Older studies define rhabdomyolysis on the basis of elevated serum creatinine kinase (CK) [34], but serum myoglobin concentrations above between 368 μg/l [22] and 3865 μg/l [23] predict development of AKI more accurate [22, 35] and might be a better diagnostic parameter in view of myoglobin as nephrotoxic substance. The gene discussed is MB; the disease is acute kidney injury.
