Here are the steps to use the Absolute Lymphocyte Count Calculator:
That's it! The Absolute Lymphocyte Count Calculator is a quick and easy tool to use.
The formula for calculating the absolute lymphocyte count (ALC) is as follows:
ALC = WBC count x (% lymphocytes/100)
where:
For example, if a person has a WBC count of 8,000 cells/μL and a percentage of lymphocytes of 25%, the calculation would be:
ALC = 8,000 x (25/100) ALC = 2,000 cells/μL
So, the absolute lymphocyte count, in this case, would be 2,000 cells/μL.
Here's a chart that can help you interpret the results of the Absolute Lymphocyte Count Calculator:
| ALC Value (cells/μL) | Interpretation |
|---|---|
| < 1000 | Severe lymphocytopenia (low lymphocyte count) |
| 1000 - 1500 | Mild to moderate lymphocytopenia |
| 1500 - 4000 | Normal range |
| > 4000 | Mild to moderate lymphocytosis (high lymphocyte count) |
It's important to keep in mind that the interpretation of the ALC results may depend on the individual's health status, age, and other factors. Therefore, it's always best to consult with a healthcare provider for a proper diagnosis and treatment plan.
The following table summarises the five types of WBCs and their involvement in immune function:
| WBC | Shift pattern |
| Neutrophils | Increased in bacterial infections or inflammatory disease |
| Decreased in severe infections, liver or spleen diseases | |
| Lymphocytes | Increased in bacterial, viral infections, leukaemia, spleen conditions, lupus or HIV infections |
| Monocytes | Increased in some leukaemias |
| Decreased in bone marrow injury | |
| Eosinophils | Increased allergic reactions, skin inflammation or parasitic infections |
| Basophils | Increased in leukaemia, radiation therapy or long-term inflammation |
White blood cell differential count is one of the blood tests used in the diagnosis of conditions that affect the immune system:
Here is a table that shows the normal range of absolute lymphocyte count (ALC) based on age:
| Age Range | Normal Range for ALC |
|---|---|
| Newborns | 2500 - 8000 cells/μL |
| Infants (1-5 months) | 4000 - 10000 cells/μL |
| Children (6 months to 2 years) | 2500 - 7500 cells/μL |
| Children (2-6 years) | 1500 - 7500 cells/μL |
| Children (6-12 years) | 1500 - 6000 cells/μL |
| Adults (>12 years) | 1000 - 4000 cells/μL |
Here is a table that shows the normal range for ALC in different measurement units:
| Measurement unit | Normal range for ALC |
|---|---|
| cells/μL | 1000 - 4000 |
| cells/L | 1.0 - 4.0 |
| 10^9 cells/L | 1.0 - 4.0 |
Again, it's important to keep in mind that the interpretation of the ALC results may depend on the individual's health status, age, and other factors. Therefore, it's always best to consult with a healthcare provider for a proper diagnosis and treatment plan.
The Absolute Lymphocyte Count (ALC) Calculator offers several benefits, including:

Reference
To calculate the absolute lymphocyte count (ALC), you need to know two things: the total white blood cell count (WBC) and the percentage of lymphocytes in the differential white blood cell count.
The formula for calculating ALC is:
ALC = WBC count × % lymphocytes/100
For example, if the WBC count is 8000 cells/μL and the percentage of lymphocytes in the differential count is 20%, then the ALC would be:
ALC = 8000 × 20/100 ALC = 1600 cells/μL
Therefore, the absolute lymphocyte count in this example is 1600 cells/μL.
It's important to note that the ALC can vary based on various factors such as age, underlying health conditions, and medication use. A healthcare provider should always interpret the ALC results in the context of the individual's overall health status.
If lymphocytes are high, it is called lymphocytosis. There are many possible reasons why lymphocytes may be high, including:
Infections: A common cause of lymphocytosis is viral infections such as infectious mononucleosis, cytomegalovirus, and hepatitis.
Chronic lymphocytic leukemia: This is a type of cancer that affects the lymphocytes, causing an overproduction of abnormal lymphocytes.
Autoimmune disorders: Some autoimmune disorders, such as lupus and rheumatoid arthritis, can cause an increase in lymphocytes.
Medications: Certain medications, such as steroids, can cause an increase in lymphocytes.
Stress: Emotional or physical stress can cause an increase in lymphocytes.
Other conditions: Other conditions such as tuberculosis, lymphoma, and HIV infection can cause an increase in lymphocytes.
It's important to note that lymphocytosis is not always a cause for concern and maybe a normal response to certain situations such as an infection. However, in some cases, lymphocytosis can indicate a more serious underlying condition. Therefore, it's always best to consult with a healthcare provider for a proper diagnosis and treatment plan.
If the absolute lymphocyte count (ALC) is low, it is called lymphocytopenia. There are many possible reasons why ALC may be low, including:
Infections: Certain viral infections such as HIV and hepatitis, as well as bacterial and fungal infections, can cause a decrease in lymphocytes.
Medications: Certain medications such as chemotherapy drugs and immunosuppressive medications can cause a decrease in lymphocytes.
Autoimmune disorders: Some autoimmune disorders, such as lupus and rheumatoid arthritis, can cause a decrease in lymphocytes.
Bone marrow disorders: Bone marrow disorders such as aplastic anemia, myelodysplastic syndrome, and leukemia can cause a decrease in lymphocytes.
Radiation therapy: Radiation therapy can cause a decrease in lymphocytes.
Other conditions: Other conditions such as malnutrition, alcoholism, and stress can cause a decrease in lymphocytes.
Lymphocytopenia can increase the risk of infections and other health complications. However, the severity of the effects of lymphocytopenia may depend on the underlying cause and the individual's health status. Therefore, it's always best to consult with a healthcare provider for a proper diagnosis and treatment plan.
