Liver tests are tools. A single number rarely gives a diagnosis. Your clinician reads the pattern, your history, and sometimes more than one test together.
Blood tests
Common blood tests you may see on a report include ALT, AST, ALP, GGT, and bilirubin. Albumin, INR, and the platelet count are sometimes used to think about how well the liver is working, not only whether it is irritated.
A result outside the reference range is a reason for a conversation. It is not, by itself, a diagnosis, and a result inside the range does not prove that nothing is wrong. Trends over time often matter more than one draw.
Ultrasound and other pictures
An abdominal ultrasound is often the first picture. It can show fat in the liver, some bile-duct problems, and signs that need another look. It does not measure liver function the way a blood test does.
If the specialist needs more detail, they may discuss CT, MRI, or a biopsy. Those decisions depend on the question they are trying to answer.
Stiffness tests such as FibroScan
Transient elastography, often called FibroScan, estimates how stiff the liver is. Stiffness can rise with scarring, and also with other temporary changes. The number is interpreted with your other results. It is not a score you should use to label yourself.
Questions to ask about your results
- What question was this test meant to answer?
- Do you need the test repeated, or a different test?
- What would a meaningful change look like?
- Who explains the result if it arrives before my next visit?
Ask for a copy of results in wording you can revisit. If a portal message worries you, call the clinic rather than searching each number on its own.
