Why Choose This Liver Function Test?

This service combines the convenience of professional home blood collection with high-quality laboratory analysis performed by a UKAS-accredited laboratory operating to ISO 15189 standards.

Unlike tests that assess only a small number of liver markers, this panel evaluates multiple aspects of liver health, including liver enzymes, protein markers and bilirubin. This broader approach provides a more comprehensive picture of liver function and metabolic health.

Results are securely delivered online, typically within 1–3 working days following analysis.

Biomarkers included – Liver Function Test

• ALP (Alkaline phosphatase): Liver Enzymes and Bile Related Markers — Alkaline phosphatase (ALP) is an enzyme present in several tissues throughout the body, especially in the liver, bones, kidneys, and digestive system. ALP plays an important role in breaking down proteins and in dephosphorylation processes. In the liver, it’s associated with bile ducts and is commonly used to help diagnose liver and bone conditions. Elevated ALP levels may indicate bile duct obstr
• Bilirubin: Liver Enzymes and Bile Related Markers — Bilirubin is a yellow pigment formed when red blood cells are broken down. It is transported to the liver, where it is processed (conjugated) and then excreted through bile. Measuring bilirubin helps assess how well the liver and bile flow pathways are functioning. Elevated levels may be seen with liver or bile duct problems (such as impaired bile flow) or with increased breakdown of red blood cel
• Alanine Aminotransferase (ALT): Liver Enzymes and Bile Related Markers — Alanine aminotransferase (ALT) is an enzyme found mainly in liver cells. When liver cells are stressed or damaged, ALT can leak into the bloodstream, which is why it’s commonly used as a marker of liver health. Elevated ALT levels may indicate liver inflammation or injury and are seen in a range of conditions affecting the liver. ALT is typically interpreted together with other liver-related marke
• Aspartate Aminotransferase (AST): Liver Enzymes and Bile Related Markers — Aspartate aminotransferase (AST) is an enzyme found in several tissues, including the liver, heart, skeletal muscle, kidneys, and red blood cells. It is involved in amino acid metabolism and can be released into the bloodstream when cells in these tissues are stressed or damaged. Elevated AST may indicate liver injury, but because AST is not liver-specific, increased levels can also be seen with m
• Gamma GT: Liver Enzymes and Bile Related Markers — Gamma-glutamyl transferase (GGT) is an enzyme found primarily in the liver that helps transport molecules across cell membranes and plays a role in glutathione metabolism. It is a highly sensitive marker used to detect liver or bile duct injury and can help distinguish between bone and liver disease when other enzymes are elevated.
• Globulin: Protein Balance — Globulin is a group of blood proteins that play important roles in the body, including transporting hormones, lipids, vitamins, and minerals. They are also key components of the immune system, with some globulins functioning as antibodies that help defend against infections. Produced by the liver and immune system, globulin levels can provide insight into immune health, liver function, and nutriti
• Total Protein: Protein Balance — Total protein is a measure that reflects the combined levels of two major blood proteins — albumin and globulin. Albumin, the most abundant protein in blood plasma, helps maintain oncotic pressure and transports various substances, while globulins play key roles in immune response, blood clotting, and other functions. Total protein levels provide important insights into nutritional status as well
• Albumin: Protein Balance — Albumin is the most abundant protein in blood plasma and is produced by the liver. It helps maintain oncotic (osmotic) pressure, keeping fluid within the bloodstream, and it also transports many substances such as hormones, fatty acids, and certain medications. Measuring albumin can provide useful information about liver synthetic function and overall protein status. Abnormal levels may be seen in
