Bismuth, Whole Blood
Also known as: BS B
Use
May be useful in the assessment of acute or chronic exposure to bismuth. Elevated blood bismuth levels can indicate exposure from various sources, and the test can aid in diagnosing bismuth toxicity. It is important for monitoring patients who may have been exposed to bismuth substances, as it provides a quantitative measure of bismuth levels in the blood.
Special Instructions
Patients should be advised to discontinue nutritional supplements, vitamins, minerals, and non-essential over-the-counter medications before the test, upon the advice of their physician, to avoid interference with test results. Collection should use tubes certified to be free of trace elements to prevent contamination of the sample.
Limitations
Elevated results may be due to skin- or collection-related contamination, including the use of tubes not certified to be trace element-free. If an elevated result is suspected to be due to contamination, confirmation with a second specimen collected in a certified trace element-free tube is recommended. The test development and performance characteristics were determined by ARUP Laboratories; not cleared or approved by FDA.
