A 66-year-old woman, recently diagnosed with T cell prolymphocytic leukaemia (PLL) was admitted for cytotoxic therapy, with a potassium (K) of 5.5 mmol/L on admission as measured on a lithium heparin plasma sample (Beckman DxC800; Beckman Coulter Diagnostics, Fullerton, CA, USA). The sample was analysed within 70 min of collection. The white blood cell count (WBC) was 460=10/L (Sysmex XE5000; S...

OBJECTIVE Urinary tract infections (UTIs) are a common problem in the elderly population. Urine culture is still considered the "gold standard" to diagnose infection in this population. However, urine cultures are laborious and costly, and most samples will yield no growth. METHODS An evaluation was made of the Sysmex UF-1000i flow cytometer as a screening tool for UTI in an elderly populatio...

The aim of this study was to establish reference intervals (RIs) for the hemogram and iron status biomarkers in a physically active population. The study population included male volunteers (n = 150) with an average age of 19 ± 1 years who had participated in a regular and controlled exercise program for four months. Blood samples were collected to determine hematological parameters using a Sys...

OBJECTIVES To evaluate the performance of automated leucocyte (white blood cell; WBC) counting by comparison with manual counting. METHODS The number of WBC was determined in heparinized synovial fluid samples by the use of (i) a standard urine cytometer (Kova) and a microscope (reference method) and (ii) a haematology analyser (Sysmex XE-2100; WBC/BASO and DIFF channels). Imprecision within ...

Diverse approaches have been used to assure the analytical quality of automated hematology; as such, there is great variation in their error detection capabilities. We summarize the intralaboratory performance of a cohort of Sysmex XE-2100's running e-Check hematology quality control (QC). The imprecisions of a median performing (50th percentile imprecision) and more imprecise [15th percentile ...

The bone marrow aspiration test conventionally has been performed by visual methods, using a light microscope, because automatic blood cell analyzers cannot adequately capture erythroblasts and immature granulocytes (IGs) (Tatsumi et al.: Osaka City Med J 1988;34:135-146; Tatsumi et al.: Am J Clin Pathol 1986;86:50-54). With the development of the XE-2100 automatic blood cell analyzer (Sysmex C...

OBJECTIVES The Sysmex XE-5000 instruments (Sysmex, Kobe, Japan) count immature granulocytes (IGs) and use the "Imm Gran?" flag to signal unreliable results. This study investigated the usefulness of the "Imm Gran?" flag and the analytical and diagnostic performance of the IG measurements in a side-by-side evaluation. METHODS In total, 408 samples were analyzed on three XE-5000 instruments. Th...
