Description
Liver blood tests are a general check on how the liver is working, and often the first thing looked at when something non-specific is going on.
What this test measures
ALT, AST, GGT, alkaline phosphatase, bilirubin and albumin.
Who it is for
- Reviewing alcohol intake
- Long-term medication that can affect the liver
- Known or suspected fatty liver
- Unexplained tiredness, nausea, or discomfort under the right ribs
- A general baseline
Preparing for your test
No fasting required. Avoid alcohol for 24 hours and avoid heavy exercise the day before — strenuous activity raises AST and can look like a liver problem when it is muscle.
Worth knowing
Mildly abnormal liver tests are common and frequently benign, but they should never simply be ignored. Yellowing of the skin or eyes, pale stools or dark urine warrant urgent in-person assessment rather than a home test.
What happens next
Once the laboratory reports, a GP registered with the Irish Medical Council reviews your result alongside the information you gave us and explains what it means in plain English. GP review is included in the price — we do not release raw numbers without interpretation.
Important limitations
This is a screening test, not a diagnosis. A result in range does not rule out every cause of a symptom, and a result out of range does not by itself confirm a condition. If you feel unwell, see a doctor in person regardless of what this test shows. This service is not for emergencies — call 112 or 999 if you are seriously unwell.
