The introduction of a new test is often slow and obsolete tests are hard to get rid of. After nearly 20 years, the cardiac proteins troponin I and T have not yet replaced the old creatinin kinase myocardial band (CK-MB). International guidelines now recommend the use of troponin as marker for myocardial necrosis and only CK-MB when troponin is not available. However, 23 of 46 Danish laboratories still use CK-MB. The additional cost thus incurred could be used for other beneficial purposes. It is recommended to follow the international guidelines.
