What should be done if an eluate sample shows significantly high aluminum levels multiple times?

When an eluate sample shows significantly high aluminum levels on multiple occasions, the most prudent action is to dispose of the eluate and contact the manufacturer. High aluminum levels can pose a risk to patient safety, especially in radiopharmaceuticals intended for injection or ingestion. Aluminum contamination may interfere with the efficacy of the radiopharmaceuticals and could potentially lead to adverse health effects. Proper procedure in such situations is to ensure that contaminated eluates are not used in any capacity. Additionally, contacting the manufacturer allows for an investigation into the possible sources of contamination and guidance on next steps to ensure that future batches are safe for use. This response highlights a commitment to patient safety and adherence to quality control standards in radiopharmacy.
