Page 1 of 8 Processing UK NEQAS Differential and Reticulocyte Specimens on Sysmex Analysers Please follow the instructions from NEQAS regarding specimen handling very carefully for each survey. Only process the survey through the mode requested by UK NEQAS. Full Blood Count surveys should be processed for CBC or CBC/DIFF only profiles. Do not perform any additional profiles as this may cause different parameters to be reported. Do not perform FBC survey through QC Mode. In order to obtain the correct results, the UK NEQAS Automated Differential Leucocyte Count (ADLC) and sometimes Reticulocyte Count surveys have to be processed using the QC mode analysis profile on Sysmex haematology analysers. Only UK NEQAS ADLC samples with the correct matrix letter of J are for Sysmex analysers. Please see instructions below on how to process the UK NEQAS samples. XN Series 1.
