FDA Determined
Cause 2		 Device Design
Action Alere sent an Updated Urgent Recall Notification Letter in March 2012 to all their customers who are in possession of one or more Cholestech LDX Systems. The updated letter provides the customers with important information about the problem identified and the actions to be taken. Customers are instructed to operate their device in a controlled environment that maintains humidity within 40-60% relative humidity if the device has not been upgraded with ROM pack v3.40. If humidity cannot be monitored, the device is no longer CLIA waived. Customers are instructed to complete the customer verification form. A previous notice from Alere sent in November 2010 instructs users to contact Alere to receive the ROM pack upgrade. Customers may email LDXROM@alere.com to request an electronic form to complete and return via email. Customers can expect their ROM packs approximately 10 to 14 business days after Alere receives their request. If customers have transferred ownership to another party, they can email Alere at LDXROM@alere.com with the updated contact information. If customers are not currently using their Cholestech LDX System, it is recommended that the ROM Pack upgrade be installed prior to restarting use of any Cholestech LDX analyzer. Customers with questions regarding this communication can call Alere at (877) 441-7440, option 1 or email at LDXROM@alere.com.
