinical utility of immunoinhibition and immunoprecipitation assays in measuring creatine kinase MB (CK-MB) and differentiating abnormal CK isoenzymes.
Analyzed serum samples from 53 healthy individuals, 55 patients with elevated CK-MB from acute myocardial infarction, and 42 patients with atypical CK variants detected via electrophoresis.
Identified atypical CK forms from a screening cohort of 5,000 hospitalized and clinic patients.
Atypical CK variants (macro CK types 1 and 2, elevated free CK-BB, and persistent CK-MB without infarction) occurred in less than 2% of screened patients and were rare in myocardial infarction.
Immunoinhibition delivered rapid, sensitive, automatable, and cost-effective CK-MB quantification, whereas immunoprecipitation provided higher analytical specificity at the expense of speed and cost.
