Lead, RBC
Also known as: LEAD RBC
Use
The Lead, RBC test is performed to detect and measure the concentration of lead in red blood cells. This test is useful in assessing lead exposure in patients, particularly for monitoring lead levels in individuals who may have been exposed to lead in their environment or occupation. It is not recommended for routine assessment of lead toxicity but is crucial for determining lead burden in specific situations where blood lead levels need careful evaluation.
Special Instructions
The test requires submission of a Non-Permitted Laboratory Request Form to the NYDOH prior to specimen collection, as it is not approved in New York state. The test is performed by a non-ARUP laboratory, and separate specimens must be submitted if multiple tests are ordered.
Limitations
The test results may be affected by environmental contamination at the time of specimen collection. Unexpectedly elevated results should be verified by testing another specimen in a trace metal-free container. The test is not cleared or approved by the FDA, and its performance characteristics have been determined by NMS Labs. Specimens must be collected in certified metal-free containers to prevent contamination.
