Evaluation of the Performance of the Sysmex XT-2000i Hematology Analyzer With Whole Blood Specimens Stored at Room Temperature

Characterization of pseudobasophilia on Sysmex-XT 1800i automated hematology analyser

“…The cell size, structure, or degree of granulation may change enough with time to make it no longer recognizable as a monocyte on automation. 12 However, in present study pseudomonocytosis was observed in 71 out of 207 cases (34.3%) on automation while none of the cases showed monocytosis on manual study. Pseudomonocytosis also presented with pseudobasophilia on automated analysis and was statistically significant in their co-existence (p<0.001).…”

Stability of athlete passport parameters during extended storage

“…With regard to selecting a reference range for reticulocytes, Banfi concluded that reference values were highly method dependent but included one Sysmex‐derived range (0.5–1.9%, n = 213) that was similar to the range reported recently by Hill et al . of 0.37–2.11% ( n = 56). Using the latter yields a 1/12th tolerance of 0.14%.…”

Determining the stability of complete blood count parameters in stored blood samples using the SYSMEX XE‐5000 automated haematology analyser

“…In contrast, the monocyte results show relative stability through the study period, when samples were stored at 4 °C, as indicated by the mean per cent change in the range of +5.645 to −0.536 in 24 h through 72 h. A study by Zini reported similar observations. It is difficult to determine the reason for changes, but it may possibly be attributed to the degree of granulation, cell structure or size of the monocyte which may change with time and make it difficult to count in the analyser . Gulati et al .…”
