If no eluate is obtained during generator elution, what should the technologist do next?

In the scenario where no eluate is obtained during a generator elution, the recommended step is to attempt elution again using another evacuated elution vial. This is a common troubleshooting step in nuclear medicine practice. Sometimes, the initial vial may not create an adequate vacuum or may contain an obstruction that prevents the proper passage of the saline or the desired radiopharmaceutical. By using a different evacuated vial, the technologist can rule out issues related to the elution container and may successfully obtain the eluate.

This approach allows for minimal disruption to the generator system while addressing the immediate issue of obtaining the eluate. It’s important to follow a systematic troubleshooting process that starts with simpler solutions before moving on to more invasive procedures. Attempting elution with another vial is efficient and often resolves the problem without the need for more complicated interventions like checking the tubing or disassembling the generator.
