What enzymes are elevated in rhabdomyolysis?
Blood tests include a complete blood count (CBC), a metabolic panel, muscle enzymes, and urinalysis. The diagnosis of rhabdomyolysis is confirmed by detecting elevated muscle enzymes in blood, which include creatine phosphokinase (CPK), SGOT, SGPT, and LDH .
Does rhabdomyolysis cause Transaminitis?
Another possible explanation is that the transaminases released during muscle injury may propagate acute hepatic inflammation. Summary: Our case highlights the association of transaminitis with elevated serum CPK levels in rhabdomyolysis despite the lack of pathologic liver injury.
What can cause elevated transaminases?
The most common causes of elevated transaminase levels are nonalcoholic fatty liver disease and alcoholic liver disease. Uncommon causes include drug-induced liver injury, hepatitis B and C, and hereditary hemochromatosis. Rare causes include alpha1-antitrypsin deficiency, autoimmune hepatitis, and Wilson disease.
Why is AST elevated in Rhabdo?
Aminotransferase abnormalities, particularly AST, are common in the setting of rhabdomyolysis. AST concentrations decrease in parallel to CPK, suggesting skeletal muscle may be a significant source of AST elevation in these patients.
Are liver enzymes elevated in rhabdomyolysis?
Many clinicians are unaware that rhabdomyolysis is often associated with elevations of aminotransferases. Elevated AST levels have been observed in 95 percent of rhabdomyolysis cases and elevated ALT in 73 percent.
Can rhabdomyolysis cause elevated bilirubin?
Conclusions: Liver dysfunction secondary to rhabdomyolysis is rare but should be considered when other causes are excluded. Prothrombin time, bilirubin levels and albumin levels may help to identify concomitant liver damage. Rhabdomyolysis is rarely reported in liver resection surgeries.
Why are aminotransferases elevated in rhabdomyolysis patients?
Aminotransferase abnormalities, particularly AST, are common in the setting of rhabdomyolysis. AST concentrations decrease in parallel to CPK, suggesting skeletal muscle may be a significant source of AST elevation in these patients.
Is there a link between rhabdomyolysis and hepatic injury?
Of course, the possibility of a hepatic cause must be considered in each case, but the recognition that abnormal aminotransferases in the context of rhabdomyolysis may not be indicative of hepatic injury may avoid an unnecessary workup.

What are the laboratory findings of rhabdomyolysis?
Laboratory findings — The hallmark of rhabdomyolysis is an elevation in CK and other serum muscle enzymes. The other characteristic finding is the reddish-brown urine of myoglobinuria, but because this may be observed in only half of cases, its absence does not exclude the diagnosis.
What should you do if your transaminase level is elevated?
NAFLD = nonalcoholic fatty liver disease. Consider gastroenterology referral for patients with persistent elevations of transaminase levels and for those who are at risk of nonalcoholic fatty liver disease progression. Repeat liver enzyme testing is not necessary in the initial workup for elevated transaminase levels.
