What is automated differential in blood test?
Automated differential blood count: Automated hematology instruments using multiple parameters and methods (such as fluorescence flow cytometry and impedance) are used to count and identify the 5 major white blood cell types in blood (so-called 5-part differential count): neutrophils, lymphocytes, monocytes, ...
What is flow cytometry in hematology?
Flow cytometry is a laser-based technique used to detect and analyze the chemical and physical characteristics of cells or particles. It is most commonly used to evaluate bone marrow, peripheral blood and other fluids in your body.
What are the different types of WBC?
White blood cells are part of the body's immune system. They help the body fight infection and other diseases. Types of white blood cells are granulocytes (neutrophils, eosinophils, and basophils), monocytes, and lymphocytes (T cells and B cells).
What is the principle of cell counter?
The traditional method for counting cells is electrical impedance, also known as the Coulter Principle. Whole blood is passed between two electrodes through an aperture so narrow that only one cell can pass through at a time. The impedance changes as a cell passes through.
