The accomplished team of calculator-online brings another health tool known as ‘alc calculator.’ The tool works as natural assistance that helps to calculate an individual absolute lymphocyte count. In this post, we are going to tells you about an absolute lymphocyte count calculator and all you need to know about lymphocyte count.

Let’ start with the ‘lymphocyte definition.’

What Are Lymphocytes?

Lymphocytes are white blood cells that work in a human immune system or it can be said as one of the body’s main types of immune cells. According to experts, the Lymphocytes are made in the bone marrow and often found in the blood and lymph tissue. They assist to fight off diseases, so it’s normal to see a temporary increase after an infectious disease. These are the six main types of WBC’s an average percentage of each type in the blood:

  • Lymphocytes – 30 percent
  • Neutrophils – 58 percent
  • Eosinophils – 2 percent
  • Basophils – 1 percent
  • Bands – 3 percent
  • Monocytes – 4 percent

The absolute lymphocytes are only the thing that matters for tracking CLL progression.

Well, track lymphocytes absolute count with not the lymphocytes percentage; forget WBC or white blood cell count.

Remember that, when the lymphocytes absolute count doubles within 6 months are said to be as lymphocyte doubling time.

Formula For Absolute Lymphocyte Count:

The ALC formula is as follow:

ALC = WBC count x 1000 x %Lymphs


(WBC) represents the values of the white blood cell count

(LYMPH %) represents the lymphocyte percentage

Take this absolute lymphocyte count calculation formula into account to know about the absolute, high, low, normal lymphocyte count.

The above alc calculator also uses the same formula while calculating the lymphocytes absolute count.

Types of Lymphocytes:

Lymphocytes are mainly divided into T cells, B cells, and NK cells. Read on to know about these terms

T Cells:

T cells or T lymphocytes get their names as these cells are developed in the thymus gland. The T lymphocytes are assisting the body to kill cancer cells and even control the immune response to foreign substances. These cells are programmed to recognize, respond to and remember antigens. Studies show that T cells contribute to the immune defenses in two major ways – some direct and regulate immune responses and the others are able to destroy targeted cells on direct contact.

B Cells:

B cells or B lymphocytes are set to make one specific antibody. These cells are an important part of an immune system. B cells get their name as these lymphocytes mature in the bone marrow of humans, and even in the bursa organ of birds. Well, B cells are distinguished from other lymphocytes by a protein on their surface said to be as the B-cell receptor. Keep in mind, this protein is specialized to recognize and even attach to specific antigens. In simple words, these cells do their job to make antibodies that are protein produced by an immune system to combat foreign substances called antigens.

NK Cells:

NK or natural killer cells are lymphocytes that are said to be cytotoxic. NK cells also come from the same place as B and T cells. NK cells function similarly to cytotoxic T cells – people often confused that NK and T cells are the same, but they not! NK cells do not have T cell receptors or trigger antibody production, but NK cells are capable of distinguishing infected cancerous cells from normal cells.

Absolute Lymphocyte Count (ALC) Calculator:

The absolute lymphocyte count calculator is an advanced tool that helps to determine the ALC or abs lymphocytes. More specifically, this alc calculator estimates lymphocytes absolute count in the blood, this estimation is very useful in the assessment of the risk connected with viral infections and several other conditions like chronic lymphocytic leukemia and lymphomas.

For some people, the tool is referred to as lymphocytes count calculator. Well, this alc calculator uses the total white blood cell count, and the lymphocytes percentage to calculate ALC of one’s.

How to Use:

The above calculator is very convenient to use, you just have to input two fields to calculate your absolute lymphocytes count. Well, ahead to know the step-by-step guide of this absolute lymphocyte count calculator.

  • First of all, you ought to enter the total number of white blood cells (WBC) in the given field of the tool
  • Very next, you ought to enter the lymphocyte percentage in the field of ‘Lymphocytes.’
  • Finally, hit the calculate button of an above calculator to get absolute lymphocyte count

Remember That The white blood cells (WBC) should be reported in cells per cubic millimeter – for instance, enters 7.3 for 7300 WBC per cubic millimeter of blood!

