Private Medical Clinic

Private Liver Function Test

Liver function testing, with a doctor interpreting the pattern of the result.

Which enzymes are raised matters more than the fact that something is. A pattern pointing at the bile ducts is a different problem from one pointing at liver cells, and mildly abnormal results are common and often harmless. Interpretation is the part that counts.

Book your LIVER FUNCTION TEST

Liver problems are usually silent until they are advanced, which is the reason to test rather than wait for symptoms. Liver function tests are also one of the most commonly misread sets of results in medicine, because mildly abnormal figures are extremely common and mostly not serious, while the pattern of which markers are raised carries the real information.

People generally test for one of four reasons: they drink more than they would like and want to know where they stand; they have been told at some point that a liver test was abnormal and never followed it up; they take medication that affects the liver; or they have symptoms such as persistent fatigue or abdominal discomfort.

Results come back in 24 to 48 hours with a GP report, and where something needs following up, further tests, imaging referral, and specialist referral are available here.

Preparation

No fasting is needed for liver function tests. Avoid alcohol for at least 24 hours before, and ideally longer, since recent drinking can raise some markers and make the result harder to interpret. Also avoid strenuous exercise beforehand, which can raise ALT independently of the liver.

Evening and Weekend Appointments

Monday to Friday, 8am to 7pm, Saturday 9:00 am to 2:00pm

Relevant where abnormal results need monitoring over months, which is the usual pattern. Twelve month minimum commitment, auto renews unless cancelled.

Who should TEST

  • You drink more than the recommended 14 units a week, or want to know the effect of how much you drink.
  • You have been told a liver test was abnormal at some point and never followed it up.
  • You take medication that affects the liver: methotrexate, some statins, certain epilepsy drugs, long term paracetamol at high dose, isotretinoin.
  • You take regular supplements, some of which affect the liver, including high dose vitamin A, green tea extract and some bodybuilding supplements.
  • You are overweight or have diabetes. Fatty liver disease associated with metabolic conditions is now the commonest liver problem in the UK, and it is not caused by alcohol.
  • You have persistent unexplained fatigue.
  • You have abdominal discomfort, particularly under the right ribs.
  • You have a family history of liver disease or haemochromatosis.
  • You have had hepatitis, or risk factors for it.
  • You have another autoimmune condition.

Understanding your LIVER RESULTS

Liver function tests measure several things, and the pattern is what carries the meaning.

  1. ALT and AST are enzymes released when liver cells are injured. Raised ALT is the commonest abnormality, and by far the commonest cause in the UK now is fatty liver rather than alcohol. The AST to ALT ratio helps distinguish causes: alcohol tends to raise AST more, fatty liver tends to raise ALT more.
  2. ALP and GGT rise when bile flow is obstructed or irritated. GGT is particularly sensitive to alcohol, which is why it matters for anyone testing for that reason, and it also rises with certain medications.
  3. Bilirubin is the pigment that causes jaundice when it accumulates. A mildly raised bilirubin with otherwise normal results is often Gilbert’s syndrome, a harmless inherited variation affecting several per cent of people that needs no treatment at all. Being told this rather than left to worry is genuinely useful.
  4. Albumin is a protein the liver makes, and a low level suggests longer standing impairment rather than recent injury.

On mildly abnormal results, which is what most people get. Mild elevations are extremely common and mostly not serious. The correct response is usually to identify the likely cause, address it, and repeat the test in a few weeks or months rather than to escalate immediately. Panicking about a slightly raised ALT is a common and avoidable source of distress.

On fatty liver, since it is now the most likely answer. Metabolic dysfunction associated fatty liver disease affects a large share of the UK population, is linked to weight, insulin resistance and diabetes, and is often symptomless. The good news is that it responds well to weight loss, and modest weight loss produces disproportionate improvement in liver markers. This is one of the areas where a blood test genuinely does change behaviour and behaviour genuinely does change the blood test.

On alcohol, honestly. If you are testing because you are worried about your drinking, that is a sensible thing to do and there is no judgement in it. Liver markers can improve substantially within weeks of reducing intake, and normal results do not mean drinking is harmless, since alcohol causes harm well beyond the liver. If you would like support with drinking, we can discuss it, and free NHS and charity services are available too.

On what these tests do not do. They do not exclude all liver disease. Significant fibrosis or even cirrhosis can exist with normal blood tests, which is why persistent risk factors or symptoms may warrant imaging or a fibrosis score regardless of the numbers.
