Letter states reason for recall, health risk and action to take:\nPlease review this letter with your Medical Director to determine the appropriate\ncourse of action, including for any previously generated results, if applicable.\n\" Manually dilute patient samples that are > 18.00 mg/L:\n1. Navigate to the CH Test Definition screen.\n2. Under Measuring Interval, uncheck  Repeat when Outside Measuring Interval. \n3. For samples that generate test results > 18.00 mg/L, prepare a 1:2 manual\ndilution with saline solution (0.9% unbuffered Isotonic saline).\n4. From the Create Patient Order screen, order the sample and enter  2  in the\nmanual dilution field on the left of the screen.\nNote: The system will apply the 1:2 dilution factor and calculate the final result.\n5. Process the manually diluted sample.\n\n\"Complete and return the Field Correction Effectiveness Check Form attached to this letter within 30 days.\n\"Please retain this letter with your laboratory records and forward this letter to those who may have received this product.\nResolution\nThe Atellica CH B2M assay IFU will be updated with the above steps to support manual 1:2 dilution only with saline for samples > 18.00 mg/L.
