Creatine Kinase (CK) Blood Test – $27

A Creatine Kinase (CK) test measures the level of this enzyme in your blood. CK is found primarily in muscles (including heart muscle) and brain. When muscle tissue is damaged, CK is released into the bloodstream.

What This Test Measures

Creatine Kinase (CK/CPK):
An enzyme that helps produce energy for muscle contraction. Total CK measures all forms combined. Different forms (isoenzymes) come from different tissues: CK-MM (skeletal muscle), CK-MB (heart), CK-BB (brain).

Reference Ranges

• Men: 39-308 U/L
• Women: 26-192 U/L

Note: Values can be significantly higher after strenuous exercise.

Who Should Consider This Test

• Muscle pain, weakness, or tenderness
• Suspected rhabdomyolysis (muscle breakdown)
• Monitoring statin medication side effects
• After intense exercise or physical trauma
• Evaluating muscle diseases (muscular dystrophy)
• Chest pain (along with cardiac markers)

What Elevated CK May Indicate

Muscle-Related:
• Intense exercise or physical labor
• Muscle trauma or injury
• Rhabdomyolysis
• Muscular dystrophy
• Myositis (muscle inflammation)
• Statin-induced myopathy

Other Causes:
• Heart attack (CK-MB rises)
• Surgery
• Intramuscular injections
• Hypothyroidism
• Certain medications

Important Note About Exercise

Strenuous exercise can elevate CK significantly for 24-72 hours. Avoid heavy exercise for 2-3 days before testing for most accurate baseline results.
