    Cell counting is any of various methods for the counting or similar quantification of cells in the life sciences, including medical diagnosis and treatment. It is an important subset of cytometry , with applications in research and clinical practice.

  3. Cytometry - Wikipedia

    en.wikipedia.org/wiki/Cytometry

    Cytometers are the instruments which count the blood cells in the common blood test.. Cytometry is the measurement of number and characteristics of cells.Variables that can be measured by cytometric methods include cell size, cell count, cell morphology (shape and structure), cell cycle phase, DNA content, and the existence or absence of specific proteins on the cell surface or in the ...

  4. Complete blood count - Wikipedia

    en.wikipedia.org/wiki/Complete_blood_count

    A complete blood count (CBC), also known as a full blood count (FBC), is a set of medical laboratory tests that provide information about the cells in a person's blood.The CBC indicates the counts of white blood cells, red blood cells and platelets, the concentration of hemoglobin, and the hematocrit (the volume percentage of red blood cells).

  5. Flow cytometry - Wikipedia

    en.wikipedia.org/wiki/Flow_cytometry

    Cells are often labeled with fluorescent markers so light is absorbed and then emitted in a band of wavelengths. Tens of thousands of cells can be quickly examined and the data gathered are processed by a computer. [5] Flow cytometry is routinely used in basic research, clinical practice, and clinical trials. Uses for flow cytometry include:

  6. Celloscope automated cell counter - Wikipedia

    en.wikipedia.org/wiki/Celloscope_automated_cell...

    Celloscope automated cell counter was developed in the 1950s for enumeration of erythrocytes, leukocytes, and thrombocytes in blood samples. [1] Together with the Coulter counter, the Celloscope analyzer can be considered one of the predecessors of today's automated hematology analyzers, as the principle of the electrical impedance method is still utilized in cell counters installed in ...

  9. Viable count - Wikipedia

    en.wikipedia.org/wiki/Viable_count

    A dilution of the cells to be counted is prepared and mixed with Trypan blue, this is normally the stain of choice because it is taken up by dead cells and actively excluded from live cells. Once the cells have been stained, they are counted using a hemocytometer, then a calculation is carried out to the original concentration of live cells. [1]
