BISMUTH, BLOOD

Bismuth, Blood

What it is

The Bismuth Blood Test measures the level of bismuth in the bloodstream. Bismuth is a heavy metal used in certain medications, such as bismuth subsalicylate for digestive issues. While generally safe in low amounts, excessive exposure or prolonged use can lead to bismuth accumulation and toxicity.

Uses

This test is used to detect bismuth exposure or poisoning, monitor patients taking bismuth-containing medicines, and evaluate cases of suspected heavy metal toxicity. It helps doctors assess if bismuth levels are within a safe range.

Symptoms That May Lead to the Test

Doctors may order the test if patients show signs of bismuth toxicity, such as headache, confusion, memory loss, mood changes, blackened gums, kidney problems, or neurological issues. It is also useful for patients with prolonged use of bismuth-based drugs.

Abnormal Results

High Bismuth Levels: May indicate bismuth toxicity, often from overuse of medications or occupational exposure. Symptoms can include neurotoxicity, kidney dysfunction, and gastrointestinal disturbances.

Normal/Low Levels: Suggest safe or no significant exposure to bismuth.

Risks

The test is performed on a routine blood sample. Risks are minimal and may include mild pain, bruising, or bleeding at the puncture site, and rarely dizziness or infection.
