Action Urgent Medical Device Recall letters, dated July 30, 2018, were sent via email and postal mail on August 1, 2018 (for those customers not on their email notification system). On 05/22/19, second Urgent Medical Device (UMDC) Recall letters, and Important Safety Information notices, dated May 20, 2019 (replacing BEC UMDC letter dated July 30, 2018), were sent via mail and/or phone and/or e-mail informing customers perform the following actions: - Run samples on an instrument not subject to this recall to confirm the platelet results. - If an alternative instrument is not available, use the following quality control measures to aid in identification of discrepant platelet results: a) Perform manual scanning/estimate of platelets on a peripheral smear and compare with instrument results. Note that this method will identify samples with marked to moderate thrombocytopenia but may not identify smaller discrepancies. b) Repeat testing of samples in a workflow configuration may facilitate the identification of discrepancies. If an erroneous result is detected, review results from adjacent samples, i.e., those tested on the instrument both before and after the erroneous result. c) Additional instrument and/or LIS features including reference ranges, XM (exponentially-weighted moving average) and delta checks may be informative. d) Follow your laboratory's standard operating procedure to confirm unexpected results. - Ongoing investigation indicates that the probable root cause is the sweep flow disruption that may occur following the "Clear RBC Apertures" procedure. This potential root cause is currently under further investigation. Customers should discontinue using this procedure. If you suspect that your instrument has a clogged aperture that will not clear, discontinue use of the analyzer, contact Customer Support Center and request service. - Communicate to the ordering physicians the need to avoid patient treatment based solely on any single test resu
