Why is a differential white blood cell count helpful?
A WBC differential may be used to help diagnose the cause of a high or low white blood cell (WBC) count results seen on a CBC. It may also be used to help diagnose and/or monitor other diseases and conditions that affect one or more different types of WBCs.
What is the best count for white blood cells?
Normal Results The normal number of WBCs in the blood is 4,500 to 11,000 WBCs per microliter (4.5 to 11.0 × 109/L). Normal value ranges may vary slightly among different labs. Some labs use different measurements or may test different specimens. Talk to your provider about your test results.
What is the difference between a CBC and a CBC with differential?
A CBC test measures the total number of white cells in your blood. A test called a CBC with differential also measures the number of each type of these white blood cells.
Can a differential WBC count be used to distinguish T cells from B cells?
The total white cell count and differential is a vital investigation that will include total lymphocyte count and total neutrophil count but it cannot, for example, distinguish T lymphocytes from B lymphocytes.
Is it normal for white blood cells to fluctuate?
It’s important to note that white blood cell levels can fluctuate daily and even hourly, so it’s important not to jump to conclusions about your levels from a single blood test.
What is a normal CBC differential?
In general, the reference ranges are: White blood cells: 4,500 to 11,000 cells per microliter (cells/mcL) Red blood cells: 4.5 million to 5.9 million cells/mcL for men; 4.1 million to 5.1 million cells/mcL for women. Hemoglobin: 14 to 17.5 grams per deciliter (gm/dL) for men; 12.3 to 15.3 gm/dL for women.
What is included in WBC differential?
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.
How are white blood cells counted in a differential test?
The lab specialist then counts the number of each white blood cell type. The specialist may do a manual blood count, visually identifying the number and size of cells on the slide. Your specialist might also use an automated blood count. In this case, a machine analyzes your blood cells based on automated measurement techniques.
What are the white blood cells in the blood?
