Blood is counted using specialized computer technology during a test called a Complete Blood Count (CBC).
The Process of Counting Blood Cells
During a CBC, a sample of your blood is analyzed by a special computer. This computer performs the following tasks:
- Counts Red Blood Cells: Red blood cells, also known as erythrocytes, are counted. The computer also analyzes their size.
- Counts White Blood Cells: White blood cells, also called leukocytes, are also counted.
- Counts Platelets: Platelets, also known as thrombocytes, are counted as well.
CBC with Differential
If your healthcare provider orders a CBC with differential, the computer takes the process further:
- Counts Types of White Blood Cells: It identifies and counts the different types of white blood cells (neutrophils, lymphocytes, monocytes, eosinophils, and basophils).
- Counts Immature Cells: The computer also counts any immature cells that may be present in the sample.
This detailed analysis helps healthcare professionals to understand the overall health of your blood and helps in diagnosis of various conditions.
Key Takeaways
- A CBC is used to count the major types of cells in your blood: red blood cells, white blood cells, and platelets.
- A CBC with differential provides further detail by counting the different types of white blood cells.
- Specialized computers automatically count and assess blood cells during a CBC test.
