Absolute band count calculation is a laboratory technique used to determine the number of different types of white blood cells in a sample of blood. It is performed by staining the blood sample with a dye that binds to the DNA in the white blood cells, and then using a flow cytometer to count the number of cells that emit fluorescence at different wavelengths. This information can be used to diagnose and monitor a variety of conditions, including infections, leukemia, and lymphoma.
Absolute band count calculation is an important tool for diagnosing and monitoring a variety of conditions. It is a relatively simple and inexpensive test that can provide valuable information about the health of the immune system.
