Asserachrom® HPIA

After receiving three customer complaints (from outside Canada and the US), Stago investigated and confirmed that approximately 5% of reagent 1 strips had a defect for Asserachrom® HPIA  lot 271288.  When the defect is present, every well in the impacted strip produces negative results.  Kit reference reagent 6 and control 2 (reagent 7b) produce low optical density (OD) readings, similar to those of control 1 (reagent 7a).  As a result, these values will not meet the requirements specified in the assigned value sheet for the lot and must not be used. 
consignee actions:

• Stop using lot 271288 and dispose of all remaining product according to local regulations. 
• Complete, sign, and return acknowledgement form.