Normal Ranges And Levels:

Optimistic studies reveal that lymphocyte levels can vary according to an individual’s race, gender, location, and even lifestyle habits.

According to experts, the normal lymphocyte count range in adults is between 1,000 and 4,800 lymphocytes in 1 microliter (µL) of blood. When it comes to children, the absolute lymphocyte count normal range is between 3,000 and 9,500 lymphocytes in 1 µL of blood.

Typically, high or low lymphocyte count can be a sign of disease.

So, what does it mean if levels are high or low! Read on to know more about them!

If Levels Are High:

Well, come the point, several studies show that abs lymphocytes range above the normal range can be harmless and said to be a temporary situation just because of the body’s normal response to an infection or inflammatory infection.

But, low lymphocyte count can also refer to a sign of lymphocytosis, which is a more serious condition.

Lymphocytosis is the condition that frequently associated with some blood cancers, chronic infections, and autoimmune diseases like inflammatory bowel disease.

In an adult, the lymphocytosis is corresponding to a lymphocyte count higher than 3,000 lymphocytes in 1 µL of blood, experts say. When it comes to children, it would be around 9,000 lymphocytes in 1 µL of blood, although this value can be varied with age.

If Levels are Low:

A low lymphocyte count below the normal range can say to be as temporary. The low absolute lymphocytes can occur when an individual prone to cold or another infection, or even be caused by intense physical exercise, malnutrition, or severe stress.

The absolute lymphocytes low can also refer as a condition known as lymphocytopenia or lymphopenia, usually occurs because

  • An individual body isn’t producing enough lymphocytes
  • Lymphocytes are being destroyed
  • Lymphocytes are trapped in an individual spleen or lymph nodes

Remember that Lymphocytopenia can also be occurring due to a side effect of medications or some other medical treatments.

A low lymphocytes count is a sign of lymphocytopenia change for adults and children. Several studies reveal that they are often less than 1,000 lymphocytes in 1 µL of blood for adults and less than 3,000 lymphocytes in 1 µL of blood for children.

What Causes A High Lymphocyte Count?

Lymphocytosis or a high lymphocyte count is very common if an individual had an infection. High lymphocyte levels may leads to a more serious illness or disease such as:

  • Viral Infections – such as (Measles, Mumps, and Mononucleosis)
  • Adenovirus
  • Hepatitis
  • Influenza
  • Tuberculosis
  • Toxoplasmosis
  • Cytomegalovirus
  • Brucellosis
  • Vasculitis
  • Acute Lymphocytic Leukemia
  • Chronic Lymphocytic Leukemia
  • HIV and AIDS


When to Worry About Low Lymphocytes?

Keep in mind, a low lymphocyte count cannot cause any signs or symptoms. Usually, the low lymphocytes symptoms are found when an individual is get tested for other diseases or conditions, such as AIDS.

Additionally, get a lymphocytes blood test and consult your doctor according to the results!

An individual may be at risk of lymphocytopenia

  • If an individual had a recent infection or surgery
  • If an individual have an underlying condition that can cause lymphocytopenia
  • If an individual intake any medications, which may affect higher lymphocyte count

So, if you have one of these, then there is a need to consult with medical experts ASAP!

Optimists studies reveal that if an individual has unusual infections, repeat infections, or such infections that won’t go away, then the health care provider may suspect that he/she have lymphocytopenia. Fever is the most common symptom of such an infection.

However, there are several other conditions that can cause lymphocytopenia such as

  • HIV and AIDS
  • Autoimmune Conditions – like Lupus
  • Undernutrition
  • Influenza
  • Some Cancers – such as (lymphocytic anemia, lymphoma, and Hodgkin disease)
  • Steroid Use
  • Radiation Therapy
  • Certain Drugs – like (Chemotherapy Drugs)
  • Some Inherited Disorders – including (Wiskott-Aldrich Syndrome and DiGeorge Syndrome)


Thankfully, the above absolute lymphocyte count calculator helps to calculate ALC. But, this tool takes into account for educational purposes only. Remember that, the outcomes should not be utilized for the diagnosis or treatment of any health problem or disease. Also, the result is not intended to replace clinical judgment, for the further query you have ahead to your Health Care Provider!
