Liver Function Blood Test

The most abundant protein in blood, produced by the liver. Albumin maintains blood volume and pressure, and transports hormones, vitamins, and drugs. Low levels indicate liver disease, kidney disease, malnutrition, or chronic inflammation.

A group of proteins in blood including antibodies (immunoglobulins), transport proteins, and enzymes. Elevated globulin can indicate chronic infection, inflammation, or blood cancers. Calculated by subtracting albumin from total protein.

Measures the combined amount of albumin and globulin proteins in your blood. These proteins are essential for fighting infections, blood clotting, and transporting substances throughout the body.

Bilirubin is a substance produced during the normal breakdown of red blood cells. High levels can lead to jaundice and indicate liver or bile duct problems.

A liver enzyme that helps convert proteins into energy. ALT is found primarily in the liver, making it a highly specific marker for liver damage. Elevated levels may indicate hepatitis, fatty liver disease, or medication-related liver injury.

An enzyme found in the liver, bones, kidneys, and digestive system. Elevated ALP can indicate bile duct obstruction, liver disease, or bone disorders. It's normally higher in children and during pregnancy due to bone growth.

An enzyme found in the liver, heart, and muscles. While less liver-specific than ALT, elevated AST can indicate liver damage, heart attack, or muscle injury. The AST/ALT ratio helps distinguish between different liver conditions.

A liver enzyme sensitive to alcohol use and bile duct problems. GGT is often the first liver enzyme to rise when bile ducts are blocked. Combined with ALP, it helps determine whether elevated ALP is from liver or bone.
