Can creatinine levels indicate muscle damage?

Yes, elevated creatinine levels can sometimes indicate muscle damage or breakdown, a condition known as rhabdomyolysis. When muscles are damaged, they release creatinine into the bloodstream, leading to higher-than-normal levels. This can occur due to trauma, intense physical activity, or certain medications. If muscle damage is suspected, your doctor may order additional tests to assess muscle function and kidney health, as rhabdomyolysis can lead to kidney damage if not treated promptly.
