Nuclear medicine vials supply update

24 September 2022

The saline vials that ANSTO provides with the Gentech and Technelite generators and evacuated vials provided with Gentech generators have now passed ANSTO’s quality assurance testing.

After consultation with the supplier and the TGA, ANSTO is advising customers that the quarantine notice previously issued on 21 September 2022 is being withdrawn, and hence customers are permitted to resume the normal intended use of these vials.

ANSTO and its supplier’s investigation and risk assessment have determined the product is safe for patient use.

Why is the product being released?

  • Significant testing of the vials to ascertain the likely cause of the residue within the vials has been undertaken. The findings are that the substance identified in the glassware is a silicon compound.  
  • ANSTO has reviewed the possible impact to patient safety, and concluded any residual risk is low.
  • The supplier has advised it is lifting the quarantine of their own stock and will resume normal operations.

When will customers next receive saline vials?

  • Customers who did not receive saline vials last week will receive them on Tuesday 27 September.  
  • Normal vial deliveries will resume from Tuesday 27 September.

23 September 2022

ANSTO continues to work constructively with the TGA and the supplier. We are working through our analysis and will be able to provide customers with an update on the evening of 24 September.

21 September 2022

ANSTO’s supplier of the glass vials used in several nuclear medicine products has advised us of a quality issue. The quality issue is an unexpected residue of unknown origin found inside the glass vials. The issue is limited to vials only.

Currently, ANSTO is only aware of the issue affecting vials provided as part of our Tc-99m generators.

At this stage, the impact, if any, of the residue on patient safety has not been fully determined.

ANSTO is directing customers to not use the saline vials provided with the Gentech and Technelite  Tc-99m generators and the evacuated Gentech vials until the impacted products have been assessed. The Technelite evacuated vials are not impacted and can be used.

This advice is based on ANSTO’s risk assessment and commitment to patient safety and meeting the highest possible quality assurance standards and applies to the above batch numbers.
Next steps 

ANSTO is working cooperatively with the supplier and the TGA and is undertaking analysis to quantify any risk to patient safety so we can advise customers of the action required. This could mean a return to business or recall of the vials depending on the results of the investigation.

ANSTO will provide an update by Friday 23 September.
