What might cause a false positive result for CK-MB levels?
Understand the Problem
The question is asking about potential conditions that could lead to a false positive result in CK-MB testing, which is a cardiac biomarker used to diagnose heart conditions. Each option represents a different medical condition, and the user is likely looking for an understanding of non-coronary conditions that may affect CK-MB levels.
Answer
Muscle damage, high-dose biotin, cardiovascular diseases, tumors, immunoinflammatory conditions, heterophilic antibodies.
False positive results for CK-MB levels can be caused by muscle damage elsewhere in the body, consumption of supplements like high-dose biotin, cardiovascular diseases, tumors, immunoinflammatory conditions, and interference from heterophilic antibodies.

More Information
CK-MB is a cardiac marker used to help diagnose myocardial infarction. However, levels can be influenced by non-heart related conditions, which need to be considered to avoid misdiagnosis.
Tips
Common mistakes include assuming all elevated CK-MB results are related to heart issues and not considering other potential conditions or factors.
