What Is a Gallstone Analysis?
A gallstone analysis, also called calculus (stone) analysis or biliary calculus analysis, is a laboratory test that identifies the chemical makeup of gallstones. The stones are collected during surgery or when passed naturally, then examined in a laboratory to determine what they are made of. Doctors use the results to understand why stones formed and to guide preventive care.
What Does a Gallstone Analysis Measure?
The test identifies the type and composition of the stone rather than measuring a value against a normal range. The key components examined are listed below.
| Component | What It Tells Us |
|---|---|
| Cholesterol | The main component of most gallstones; high cholesterol content points to metabolic risk factors |
| Bilirubin (bile pigment) | A breakdown product of haemoglobin; elevated bilirubin leads to pigment stone formation |
| Calcium salts | Present as calcium bilirubinate or calcium carbonate; common in pigment and mixed stones |
| Other components | Phospholipids, fatty acids, bile acids, and trace minerals such as magnesium, iron, and copper |
The laboratory uses techniques such as FTIR spectroscopy (Fourier transform infrared spectroscopy), which classifies stones based on how they absorb infrared light, giving a precise picture of their chemical structure.
Why Is a Gallstone Analysis Done?
A cholelithiasis analysis is requested when a stone has been removed or passed naturally, and the doctor needs to know its composition. Below are the main reasons it is ordered.
Common Symptoms That May Require This Test
The symptoms below often lead to a diagnosis of gallstones and, following stone removal, may prompt a gallbladder stone analysis:
- Upper right abdominal pain, often sudden and severe
- Nausea and vomiting
- Bloating or indigestion
- Pain that spreads to the right shoulder or back
- Jaundice (yellowing of the skin and whites of the eyes)
- Fever with chills (if an infection is present)
Conditions This Test Can Help Detect
A gallstone analysis can help identify the underlying cause of stone formation and guide further investigation. Relevant conditions include:
- Cholelithiasis (gallstone disease) and its metabolic causes
- Haemolytic disorders such as sickle cell anaemia and thalassaemia, which raise bilirubin levels and promote pigment stone formation
- Liver disease, including cirrhosis, which is associated with increased pigment stone risk
- Metabolic conditions such as hyperlipidaemia (high blood fat levels) are linked to cholesterol stone formation
- Recurrent bile duct stones following gallbladder removal surgery
How to Prepare and What to Expect
Because the sample is a stone specimen collected during a procedure rather than a blood or urine sample, preparation for this test is minimal. The notes below will help you understand what is involved.
Do You Need to Fast?
No, fasting is not required for a gallstone analysis. The specimen is collected during surgery or an endoscopic procedure, and no dietary restrictions apply specifically to this test.
Practical Tips Before Your Test
The following points are worth keeping in mind before the stone is submitted for testing:
- Inform your doctor about all medications you are currently taking, as some can contribute to stone formation
- Ensure the stone specimen is stored in a clean, dry, and labelled container as provided by your healthcare facility
- Discuss any questions about the surgical or endoscopic retrieval procedure with your treating doctor before it takes place
Step-by-Step Procedure
The process from stone collection to report is straightforward and typically follows these steps:
- Gallstones are retrieved during a cholecystectomy (surgical removal of the gallbladder) or an endoscopic procedure such as ERCP (a technique used to remove stones from bile ducts).
- The retrieved stone is placed in a clean, dry specimen container and labelled with your details.
- The container is sent to the laboratory, where technologists examine the stone using FTIR spectroscopy and related methods.
- The stone is classified according to its characteristic absorption patterns, identifying its chemical components.
- A detailed report describing the stone's composition is prepared and sent to your doctor.
Factors That Can Affect Accuracy
A few factors can influence how precisely the stone is classified:
- Very small stones may be difficult to analyse thoroughly
- Improper storage or contamination of the specimen can affect results
- Gallstones with a mixed or layered structure may have an internal composition that differs from their outer surface
- Heterogeneous (uneven) stones may require sampling from multiple areas for an accurate classification
Understanding Your Gallstone Analysis Results
Results from a biliary calculus analysis describe the type and composition of the stone rather than comparing values to a normal range. Your doctor will review the findings alongside your medical history to determine the most appropriate next steps.
| Stone Type | Composition | Possible Implication |
|---|---|---|
| Cholesterol stone | More than 80% cholesterol; typically yellow-green | Associated with a high-fat or high-carbohydrate diet, hyperlipidaemia, obesity, or rapid weight loss |
| Pigment stone (black) | Primarily bilirubin and calcium salts, with less than 20% cholesterol | Associated with haemolytic anaemia, cirrhosis, or other liver conditions |
| Pigment stone (brown) | Bilirubin and calcium salts; forms in the bile ducts | Often linked to bacterial or parasitic infection in the bile ducts |
| Mixed stone | 20% to 80% cholesterol with bilirubin and calcium | Reflects a combination of metabolic factors |
These ranges are general guidelines. Your doctor will interpret your results based on your age, health history, and other factors. Always consult a qualified healthcare professional for personalised medical advice.
Results During Special Conditions
Certain conditions can influence the type of stone that forms:
- Haemolytic anaemias (conditions where red blood cells are destroyed at a higher rate than normal) significantly raise bilirubin levels and increase the likelihood of pigment stones.
- Liver cirrhosis can alter bile composition, raising pigment stone risk.
- Women have a higher prevalence of gallstones than men, a difference attributed to the effects of oestrogen and progesterone on bile composition.
How to Maintain Healthy Levels
These general lifestyle habits may help reduce the risk of stone recurrence:
- Eat a balanced diet that includes plenty of fruits, vegetables, and wholegrains, and limit foods high in saturated fat.
- Maintain a healthy body weight through gradual, sustained changes rather than rapid weight loss programmes.
- Aim for regular physical activity, which is associated with a lower likelihood of developing gallstones.

Frequently Asked Questions
After gallbladder removal or a stone retrieval procedure, a gallstone analysis provides clear evidence of why the stones formed. This helps your doctor identify your personal risk factors and advise you on steps to prevent new stones from developing.
The gallstone is retrieved during a surgical procedure (cholecystectomy) or an endoscopic procedure. Once removed from the body, the specimen is placed in a clean container and sent to the laboratory. No additional procedure is needed solely for the analysis.
A cholelithiasis analysis classifies stones into three main types: cholesterol stones (the most common, making up 37% to 86% of cases), pigment stones (2% to 27%), and mixed stones (4% to 16%). Each type points to different underlying factors.
FTIR spectroscopy (Fourier transform infrared spectroscopy) is the standard method used for calculus (stone) analysis. It identifies chemical components within the stone based on their unique response to infrared light, allowing accurate classification.
No preparation is needed. Because the sample is a stone collected during a procedure, no fasting, dietary restrictions, or special preparation is required on the patient's part before the test.
The results cannot predict future stone formation with certainty. However, knowing the stone type and composition gives your doctor useful information to recommend lifestyle changes that may lower your risk of forming new stones.
This test is recommended for anyone who has had gallstones surgically removed or passed spontaneously. It is especially useful for people who have had stones recur after previous treatment, as well as for younger patients, in whom an underlying blood or metabolic condition may need investigation.
