Liver Blood Test: Everything You Need to Know
What is a Liver Blood Test?
A liver blood test, also known as a liver function test (LFT), is a diagnostic tool used to evaluate the health of your liver. It measures levels of enzymes, proteins, and other substances in the blood to detect liver damage, disease, or abnormalities.
Why is a Liver Blood Test Important?
Your liver plays a crucial role in detoxification, digestion, and metabolism. A liver function test helps diagnose conditions like hepatitis, fatty liver disease, cirrhosis, and liver infections. Early detection can prevent complications and ensure timely treatment.
What Does a Liver Blood Test Measure?
LFTs typically assess the following:
- Alanine transaminase (ALT) & Aspartate transaminase (AST): Indicators of liver inflammation or damage.
- Alkaline phosphatase (ALP) & Gamma-glutamyl transferase (GGT): Assess bile duct health.
- Bilirubin: High levels may indicate jaundice or liver dysfunction.
- Albumin & Total Protein: Essential for overall liver function assessment.
Do You Need to Fast for a Liver Blood Test?
In most cases, fasting is not required for liver function tests. However, your doctor may recommend fasting for 8-12 hours depending on additional tests being conducted.
Are Liver Blood Tests Accurate?
Yes, liver function tests are reliable indicators of liver health. However, abnormal results may require further testing or medical evaluation to determine the underlying cause.
When Should You Get a Liver Function Test?
Consider a liver blood test if you experience:
- Persistent fatigue
- Yellowing of the skin or eyes (jaundice)
- Dark urine or pale stool
- Unexplained weight loss
- Abdominal pain or swelling
- High-risk factors like alcohol consumption or a history of liver disease
Where Can You Get a Liver Blood Test?
Liver function tests are available at hospitals, diagnostic clinics, and GP practices. You can also opt for private liver blood tests for quicker results and convenience.
How Much Does a Liver Blood Test Cost?
The cost of a liver function test varies depending on the provider. In the UK, NHS tests may be free if prescribed by a GP, while private tests typically range from £30 to £100.
