A white blood cell differential is a medical laboratory test that provides information about the types and amounts of white blood cells in a person's blood. The test, which is usually ordered as part of a complete blood count (CBC), measures the amounts of the five normal white blood cell types – neutrophils, lymphocytes, monocytes, eosinophils and basophils – as well as abnormal cell ...
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).
Monocyte distribution width (MDW) is a cytometry-based parameter that measures the range of variation of monocytes.If the parameter is available, it is reported as part of the standard complete blood count (CBC) with differential.
The red blood cell indices, which indicate the average size and hemoglobin content of red blood cells, are also reported, and a white blood cell differential, which counts the different types of white blood cells, may be included. The CBC is often carried out as part of a medical assessment and can be used to monitor health or diagnose diseases.
For example, the complete blood count can help a physician to determine why a patient feels unwell and what to do to help. Cell counts within liquid media (such as blood , plasma , lymph , or laboratory rinsate ) are usually expressed as a number of cells per unit of volume , thus expressing a concentration (for example, 5,000 cells per ...
The ANC is almost always a part of a larger blood panel called the complete blood count. The ANC is calculated from measurements of the total number of white blood cells (WBC), usually based on the combined percentage of mature neutrophils (sometimes called "segs", or segmented cells) and bands, which are immature neutrophils.
measure of the range of variation of red blood cell volume that is reported as part of a standard complete blood count. Red blood cell distribution width ( RDW ), as well as various types thereof ( RDW-CV or RCDW and RDW-SD ), is a measure of the range of variation of red blood cell (RBC) volume that is reported as part of a standard complete ...
The number of leukocytes in the blood is often an indicator of disease, and thus the white blood cell count is an important subset of the complete blood count. The normal white cell count is usually between 4 × 10 9 /L and 1.1 × 10 10 /L. In the US, this is usually expressed as 4,000 to 11,000 white blood cells per microliter of blood. [7]
