Private Prealbumin Blood Test in the City of London

The liver is one of the body's largest and most important organs. It performs hundreds of vital functions, including filtering toxins from the blood, producing bile for digestion, storing energy, and producing proteins needed for blood clotting.

Liver conditions often develop without noticeable symptoms in the early stages. Blood tests that measure liver enzymes and proteins can help identify potential issues before symptoms become apparent.

What the Prealbumin Measures

• ALT (alanine aminotransferase) — an enzyme released when liver cells are damaged
• AST (aspartate aminotransferase) — an enzyme found in the liver and other tissues
• ALP (alkaline phosphatase) — an enzyme related to the bile ducts
• GGT (gamma-glutamyl transferase) — an enzyme sensitive to alcohol and bile duct problems
• Bilirubin — a waste product processed by the liver
• Albumin — a protein produced by the liver, reflecting its synthetic function

When This Test May Be Helpful

• Routine health screening or annual check-up
• Regular alcohol consumption
• Taking medications that may affect the liver (e.g. statins, paracetamol)
• A family history of liver conditions
• Unexplained fatigue or abdominal discomfort
• Monitoring a known liver condition
• Unexplained changes in skin colour or dark urine

Understanding Your Results

Results are typically available within 3 days" and are delivered securely.

Liver function test results show enzyme and protein levels compared to laboratory reference ranges. Mildly elevated results may occur for a number of reasons and do not necessarily indicate liver disease.

If any of your results are outside the normal range, we recommend discussing them with your GP. They can interpret the results in the context of your medical history, lifestyle, and medications.
