myoglobin normal range
Serum concentration of myoglobin increases above the normal range as early as 1 hour after myocardial infarction, and peak in approximately 4 to 8 hours after onset. Therefore, myoglobin is better suited for the early diagnosis of acute myocardial infarction (AMI).. As with all diagnostic tests, a definitive clinical diagnosis should not be based on the result of a single test, but should only be made by the physician after all clinical and labor atory findings have been evaluated. EXPECTED VALUES Normal serum myoglobin levels range from 30 to 90 ng/ml.
