Liver Check

A blood test which looks for signs of inflammation and damage to the liver which could indicate liver disease.

Our Liver Check (also known as a Liver Function Test) is a comprehensive examination of liver enzymes such as gamma GT (GGT), alanine transferase (ALT) and aspartate transferase (AST) which can be elevated if the liver is inflamed or if the biliary system is obstructed.  

The main causes of liver disease are excessive alcohol or calorie consumption and virsuses such as hepatitis. Fatty liver disease is also on the rise due to increasingly unhealthy lifestyles. Our Liver Check can help you to determine whether your lifestyle is damaging your liver. If caught early, liver inflammation can be recovered before it causes irreversable damage. 

Our Liver Check blood test also includes tests for kidney function, gout and cholesterol. 

Who is this blood test for

As well as for people monitoring an existing liver condition, the Liver Check is designed for those who want to find out if their lifestyle is damaging their liver - particularly if they are worried about excessive alcohol, calorie or drug consumption. Early detection of liver damage means that preventative action can be taken before deterioration becomes irreversable.

The early stages of liver disease often have no specific symptoms with some signs easily confused with other problems.

Early symptoms can include:

  • fatigue and lethargy
  • loss of appetite
  • unexplained weight loss
  • unusual coloured urine and stools
  • general feeling of being unwell

What's included

Bilirubin is a product of haemoglobin breakdown. It is removed from the body via the liver, stored and concentrated in the gall bladder and excreted into the bowel. Raised bilirubin can cause the skin and whites of eyes to become yellow (jaundice) as the liver is unable to remove sufficient bilirubin from the blood. This can indicate liver damage.

Bilirubin can also be raised due to a blocked bile duct as well as Gilbert's syndrome.

Alkaline Phosphotase (ALP) is an enzyme located mainly in the liver and bones. High levels can indicate bone or liver disease. Raised ALP is looked at in conjunction with other liver function tests to determine whether the problem lies in the liver or the bones.

Pregnancy can also cause raised ALP and it is often elevated in growing teenagers.

Aspartate Transferase (AST) is an enzyme created mainly by the cells of the liver and the heart. Any injury to the heart or liver, and other bodily tissues will cause AST to be released into the bloodstream. Levels can be raised following a heart attack, or from liver damage caused by alcohol, drugs or viruses (hepatitis).

AST can be raised after vigorous exercise.

Alanine Transferase (ALT) is an enzyme which is produced by the liver and can indicate liver damage caused by alcohol, drugs or viruses (hepatitis). Small amounts of ALT are normal, but raised levels may mean that your liver is inflamed.

Raised levels can also be caused by recent vigorous exercise.

CK (Creatinine Kinase) is a muscle enzyme which measures muscle cell damage and death. CK levels tend to be higher in people with greater muscle mass.

CK levels are measured to assess muscle damage, CK levels can rise rapidly after muscle trauma, but will subside as the damage repairs. Levels which continue to rise indicate that muscle damage is continuing. If you have been to the gym the day before your blood test you may well have raised levels of CK.

Gamma GT is a liver enzyme which is raised in liver and bile duct diseases. It is used in conjunction with the ALP to distinguish between bone or liver disease. Gamma GT is used to diagnose alcohol abuse as it is raised in 75% of long term drinkers.

Sodium is both an electrolyte and mineral. It helps regulate the water (inside and outside the body's cells) and electrolyte balance of the body. Sodium is also important in how nerves and muscles work. Sodium in the blood is regulated by the kidneys. 

Too much sodium in the blood is often due to dehydration but can be a marker of the kidneys not working properly. 

Too little sodium is often caused by fluid retention (oedema) or too much sodium lost through vomiting and diarrhoea or excessive sweating. 

Urea is waste product produced as the body digests protein and is carried by the blood to the kidneys, which filter the urea out of the blood and into the urine.The urea test shows how well the kidneys are working.

