The firm, Radiometer America, sent a "MEDICAL DEVICE FIELD CORRECTION" letter dated April 14, 2011, to all affected customers. The letter describes the product, problem and the actions to be taken. The letter provides the customers with a series of steps to be taken when replacing the Calcium Membrane (Until further notice the above procedure must be carried out when replacing the Calcium membrane). The letter also provides quality control instructions for verifying calcium performance. Additionally, the customer is required to manually adjust the upper and lower QC limits on the analyzer in relation to the limits printed on the insert sheet in order to detect the bias during quality control measurements (This must be done for every lot of QC ampoules used, and for any new lot of ampoules installed). The letter asks that each customer complete and return the attached form via fax to 440-871-0463, in order to verify that the notification letter was received.
