Sysmex America

Sysmex was made aware of a report of false results due to carry-over caused by the sporadic omission of the probe wash step during antibody pipetting on the PS-10 Sample Preparation System.

Insufficient amount of antibody without an error message or alarm

When excessive amounts of urine spills on the rack transport track and reaches the electrical components of the CV-11 conveyor, there is a potential for smoke and/or sparks which may present a combustion hazard.

Software mismatch-When the software versions between the SP-50 and CF-70 are not matched, and an error condition occurs requiring the operator to open the cover door of the CF-70 to remove slides or slide magazines from the CF-70, the operation of the CF-70 does not halt.

The fluorescent platelet counts (PLT-F) and immature platelet fraction (IPF) values can be falsely low when using affected lots of Fluorocell PLT.

There is potential that fluorescent platelet (PLT-F) and immature platelet fraction (IPF%, #) results obtained using the lots listed above may exhibit lower than actual PLT-F and IPF values. The issue may be recognized by a large discrepancy between the impedance platelet (PLT-I) result and the PLT-F result. In most cases, the falsely decreased PLT-F results display a PLT Abn Scattergram message with an asterisk beside the result or an Action Message: Difference between PLT and PLT- F. Check the results. These are indicators of unreliable data. In rare instances, platelet flags may be absent. The PLT-I results are unaffected.

Reported customer complaints of automated hematology analyzers catching fire due to misalignment of an internal protective sheet that shields electronic components from salty reagents. Build-up of salt deposits on unprotected electronic components may combust due to heat generated by electronics when instrument cycles. Completed CAPA identified the root cause as supplier providing defective component (sensor ready valve) and the misalignment of the electronic protective shield during manufacturing of the device.

There is a potential that fluorescent platelet (PLT-F) and immature platelet fraction (IPF%) results performed using the recalled lots may exhibit lower than expected PLT-F and IPF values. The issue may be recognized by a large discrepancy between the Impedance platelet (PLT-I) value and a false low PLT-F value. In most cases, the falsely decreased PLT-F results displayed a "PLT Abn Scattergram" message with asterisks beside the results indicating the data is unreliable. In rare instances, platelet flags may be absent. The PLT-I counts are unaffected. The PLT-F is a reflex test used to confirm PLT-I results due to flagging or low values. As such, the likely impact to patient results is low. Affected results display a discrepancy between the PLT-I and PLT-F, with lower than expected PLT-F results that do not match the patient's clinical picture.

The current Century Break patch did not contain the same setting for the Century Break year for both the Red Hat Linux and GUI files. Due to the mismatch in file settings, the software could not properly calculate a purge date for the database files based on the customer data retention setting in the application. This resulted in the database files meeting its maximum capacity and causing system p

The data printed on the thermal printer may omit a digit or decimal point in the results or sample identification number.

There is a variation of reticulocyte counts between XE Series (XE-2100, XE-5000) and XT-Series (XT-2000i, XT-4000i) hematology analyzers that may result in a retic counts that are an average of 21% lower on the XE-Series because of a low bias.