A high amount of urea in the blood may indictate dehydration or that the kidneys are not working properly or simply that you consume a high protein diet. 

Low amounts of urea in the blood may indicate a low protein diet, over-hydration, malnutrition or liver failure. 

Creatinine is a chemical waste molecule that is generated from muscle metabolism. Measurement of this is an indicator of the level of other waste products. Creatinine is an accurate marker of kidney function.

Elevated creatinine can be caused by high intake of animal protein, taking creatine supplements and vigorous exercise but could also indicate that the kidneys are not working properly.

Low creatinine can be caused by a low protein diet, reduced muscle mass or merely efficient kidney function. 

Total Protein represents the sum of albumin and globulin. It is more important to know which protein fraction is high or low than what the measure of total protein is.

Albumin is made mainly in the liver and helps keep the blood from leaking out of blood vessels. It also helps carry some medicines and other substances through the blood and is important for tissue growth and healing.

Low albumin levels can indicate liver disease and can also be a marker for chronic ill-health, malnutrition and chronic inflammation. It can also occur in kidney conditions such as nephrotic syndrome and diabetes.

Raised levels are usually caused by dehydration. 

Globulin consists of different proteins and is made by the liver and the immune system. Certain globulins bind with haemoglobin while others transport metals, such as iron, in the blood and help fight infection.

Calcium is the most common mineral in the body and one of the most important. The body needs it to build and repair bones and teeth, help nerves work, make muscles squeeze together, help blood clot, and help the heart to work. Vitamin D is essential to absorb calcium.

The majority of calcium in the body is stored in bone, the rest is found in the blood. If the calcium result is abnormal, a Corrected Calcium calculation is carried out to provide further information.

Around half of the total calcium in your blood is bound by albumin. This estimates your calcium measurement if albumin levels were a specified normal value. 

Uric acid is a waste product of protein digestion. High levels can lead to excess uric acid being deposited as crystals in the tissues of the body. When this occurs in joints it causes the painful condition known as gout. 

Uric acid levels are best tested 6 weeks after symptoms appear as they may not be raised at the beginning of an attack. 

 

The Iron test meausres how much iron is in your blood with the aim of identifying iron deficiency anaemia or iron overload syndrome (haemochromatosis)

The symptoms of too much or too little iron can be similar: fatigue, muscle weakness, moodiness and problems concentrating.

A raised result can mean that you have iron overload syndrome, an inherited condition where your body stores too much iron, or that you are over-supplementing or that you have a liver condition.

A low result can mean that you are anaemic or are suffering from gastro-intestinal blood loss (or other blood loss). Anaemia is also very common in pregnant women.

Total Iron Binding Capacity (TIBC) is a measure of the amount of iron that can be carried through the blood. 

A raised TIBC result usually indicates iron deficiency whereas a low TIBC can occur with iron overload syndrome (haemochromatosis).

Transferrin is made in the liver and is the major protein in the blood which binds to iron and transports it through the body.

Low levels of transferrin indicate iron deficiency while high levels indicate iron overload.

Cholesterol is an essential body fat (lipid). It is necessary for building cell membranes and for making several essential hormones. Cholesterol is manufactured in the liver and also comes from the food we eat. Excessive cholesterol is a risk factor for heart disease - doctors like to see levels below 5 mmol/L.

However, cholesterol is made up of both good (HDL) and bad (LDL) cholesterol so it is important to investigate a raised total cholesterol to see the cause. High levels of HDL cholesterol can cause a raised result but actually be protective against heart disease.

Triglycerides are a type of fat (lipid) that circulate in the blood. After you eat, the body converts any excess calories into triglycerides which are then transported to cells to be stored as fat. Your body releases triglycerides to be used for energy. 

Raised triglycerides are thought to be a risk factor for peripheral vascular disease (affecting the blood vessels which supply your arms and legs as well as organs below the stomach) as well a microvascular disease, affecting the tiny blood vessels around the heart.
