What we see as the essence: The GFHC reviewed in detail the criteria used within the CBC to generate blood smears and has decided on a number of minimum recommendations, defining threshold values and various situations in which the blood smear review is desirable.

Wang H et al. (2013): Use of RBC-O and S-MCV Parameters of Sysmex XE-2100 in a Patient with RBC Cold Agglutination Clin Lab.;59: 217
What we see as the essence: A combination of sample dilution and the use of RBC parameters from the RET channel on the XE-2100 is described to obtain accurate RBC parameters from samples with RBC cold agglutination without heating of the sample.

Godon A et al. (2012): Anomalies et erreurs de détermination de l’hémogramme avec les automates d’hématologie cellulaire Partie 3. Hémoglobine, hématies, indices érythrocytaires, réticulocytes*. Ann Biol Clin 2012; 70(2): 155 Article in French - Free online.
What we see as the essence: A summary report about potential interferences of CBC parameters with focus on situations leading to abnormal HGB, RBC and MCV, resulting in abnormal calculated RBC indices, e.g. MCHC. Alternative strategies may support management of interferences.

ESR

Kratz A et al. (2017) ICSH recommendations for modified and alternate methods measuring the erythrocyte sedimentation rate. Int J Lab Hematol; 39(5):448.
What we see as the essence: The gold standard for the determination of the erythrocyte sedimentation rate is still the Westergren method. Alternative methods should be accepted when they have been appropriately validated and their results are expressed by comparison with the gold standard.

Schapkaitz E et al. (2017): Evaluation of the InteRRliner automated erythrocyte sedimentation rate analyzer for a large academic laboratory. Int J Lab Hematol; 39(3):e66-e69.
What we see as the essence: Indicated by the high correlation coefficient of 0.96 the InteRRliner showed an excellent comparability to the HumaSed ESR method.

Malaria-infected RBC (MI-RBC)

Post A et al. (2019) The XN-30 hematology analyzer for rapid sensitive detection of malaria: a diagnostic accuracy study; BMC Medicine; 17(1):103; Free online
What we see as the essence: The novel technology of the Sysmex XN-30 provides a robust, rapid, automated and objective platform for diagnosing and quantifying malaria. The XN-30 ensures the prompt initiation of the malaria treatment and the malaria anaemia together with the reliable treatment monitoring.

Pillay E et al. (2019) Evaluation of automated malaria diagnosis using the Sysmex XN-30 analyser in a clinical setting; Malaria J 18(1) : 15; Free online
What we see as the essence: The novel technology of the Sysmex XN-30 provides a robust, rapid, automated and accurate platform for diagnosing malaria. It allows precise recognition and demonstrated a sensitivity and specificity of 100% for malaria parasitaemia detection.
