Liver blood tests (formally known as liver function tests – LFTs)

What are liver blood tests?

Liver blood tests look at how well the liver is functioning and can indicate whether there is any damage or inflammation inside the liver.

Until recently, liver blood tests were referred to as liver function tests, or LFTs.

However, as most patients with abnormal liver blood tests actually have normal function of the liver, this term was felt to be unhelpful and often led to unnecessary concern. Therefore the term liver function tests, or LFTs, has been replaced by liver blood tests. This is a very important change, and the medical profession is working hard to ensure the new term is widely accepted and used.

Calling these tests liver blood tests is a more accurate way of describing what the test actually does and uses less frightening language.
