What Is Cholestasis?
8. How Is Cholestasis Diagnosed?
A physical exam and a blood test are the first steps a doctor takes to diagnose cholestasis. If the physician notices signs of jaundice, this will warrant further investigation. The blood draw measures the patient’s bilirubin level and tests for the enzyme’s alkaline phosphate and gamma-glutamyl transpeptidase since high levels of these are indicators of cholestasis.
While the blood test can help doctors make a cholestasis diagnosis, this does not reveal whether the issue is within the liver or outside of it. Imaging tests, such as a CT scan, ultrasound, or MRI can reveal any blockages or abnormalities. Evidence of recent drug use can also help doctors determine if problems are a result of liver disease.
