White Blood Cell Count and Differential Count
Emergency Medicine Clinics of North America, 1986Current methods for performing the white blood cell count and differential count along with recent technologic advances are discussed. Sources of error and variation in these tests are presented. The use of the white blood cell count and the differential count in a variety clinical situations is reviewed.

Microsystems for Blood Cell Counting
Advances in Science and Technology, 2008This paper presents two biomedical microsystems for blood cell counting, designed and built through MultiMEMS Multi-Project Wafer (MPW) service and the microBUILDER European project. Dies mm in size, made of a micromachined glass-silicon-glass triple stack, host two new kinds of multiple micro-counters, suitable to investigate the feasibility of blood ...

Interrelationship between platelet count, red cell count, white cell count and weight in men
Clinical & Laboratory Haematology, 2008In 83 healthy normotensive males aged 20-55 years the platelet count is positively correlated with the red cell count (r = 0.371; P = 0.0006), the white cell count (r = 0.358; P = 0.0009), and with weight (r = 0.252; P = 0.0269). The red cell count is also positively related with the white cell count (r = 0.242; P = 0.0278) and with weight (r = 0.326 ...

Counting stem cells: methodological constraints
Nature Methods, 2012The number of stem cells contributing to hematopoiesis has been a matter of debate. Many studies use retroviral tagging of stem cells to measure clonal contribution. Here we argue that methodological factors can impact such clonal analyses. Whereas early studies had low resolution, leading to underestimation, recent methods may result in an ...

Addis1,2established the fact 30 years ago, with use of a counting chamber, that both white and red cells normally occur in urine. He found top values of 2,000,000 white cells and 400,000 red cells in the 12-hour night urine specimens of 74 apparently healthy medical students.

Science, 1996
The rules by which the T cells of the immune system are activated by foreign peptides have seemed inconsistent and counterintuitive. In this week's issue, Viola et al . ( p. 104 ) report that the T cells actually count how many T cell receptors are engaged.

Acta Medica Scandinavica, 1968
Abstract Counting of blood cells in urine is most accurately performed by means of a haemocytometer. The errors of the method are related to technique, observer inaccuracy and uneven distribution of cells in the haemocytometer.Leucocytes and non‐squamous epithelial cells in urine, when present in small numbers, have been shown to be distributed in the ...

Automated counting of T cell rosettes
Journal of Immunological Methods, 1976Human T cell rosettes were enumerated using an automated particle counter, the Bio/Physics Cytograf 6300A. An electronic oscilloscope representation of particle absorbance and scatter of a focused laser beam allows the separation and enumeration of both rosetted and non-rosetted lymphocytes.

Automatic cell counting with ImageJ
Analytical Biochemistry, 2015Cell counting is an important routine procedure. However, to date there is no comprehensive, easy to use, and inexpensive solution for routine cell counting, and this procedure usually needs to be performed manually. Here, we report a complete solution for automatic cell counting in which a conventional light microscope is equipped with a web camera to
