Enter the total White Blood Cell count and the percentage of lymphocytes into the calculator to determine the Absolute Lymphocyte Count. This calculator can also evaluate any of the variables given the others are known.
Absolute Lymphocyte Count Formula
The following formula is used to calculate the Absolute Lymphocyte Count (ALC).
ALC = WBC * (Lymphocytes / 100)
Variables:
- ALC is the Absolute Lymphocyte Count (cells/µL)
- WBC is the total White Blood Cell count (cells/µL)
- Lymphocytes is the percentage of lymphocytes in the total WBC count
To calculate the Absolute Lymphocyte Count, multiply the total White Blood Cell count by the percentage of lymphocytes in the total WBC count, then divide the result by 100.
What is an Absolute Lymphocyte Count?
An Absolute Lymphocyte Count (ALC) is a blood test that measures the number of lymphocytes in a person’s blood. Lymphocytes are a type of white blood cell that plays a crucial role in the immune system by fighting off infections and diseases. An ALC is often used to monitor the immune system, particularly in individuals with certain types of cancers, HIV, or who have had an organ transplant. It can help doctors determine the severity of an illness, monitor the body’s response to treatments, and predict a patient’s likelihood of recovery.
How to Calculate Absolute Lymphocyte Count?
The following steps outline how to calculate the Absolute Lymphocyte Count (ALC).
- First, determine the total White Blood Cell count (WBC) in cells/µL.
- Next, determine the percentage of lymphocytes (% Lymphocytes) in the total WBC count.
- Next, gather the formula from above = ALC = WBC * (% Lymphocytes / 100).
- Finally, calculate the Absolute Lymphocyte Count (ALC) in cells/µL.
- After inserting the variables and calculating the result, check your answer with the calculator above.
Example Problem:
Use the following variables as an example problem to test your knowledge.
total White Blood Cell count (WBC) = 8000 cells/µL
percentage of lymphocytes (% Lymphocytes) = 30%
