The CK-MB Rapid Quantitative Test is designed to measure the concentration of Creatine Kinase-MB (CK-MB), a cardiac-specific isoenzyme used as a key biomarker for myocardial injury. Creatine kinase exists as three isoenzymes: CK-MM (skeletal muscle), CK-BB (brain and smooth muscle), and CK-MB (cardiac muscle).

In cases of acute myocardial infarction (AMI), CK-MB levels begin to rise within 4–6 hours, peak between 18–24 hours, and return to normal within 2–3 days, providing critical diagnostic insight into cardiac damage. The Biotime CK-MB kit ensures high analytical accuracy and rapid detection, minimizing false results caused by enzyme inversion and supporting timely clinical decision-making.

This test plays a vital role in emergency and critical care environments such as ICU, emergency departments, and cardiology units, where quick and reliable cardiac evaluation is essential.
