What Is The Normal Range Of Lymphocyte Count

White blood cells in the human body are designed to defend the organism from external attacks. When leukocytes are low the patient is susceptible to infection. Lymphocytes are a type of white blood cell that is distinguished from the rest by a lack of granules, and they have a key role in the immune system as they are able to respond to unknown agents. If you wan to know about the normal range of lymphocytes, oneHOWTO can explain more.

Lymphocytes - A Normal Range

In blood tests, the lymphocyte level can be analysed, with their value will be seen in the CBC section. Its value is calculated per milliliter of blood, the normal range of lymphocytes is between 1300 and 4000 cells / ml. Take a look at the chart below to know the range of lymphocytes which is considered normal for your age group. In this case, all ranges are expressed in both percentages and ALC (absolute Lymphocyte count).

  • 0 to 6 days old: 26 - 36% (2000 - 11000 ALC)
  • 7 to 13 days old : 36 - 46% (2000 - 17000 ALC)
  • 1 to 5 months old: 43 - 53% (2500 - 16500 ALC)
  • 6 to 11 months old: 45 - 75% ( 4000 - 13500 ALC)
  • 1 to 3 years old: 50 -70% ( 3000 - 9000 ALC)
  • 4 to 9 years old: 40 - 60 % (2000 -8000 ALC)
  • 10 to 20 years old: 25 - 45% (1500 - 6500 ALC)
  • Over 20 : 18 - 44 % (1300 - 4000 ALC)

You may also be given a percentage, though these include T-cells, B-cells, and NK cells, this figure should be between 15% and 40% of White Blood Cells.

To know more about the state of the immune system it is a normally wise to measure and analyse the other types of leukocytes and interpret the results in the context of the patient's actual situation.

High lymphocyte counts

Values are high when the number of lymphocytes in blood test is above 4000 per milliliter. The rise in the number of lymphocytes is referred to as lymphocytosis and is indicative of an acute or chronic infectious processes such as mononucleosis, pneumonia, rubella or tuberculosis, ; drug allergies and linphoproliferativ processes such as leukemia.

Young children (from 1 to 4 years old) are considered to have lymphocytosis from when counts are above 9000 per milliliter whereas high counts in children from 5 to 12 years old are considered above 7000 per milliliter.

However, you should not immediately panic. There are many causes of a high lymphocyte count which we explain in our article what a high lymphocyte count means. As you know, this is just a guide, and only a doctor will be able to give you a reliable diagnosis.

What to do with a high lymphocyte count

As we've mentioned, a high lymphocyte count can be due to many circumstances and is probably the irrefutable sign of an underlying condition. Therefore, treatment to increase your lymphocyte count will depend on what you are diagnosed with.

However, there are certain habits that can help you lower high lymphocytes, such as avoiding sugary foods, increasing your intake of omega-3 fatty acids and improving your vitamin C and D intake. Moderate exercise is also recommended.

Low lymphocyte counts

This is called lymphopenia, when the number of lymphocytes is below 1300 / ml. Lymphopenia is commonly detected in individuals whose immune system is subjected to immuno suppressive treatments such as Chemotherapy. You can take a look at what happens if your lymphocytes count is low for more information.

It can also be presented in people with lupus,chronic uremia, AIDS, aplasticanemia, tuberculosis or Hodgkin's disease. However, low lymphocyte levels are also common during pregnancy, in which case, there is no need to worry.

What to do with a low lymphocyte count

On the other hand, as lymphopenia is usually caused by a weakened immune system, you'll need to work on boosting it. In this case, having a balanced diet based on mostly fruit and veg, complex carbohydrates and only healthy fats is primary. Increase your zinc (Maple syrup, Wattleseed, flaxseed, pumpkin seed ...), beta-carotene and keep as hydrated as you can, as well as lowering your stress levels significantly and doing regular exercise.

  • Having a high lymphocyte count is usually no surprise, as this is normally the consequence of having a certain illness.
  • When reading your blood test results, it's much more important to read the absolute number of lymphocytes rather than the percentage, as this will give you a more accurate idea of whether your lymphocyte range is normal.

We advise you not to worry if it's just 1% higher. If you want to be sure there is nothing to worry about you should discuss the results with your GP, but if the rest of the blood test has come out within average values we'd advise you not to worry too much.

Hello Vicky,

If you want to know the normal levels for haemoglobin, which differs between females and males, plus more information if you have a high count, please read this article:

This should answer your question and more.

I am 53 years old my WBC is 3.58 and my lymphocyte level is 45.4%.
my UTI tests shows that i have an infection could be the reason?
Alice T Breeze
Yes, an infection can cause a variation in lymphocyte count.
Make sure you discuss the results with your doctor.
