Sysmex Fluorocell(R) PLT Fluorocell PLT is used to stain platelets in a diluted blood sample for the counting of platelets with the Sysmex XN-Series automated hematology analyzers

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.
