What Is a Bismuth Test?
The Bismuth (Bi) Level Test measures the amount of bismuth, a naturally occurring heavy metal, present in a blood or urine sample. Doctors typically order this test when they suspect bismuth toxicity, or to monitor patients who are on bismuth-containing medicines such as antacids or ulcer treatments. It is also known as the Bismuth Blood Test, Bi Level Test, or Heavy Metal Blood/Urine Test for bismuth. The sample collected is usually venous blood or a 24-hour urine specimen.
What Does a Bismuth Test Measure?
The Bismuth Toxin Test analyses the concentration of bismuth in the body. The table below outlines what each measurement reflects.
| Parameter | What It Tells You |
|---|---|
| Bismuth in blood (whole blood) | Shows current bismuth exposure or accumulation in the body |
| Bismuth in urine | Reflects how much bismuth the kidneys are excreting |
| Bismuth in serum or plasma | Used alongside blood levels to confirm exposure or toxicity |
Both blood and urine samples can detect bismuth, and the choice of sample depends on what your doctor wants to assess.
Why Is a Bismuth Test Done?
A doctor may order the Bismuth (Bi) Level Test for several reasons, ranging from suspected overexposure to ongoing medication monitoring.
Common Symptoms That May Require This Test
The following symptoms may prompt a doctor to request this test:
- Visible dark lines or discolouration on the gums (known as bismuth lines)
- Excessive salivation or swelling of the mouth lining
- Abdominal pain and nausea
- Unexplained bone fractures (pathological fractures)
- Problems with walking, balance, or coordination
- Memory changes or unusual shifts in behaviour
- A history of prolonged or excessive use of bismuth-containing medicines
- Loss of appetite
- Diarrhea
- Skin reactions
- Headaches and Fever
- Depression
- Kidney disease
- Liver damage
- Anaemia
Conditions This Test Can Help Detect
The Bismuth Blood Test can help identify or confirm the following conditions:
- Bismuth-induced encephalopathy (a form of brain dysfunction)
- Nephropathy (kidney damage) caused by bismuth accumulation
- Osteoarthropathy (bone and joint problems related to bismuth)
- Gingivostomatitis (inflammation of the gums and mouth)
- Bismuth-related colitis (bowel inflammation)
- Liver tissue damage (liver necrosis) from excessive bismuth
- Skin eruptions linked to bismuth overexposure
How to Prepare and What to Expect
Getting a Bismuth Heavy Metal Test requires minimal preparation, but a few steps will help ensure accurate results.
Do You Need to Fast?
No, fasting is not required before this test. You can eat and drink normally before your sample is collected.
Practical Tips Before Your Test
Keep the following in mind before your appointment:
- Tell your doctor about all prescription medicines, over-the-counter drugs, and supplements you are taking.
- Inform your doctor if you use bismuth subsalicylate (a common ingredient in upset stomach remedies).
- Avoid eating seafood for 48 hours before the test, as it may contain trace metals that could affect results.
- If you have recently had an imaging scan using gadolinium- or iodine-based contrast dye, wait at least 96 hours before giving your sample.
Step-by-Step Procedure
Here is what to expect during blood sample collection:
- A trained phlebotomist will clean the skin over your vein with an antiseptic.
- Blood is collected using special trace element-free tubes (royal blue-top tubes with EDTA or sodium heparin) to prevent contamination.
- A small amount of blood, typically 3 to 6 mL, is drawn from a vein in your arm.
- Gentle pressure is applied to the puncture site, followed by a small bandage.
- If a urine test is needed, your doctor will provide instructions for a 24-hour urine collection at home.
- The sample is labelled and dispatched to an NABL-accredited laboratory for analysis.
Factors That Can Affect Accuracy
The following factors may affect the reliability of your results:
- Use of collection tubes that are not certified as trace element-free
- Skin or surface contamination during sample collection
- Recent use of gadolinium- or iodine-based contrast media
- Eating seafood close to the time of testing
- Improper storage or transport of the sample
Understanding Your Bismuth Test Results
Your doctor will review your Bismuth (Bi) Level Test results alongside your symptoms, medications, and medical history. The table below shows general reference ranges.
| Parameter | Normal Range | Notes |
|---|---|---|
| Bismuth in blood (unexposed individuals) | Less than 0.5 mcg/L | No significant exposure |
| Bismuth in blood (therapeutic range) | 4 to 30 mcg/L | Patients on bismuth-based treatment |
| Bismuth in urine (unexposed individuals) | Less than 1 mcg/L | No significant exposure |
| Bismuth toxicity level | Greater than 50 mcg/L | Treatment review needed |
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 health conditions can alter how bismuth behaves in the body.
- Patients with liver cirrhosis may show significantly higher bismuth levels after prolonged exposure, as the metal tends to accumulate in the liver, bone, spleen, lungs, and heart.
- Those with pre-existing chronic kidney disease face a higher risk of bismuth accumulation and toxicity because impaired kidney function reduces the body's ability to clear the metal efficiently.
How to Maintain Healthy Levels
The following general tips support healthy bismuth clearance:
- Avoid taking bismuth-containing medicines for longer than directed, and always use them under medical supervision.
- Drink adequate water daily to support kidney function and assist natural excretion of metals.
- If your work involves bismuth alloys or related materials, follow workplace safety protocols and use appropriate protective equipment.

Frequently Asked Questions
The Bismuth (Bi) Level Test measures the concentration of bismuth in blood or urine. It is used to detect bismuth toxicity in people taking bismuth-containing medications or those exposed to bismuth through their occupation. It also helps doctors monitor patients undergoing bismuth-based therapy for conditions such as peptic ulcers or H. pylori infections.
Testing is recommended for people who show bismuth lines on their gums, have unexplained bone fractures, or have a history of heavy or prolonged use of bismuth medicines. Workers in industries that handle bismuth alloys or bismuth-containing cosmetics may also benefit from periodic testing.
Early signs include difficulty with walking, balance, or writing, along with memory changes and shifts in behaviour. Some people experience insomnia and muscle cramps. As toxicity progresses, confusion, sudden involuntary muscle movements (myoclonic jerks), and speech problems may appear. If you notice these symptoms and use bismuth-containing products, consult your doctor promptly.
Bismuth compounds are regarded as relatively low in toxicity, largely because they dissolve poorly in body fluids. However, excessive or prolonged use can lead to harmful accumulation. In most cases, stopping bismuth-containing products allows the body to recover, and toxic effects are typically reversible.
Bismuth leaves the body mainly through urine and faeces. Blood clearance occurs in two phases: an early phase with a half-life of 8 to 16 hours, and a later phase with a half-life of 5 to 11 days. This means some bismuth can linger in the body for an extended period after exposure ends.
Yes. Once bismuth enters the bloodstream, it tends to concentrate in the kidneys. It binds to a specific protein in kidney tubule cells and can remain there for months. People with pre-existing kidney conditions are at greater risk of bismuth accumulation and related kidney damage.
The test is safe and straightforward. The main risks are minor, such as a brief stinging sensation at the needle site or a small bruise that fades within a day or two. There are no significant health risks associated with the blood draw itself.
