Current Protocols in Cytometry, 1997
AbstractThis unit presents protocols for counting cells using either a hemacytometer or electronically using a Coulter counter. Cell counting with a hemacytometer permits effective discrimination of live from dead cells using trypan blue exclusion. In addition, the procedure is less subject to errors arising from cell clumping or size heterogeneity ...

Platelet Count Is Positively Correlated with White Cell Count and Red Cell Count
Haemostasis, 2009Platelet count is positively correlated with the white cell count in healthy males aged 20–68 years (p < 0.002) and in healthy medical students of both sexes aged 18–22 years (p < 0.0001). Platelet count is also positively correlated with red cell count in healthy males (p < 0.02).

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.

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.

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 ...

Pediatrics, 1986
I read with interest the article by Portnoy and Olson on normal cerebrospinal fluid cell (CSF) counts. However, I believe there are a number of problems in accepting that the information presented lives up to the title. First, they fail to state what their criteria were for confidently excluding central nervous system (CNS) infection.

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 ...

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 ...

Practical Cell Counting Method Selection to Increase the Quality of Cell Counting Results
The Journal of Immunology, 2021Abstract The importance of cell counting has increased significantly in the last decade due to the major advances in the fields of cell and gene therapy, biologics production, and regenerative medicine. This has necessitated the development of a standardized approach to cell counting assays. In the recent years, the U.S.

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 ...
