Liver
11 markers in this category
ALP (Alkaline Phosphatase)
You got your blood results back and there is an ALP on them. The number sits just outside the line. Alkaline phosphatase is an enzyme that comes mainly from your liver and your bones. That is the awkward part: the result itself does not reveal which of the two. This page answers the question you probably arrived with. What does this number mean, how high can it go, and what does your GP do next.
ALT (Alanine Aminotransferase)
What is ALT exactly? It is an enzyme that sits mainly in the liver, in full alanine aminotransferase. If it is in your blood, liver cells have been damaged. In men anything under 45 u/l is normal, in women under 34. Do you see a number like 14, 16 or 22? That sits comfortably inside the normal ALT value. A mildly raised number is common and has several causes. Usually that is no reason to panic, but it is a reason to look further.
AST (Aspartate Aminotransferase)
AST is an enzyme that ends up in your blood when cells are damaged somewhere. You find it in your liver. But equally in your muscles, your heart, your kidneys and your red blood cells. So a raised AST does not automatically mean something is wrong with your liver. The causes, ordered by how often they occur: exercise, alcohol, fatty liver, medication, and the blood draw itself. The upper limit is 35 u/l for men and 31 u/l for women.
Albumin
Albumin is a broad indicator of liver, kidney, and nutritional health. Including it in your health screening provides foundational insight into overall well-being.
Amylase
Amylase testing provides insight into pancreatic and digestive health. Regular monitoring supports early detection of pancreatic conditions.
Bilirubin (Direct)
Direct bilirubin testing provides insight into your liver's ability to process and excrete waste products. Regular monitoring supports early detection of bile duct or liver conditions as part of proactive health management.
Bilirubin (Total)
Total bilirubin is a fundamental marker of liver function and red blood cell health. Regular monitoring helps detect potential liver or blood conditions early, supporting informed and proactive health decisions.
GGT (Gamma-Glutamyl Transferase)
GGT is one of the most sensitive liver enzymes available for health screening. Regular monitoring helps detect bile duct and liver issues early, supporting proactive and informed health management.
LDH (Lactate Dehydrogenase)
LDH is an enzyme found in almost every cell in your body. Its full name is lactate dehydrogenase (LDH). This test measures how much LDH your blood contains. When cells break down, LDH spills into your bloodstream. So a raised LDH means cell damage happened somewhere. It does not say where, and it says nothing about how serious it is. A normal value sits around 120 to 250 U/L in most laboratories. If your result is higher, the cause is far more often harmless than serious.
Lipase
Lipase testing provides a specific assessment of pancreatic function. As the preferred marker for diagnosing pancreatitis, regular monitoring supports early detection and informed health decisions.
Liver Function Test (LFT)
A liver function test offers a comprehensive overview of how well your liver is performing. Regular screening helps detect potential issues early and supports proactive, informed health management.
