Liver Tests
Your liver is one of the hardest-working organs in your body, quietly handling everything from detoxifying your blood to metabolizing nutrients. But how do you know if it’s in good shape?
Liver tests are crucial in diagnosing potential issues before they become serious. Whether checking enzyme levels or assessing liver function, these tests provide valuable insights into your liver’s health.
Alanine Transaminase (ALT) Test
Measures ALT levels, an enzyme primarily found in the liver. Elevated ALT can indicate acute liver cell damage
Aspartate Transaminase (AST) Test
Assesses AST levels, an enzyme in the liver, heart, and muscles. Increased AST may suggest liver damage or other organ issues
Serum Alkaline Phosphatase (ALP) Test
Evaluates ALP levels, an enzyme found in the liver, bile ducts, and bones. High ALP can be associated with bile flow obstruction or certain bone conditions.
Gamma-Glutamyl Transpeptidase (GGT) Test
Measures GGT levels, an enzyme produced in the liver, pancreas, and bile ducts. Elevated GGT can indicate liver disease or bile duct issues.
LFTs are blood tests that evaluate how well the liver performs its tasks. Common LFTs include:
Serum Bilirubin Test
Measures bilirubin levels in the blood. Elevated bilirubin may indicate bile flow obstruction or issues with liver processing
Serum Albumin Test
Assesses the level of albumin, a protein produced by the liver. Low albumin levels can suggest liver dysfunction
International Normalized Ratio (INR)
Formerly known as the prothrombin time (PT) test, it measures how long blood takes to clot. Prolonged clotting times may be a sign of liver disease or low levels of certain clotting factors
When specific liver conditions are suspected, additional tests may be performed:
Alpha-Fetoprotein (AFP) Test
Detects AFP, a protein produced by fetal tissue and certain tumors. This test can help assess the risk of primary liver cancer and monitor treatment efficacy.
Antimitochondrial Antibodies (AMAs
The presence of AMAs in the blood can indicate primary biliary cirrhosis, chronic active hepatitis, or other autoimmune disorders.
Serum Alpha-1 Antitrypsin Test (A1AT)
Measures levels of alpha-1 antitrypsin to help diagnose rare forms of emphysema in adults and certain liver diseases in children.
Regular monitoring through these tests can lead to early detection of liver issues, allowing for timely intervention and better management of liver health.
