Action

Sysmex Corporation sent a Product Notification Field Correction letter were to all affected customers of record. The letters included instructions for customers to: 1) Review results with an unexpected increase in Hgb, MCH, MCHC, and/or PLT-I. The increase may result in a low or normal value being artificially elevated to either a normal result or a result above the reference ranges, or a high value being artificially increased. There is negligble impact to the RBC when the issue occurs; 2) The relationship with an elevated Hgb would cause the indices (MCH and MCHC) values to appear to be abnormally elevated and may result in the results being flagged for verification or indicated to be outside of reference ranges; 3) Review any "Turbidity/Hgb Interf?" flag which will automatically trigger at an MCHC of 37.5 g/dL; 4) If Hgb is affected, the PLT-I may be also. Review any PLT-I result when an unexpected increase in MCH/MCHC or "Turbidity/Hgb Interf?" flag occurs; 5) Gross interference is likely to trigger a flag, however there is a potential any interference could increase the Hgb or the PLT-I count from a lower level to an "normal" level. Follow laboratory protocol for confirming unexpected results. Customers were further advised that they will be contacted by a Sysmex Field Representative within 180 days to schedule an appointment to replace the rinse cup on the analyzer(s) and that version 00-16 software will be installed to change the rinsing sequence for the aspiration probe. Customers with questions are requested to e-mail the Sysmex Technical Assistance Center. Urgent questions can be answered by calling the Technical Assistance Center at 888-879-7639 (24 hours a day / 7 days a week).
