Overview of the Total Bile Acid/Bile Salts Test
The Total Bile Acid/Bile Salts blood test measures the concentration of bile acids circulating in the blood, providing information about liver processing and bile flow.
The test assesses 1 specialist liver and biliary marker: Total Bile Acid/Bile Salts.
Bile acids are produced in the liver from cholesterol.
They are secreted into bile, stored temporarily in the gallbladder and released into the small intestine where they help digest and absorb dietary fats and fat-soluble vitamins.
Most bile acids are then reabsorbed through the intestine and transported back to the liver.
This recycling process is known as the enterohepatic circulation.
Only relatively small concentrations are normally present in the systemic bloodstream.
Blood bile acids can increase when the liver is unable to extract them efficiently or when normal bile flow is impaired.
They can therefore provide useful information in selected liver and cholestatic conditions.
An important clinical use is the assessment of intrahepatic cholestasis of pregnancy, where maternal bile acids can become elevated and itching may occur, frequently affecting the palms and soles.
The significance of bile acids in pregnancy depends on the measured concentration, gestational age, symptoms and obstetric context.
Bile acids can also rise in other liver and biliary disorders.
The test is not specific to one diagnosis.
It is usually interpreted alongside liver-function markers such as ALT, AST, Gamma-Glutamyltransferase, Alkaline Phosphatase and Bilirubin.
Food intake can influence bile-acid concentration, which is why the laboratory's specified collection conditions should be followed carefully.
What Does the Total Bile Acid/Bile Salts Test Check?
The test measures total circulating bile acids and can provide information about bile metabolism, liver processing and cholestasis. This test measures 1 specialist biomarker.
Total Bile Acid/Bile Salts
Measures circulating bile acids produced by the liver, supporting assessment of bile flow, hepatobiliary function and selected cholestatic conditions including intrahepatic cholestasis of pregnancy.
Who May Benefit From the Total Bile Acid/Bile Salts Test?
Total bile acid testing can be useful during investigation of cholestasis, liver disease or pregnancy-related itching.
Pregnant people with unexplained itching - Bile acid measurement is particularly important where intrahepatic cholestasis of pregnancy is being considered.
People with cholestatic liver-function abnormalities - Raised bile acids can provide additional information about impaired bile processing.
People with a previous elevated Bile Acid result - Repeat testing can establish whether the concentration remains abnormal.
People with known liver disease under specialist review - Bile acids can occasionally contribute to assessment of hepatic function.
People with suspected bile-flow impairment - Cholestasis can increase circulating bile acids.
People with abnormal Bilirubin, ALP or GGT results - Bile acid testing can provide supplementary information.
People undergoing hepatology assessment - Total bile acids may form part of a more detailed liver investigation.
People specifically advised to have bile acids measured by an obstetrician or clinician - Correct interpretation depends on the clinical indication.
How to Prepare
Do not delay maternity assessment for significant pregnancy-related itching while waiting for private laboratory testing.
Interpretation depends on whether the laboratory result is based on fasting or non-fasting collection and on the clinical context.
Symptoms and Reasons to Consider the Total Bile Acid/Bile Salts Test
Symptoms depend on the underlying condition responsible for altered bile-acid metabolism.
Itching during pregnancy - Intrahepatic cholestasis of pregnancy can cause significant pruritus, often without a visible rash.
Itching affecting the palms or soles - This pattern can be particularly relevant during pregnancy.
Jaundice or yellowing of the eyes - Impaired bile processing or flow can increase Bilirubin and may also affect bile acids.
Dark urine or pale stools - These can occur with significant cholestasis.
Abnormal liver-function tests - Bile acids can provide additional information where a cholestatic pattern is present.
A previous raised bile-acid result - Repeat testing can help assess progression or response.
Known liver disease - Specialist assessment may occasionally include total bile acids.
Pregnancy with a previous history of obstetric cholestasis - Repeat monitoring may be required under obstetric care.
New or significant itching during pregnancy should be discussed promptly with maternity services because intrahepatic cholestasis of pregnancy requires appropriate obstetric assessment.
One normal bile-acid result does not always exclude evolving pregnancy cholestasis where itching persists, and repeat testing may be required.

When Will I Receive My Results?
The current London Blood Tests catalogue lists the Total Bile Acid/Bile Salts test at £110.
The specialist laboratory turnaround is approximately 1 week after laboratory receipt.
Bile acid measurement requires dedicated biochemical analysis and laboratory quality-control procedures.
Turnaround begins when the specimen reaches the laboratory rather than necessarily from the exact time the blood sample is collected.
Understanding Your Results
A raised Total Bile Acid result indicates increased circulating bile acids.
Possible explanations include impaired hepatic uptake, cholestasis or other hepatobiliary dysfunction.
In pregnancy, elevated bile acids in someone with compatible itching can support the diagnosis and assessment of intrahepatic cholestasis of pregnancy.
The exact concentration can also influence obstetric management.
Pregnancy-specific interpretation therefore requires maternity or obstetric review.
Outside pregnancy, abnormal bile acids should be considered alongside liver enzymes, Bilirubin and other investigations.
A result within the laboratory range makes significant elevation less likely at the time of collection.
However, concentrations can change over time.
Where symptoms persist, particularly pregnancy-related itching, repeat testing may sometimes be required.
The collection conditions and laboratory's own reference limits should always be considered.
