  2. Hemocytometer - Wikipedia

    en.wikipedia.org/wiki/Hemocytometer

    The proportion of the cells counted applies if not all inner squares within a set square are counted (i.e., if only 4 out of the 20 in a corner square are counted, then this term will equal 0.2). When counting large squares with a volume of 100 nanoliter (nL), a multiplication by 10000 leads to the desired cell count per milliliter.

  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. Cell counting - Wikipedia

    en.wikipedia.org/wiki/Cell_counting

    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.

  5. Colony-forming unit - Wikipedia

    en.wikipedia.org/wiki/Colony-forming_unit

    Theoretically, one viable cell can give rise to a colony through replication. However, solitary cells are the exception in nature, and in most cases the progenitor of a colony is a mass of cells deposited together. [1] [2] In addition, many bacteria grow in chains (e.g. Streptococcus) or clumps (e.g., Staphylococcus). Estimation of microbial ...

  6. 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).

  7. Virtual colony count - Wikipedia

    en.wikipedia.org/wiki/Virtual_colony_count

    This starting number of cells is equal to the number of surviving cells at the end of the two hour incubation with the antimicrobial agent. Because this procedure requires no actual colony formation or colony counting, it is termed "virtual colony count". Thus far the VCC technique has been limited to antimicrobial peptides.

    Counting cells is an important aspect of cytometry used widely in research and clinical medicine. It is generally achieved by using a manual or digital cytometer to count the number of cells present in small fractions of a sample, and then extrapolating to estimate the total number present in the entire sample. The resulting quantification is ...

  9. Breed method - Wikipedia

    en.wikipedia.org/wiki/Breed_method

    It is important first, to homogenize milk, heating it in a water bath at 40 °C for somatic cells that float to the surface along with the fat. The laboratory apparatus must be clean but not necessarily sterile, since the method is based on cell count and asepsis is not accurate. If later it is going to make detailed microbiological analyzes on ...
