The Agency understands this to be one of two fractions delivered. Additional data is forthcoming.</br>Reportedly, the underdose was due to a pinch clamp that was remaining on the infusion line during administration. It was noticed after the authorized user felt more pressure than normal when pushing the syringe, and stopped. The clamp was removed, and the authorized user completed the administration. No personnel or area contamination occurred.</br>The system was flushed five times to ensure no microspheres were caught in the tubing of the kit. Images of the waste container were taken immediately after the event, showing the remaining microspheres were contained in the inlet and outlet lines. Following the manufacturer's procedures, the license determined the patient only received 21.62 mCi of the intended 28.86 mCi.
