How to know you have acute liver failure?
- Complete blood cell (CBC) count, PT and/or international normalized ratio (INR): These tests may indicate thrombocytopenia and measures how long it takes for your blood to clot. If you have acute liver failure, your blood doesn't clot as quickly as it should.
- Hepatic enzymes: This test is to determine how well your liver function is.
- Serum bilirubin, ammonia, glucose, lactate, creatinine.
- Arterial blood gases (ABGs): These may reveal hypoxemia.
- Viral serologies
- Acetaminophen level
- Abdominal CT or MRI scan and biopsy: CT or MRI scans are often used to diagnose acute liver failure. These scans can also be used to guide biopsy and a biopsy sample is usually removed and looked at under a microscope. Tests of the liver tissue may help your doctor understand why your liver is failing.
