Myoglobin, Quantitative, Random Urine
Use
This test measures the level of myoglobin in urine, which can be useful in diagnosing conditions that cause muscle damage, as myoglobin is released into the bloodstream when muscle is damaged. This test helps in assessing the severity of muscle injury, monitoring treatment efficacy, and diagnosing rhabdomyolysis. Elevated myoglobin levels in urine may indicate muscle trauma, muscle diseases, or myocardial infarction.
