What should a technologist do if they visually inspect a unit dose of P32 chromic phosphate and note it is a blue green color?

In the context of handling radiopharmaceuticals, it is crucial for technologists to ensure that the products they are working with meet specific quality and safety standards. If a unit dose of P32 chromic phosphate is observed to be an unusual color, such as blue-green, this indicates a potential issue with the integrity or composition of the radiopharmaceutical.

The blue-green color is not characteristic of a properly prepared dose of P32 chromic phosphate. This abnormal coloration could suggest contamination, degradation, or improper formulation, which could affect the safety and efficacy of the treatment. Therefore, withdrawing the unit dose is the appropriate action to ensure patient safety, as administering a potentially compromised dose could lead to ineffective treatment or unwanted side effects.

In contrast, contacting the manufacturer might provide helpful information, but it does not immediately address the potential risk to patient safety. Rescheduling the procedure does not resolve the issue with the dose, nor does placing it in radioactive waste, which simply disposes of the problematic dose without ensuring that no harm comes to the patient from using an altered product.
