Understanding Lab Tests for Statin-induced myopathy
Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Statin-induced myopathy is a condition characterized by muscle pain, weakness, or damage that occurs as a side effect of statin medications used to lower cholesterol. While the diagnosis is typically made through clinical evaluation of symptoms and medical history, blood testing plays an important supporting role in understanding contributing factors.
Recommended Test
Coenzyme Q10(3)
This test measures Coenzyme Q10 levels, an important antioxidant that plays a crucial role in cellular energy production within muscles. Statin therapy can decrease Coenzyme Q10 levels in muscle tissue, and this deficiency may contribute to the development of statin-induced myopathy. Monitoring these levels can help identify if supplementation might be beneficial.

Why Blood Testing is Important for Statin-induced myopathy
There isn't a single blood test to diagnose statin-induced myopathy itself, but laboratory testing is fundamental for assessing nutritional factors that may contribute to muscle symptoms. Understanding these underlying biochemical changes can help healthcare providers optimize treatment and potentially reduce muscle-related side effects.
Additional Considerations
Healthcare providers may also recommend other tests such as creatine kinase (CK) to assess muscle damage, but monitoring Coenzyme Q10 levels specifically addresses one of the underlying mechanisms that may contribute to statin-related muscle symptoms.
Important Considerations
