While certain blood tests can be suggestive of cirrhosis, no single blood test definitively diagnoses it. Doctors typically use a combination of blood tests, imaging techniques, and sometimes even liver biopsies for a conclusive diagnosis.
Here are some of the common blood tests used in the evaluation of cirrhosis:

Liver function tests:
- Liver enzymes: These include alanine transaminase (ALT), aspartate transaminase (AST), alkaline phosphatase (ALP), and gamma-glutamyl transferase (GGT). Elevated levels of these enzymes can indicate liver damage, but they can also be elevated in other conditions.
- Albumin and bilirubin: Albumin is a protein made by the liver, and low levels can suggest cirrhosis. Bilirubin is a waste product broken down by the liver, and high levels can cause jaundice (yellowing of the skin and eyes).
- Prothrombin time (PT) and international normalized ratio (INR): These tests assess blood clotting function, which can be impaired in cirrhosis.
Other blood tests:
- Complete blood count (CBC): This can reveal anemia, a common complication of cirrhosis.
- Viral hepatitis tests: These check for infections like hepatitis B and C, which can contribute to cirrhosis.
- Autoimmune liver disease tests: These look for markers of autoimmune conditions that can affect the liver.

Advanced blood tests:
- Fibrosis scoring systems: These combine various blood tests and clinical features to estimate the degree of liver scarring (fibrosis), which can progress to cirrhosis. Examples include APRI and FIB-4 scores.
It's important to remember that these tests are not diagnostic on their own. Your doctor will consider your medical history, symptoms, and other test results to arrive at a diagnosis. If you have concerns about your liver health, please consult a healthcare professional for proper evaluation and diagnosis.
