What Total Bile Acid/Bile Salts measures
Total Bile Acid/Bile Salts is most often requested in connection with liver function, gallbladder health and digestive system, which is why it sits within the liver function group at Wimpole Street.
Liver function tests (LFTs) measure enzymes released when liver cells are stressed (ALT, AST), enzymes linked to the bile ducts (ALP, gamma GT), the pigment bilirubin and the proteins the liver manufactures, albumin and total protein. Extended panels can add bile acids, alpha-1-antitrypsin, caeruloplasmin or fibrosis scores such as ELF and Fibrotest that estimate scarring. Together these give an indication of how the liver is coping rather than a direct picture of its structure.
Who considers Total Bile Acid/Bile Salts
- People often consider LFTs if they drink more than they would like to and want an objective look at the effect.
- Anyone carrying extra weight around the middle may check for signs of fatty liver.
- Those on statins, methotrexate, antifungals or other medicines known to affect the liver often monitor at intervals.
- Yellowing of the eyes, pale stools, dark urine or persistent itching are symptoms that prompt urgent assessment.
- A previous hepatitis infection, or a family history of liver disease, can be another reason.
Preparing for your Total Bile Acid/Bile Salts
- 1Fasting is not required for a standard liver panel, though avoiding alcohol for 24 to 48 hours beforehand gives a truer baseline.
- 2Avoid heavy exercise the day before, as muscle exertion can raise AST and give a false impression of liver strain.
- 3Bring a list of your medicines and supplements, including herbal products, because several can influence enzymes.
Sample for this test: venous blood sample (serum).
Understanding your Total Bile Acid/Bile Salts results
A rise in ALT and AST can indicate inflammation of liver cells, while a rise in ALP and gamma GT may reflect bile flow problems or, for gamma GT alone, alcohol or medication effects. Low albumin can point to longer-standing liver strain or other causes such as poor nutrition or kidney protein loss. Mild isolated elevations are common and are usually repeated after a few weeks before further tests such as viral serology or imaging are considered.
LFTs indicate stress on the liver rather than its cause; interpretation depends on your alcohol intake, weight, medicines and any symptoms.
