The recalling firm issued letters dated 1/10/2022 to the main office locations of the end-user facilities explaining the reason for recall, hazard involved, and requesting they discontinue use per their instruction on 11/30/2021. (The main office locations were only instructed to discontinue use at that time and the product was not under recall then.) The letter requested return of the kits as soon as possible and the firm's Client Success team will contact the end-user facilities to provide detailed instructions to complete and return. An Acknowledgement and Receipt Form was enclosed for completion and return via email to the firm. The Client Success Team began sending follow-up emails to the end-user facilities on 1/11/2022 which provided the number of kits the firm should have and that they should be returned by 1/21/2022. Attached was a return shipping label and a guide with additional details on how to return the kits. The follow-up email also contained the reason for recall and hazard involved. The home office for the end-user facilities sent out emails beginning 1/11/2022 to their end-user facilities containing the subject line "COVID-19 UPDATE: Base10 Test Kit Recall Instructions." The email contained an advisory which said facilities should not be discarding old Base10 test kits that were discontinued for use. It also said that Base 10 will be performing a recall on all RBC Kits beginning today and the end user will receive formal notification from Base 10 as well. Return instructions were sent with the email.
