The myoglobin urine test is done to detect the presence of myoglobin in urine.
Myoglobin can also be measured with a blood test.
Normal Results
A normal urine sample does not have myoglobin. A normal result is sometimes reported as negative.
Normal value ranges may vary slightly among different laboratories. Talk to your provider about the meaning of your specific test results.
