Problem Or Issue:
Abbott has confirmed that a performance shift in the ARCHITECT Intact Parathyroid (PTH) assay has the potential to generate falsely elevated results on patient samples. 

This issue affects ARCHITECT Intact PTH Assay List Number 8K25, Reagents (8K25-20, 8K25-25, 8K25-27*), Calibrators (8K25-01) and Controls (8K25-10). Refer to attached Field Safety Notice (FSN). 

The scope of the issue affects devices manufactured between May 2012 and November 2013. 

*Note: This list number is not CE-marked and is distributed to USA and Puerto Rico only. 

Background Information Or Related Documents:
Results generated with impacted lots may demonstrate a positive shift relative to those generated with previous reagent and/or calibrator lots. The issue may also impact your established ARCHITECT Intact PTH reference ranges. Abbott ARCHITECT Intact PTH Controls do not detect the shift. All current reagent, calibrator and control inventory is impacted. 

In a study completed in January 2014, using current in-date reagent and calibrator lots, patient results demonstrated a magnitude of shift averaging approximately 13% to 45% when compared to a study completed in August 2012. The shift was observed across the full analytical range of the assay.

Actions To Be Taken:
Abbott has launched a product recall for affected lots of ARCHITECT Intact PTH assay reagents, calibrators and controls and has issued a FSN to provide instructions on what actions your laboratory must take (as follows): 

- Immediately discontinue use of, and destroy, any remaining inventory of ARCHITECT Intact PTH assay according to your laboratory procedures. 
- To continue Intact PTH testing at your laboratory, Abbott recommends that you identify an alternate method for testing patient samples. If further guidance is needed, please contact your Abbott sales representative. 
- This letter should be reviewed with the treating physician or healthcare provider to ensure they are aware of the issue and can determine whether re-evaluation of the patient is necessary. 
- If you have forwarded any product to other laboratories, please inform them of this FSN. 

The IMB recommends that results with the ARCHITECT Intact PTH assay are reviewed as appropriate to determine whether re-evaluation of the patient is necessary. 

Please forward this safety notice to all those who need to be aware of this action within your organisation and to maintain awareness over this safety notice for an appropriate time period.
