What Is The Normal Range Of Lymphocyte Count

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. You'll find all the treatments according to the source of the problem in our article on how to treat lymphocytosis.

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.

My lymphocyte count is regularly below range ie 0.99 x 10 9/L range is (1.00 - 4.00). What should I be asking my GP about this? Many thanks Susan Smith

Hi there Mohamed,
It does seem pretty high, which is why we suggest you run the results past your doctor so that he or she can check on the rest of your blood test.
Hope this helps

Your lymphocyte count is slightly over average, which is why we recommend you visit your doctor so he/she can take a closer look at your blood test.

I have been diagnosed with anemia about a year ago. my recent tests show iron levels are good, however I have a low platelet count, a high RDW and high lymphocytes.... I feel like i am getting a run around with the doctor... should i be looking at this as more than just simply anemia?

There are many reasons why you may have a high RDW and high lymphocyte count. If you have been ill with a viral or bacterial infection lately, this may show in your test results.
If you feel worried, you should ask your doctor for a check up in order to discard any serious illnesses.
Hope this helps

Sorry, but your charts are not making any sense. My recent blood test indicated a "HI" Lymphocytes . The reading on my sheet says : Flag results HI 4.0 reference 1.0 -3.5 xE9/L
Also my test on RDW registers Flag results HI 14.7 reference 11.5 -14.5 %
I am quite confused at these readings and would appreciate if you put some meaning in to it.
Regards ,

My CBC indicated 4450 lymphocyte count. I also have high TSH but normal levels of T4 and T3. Should I be worried?
My Lymphocytes are 6.0% (x10^9/L = 0.64) 2.00 - 7.50.
I have no idea what this means. Or if I should be worried.

Hi Chloe, this measurement sounds pretty low, although we don't understand if the figures are measured in cells/milliliter as the seem to be expressed in liters. This is why we suggest you show the results to your doctor so he/she can analyse them correctly.
Hope this helps
my lymph fluid is 89%
have a blood test evey year, allways perfect, the lastone my lymphocytes were 17,2, is that something to worry about?

Hi there,
It's not excessively low, so make sure you ask your doctor about the results, though it's not an alarmingly low count to be sure.
Hope this helps
Hi my name is Kevin for I've been battling something for a yr now and still feel weak. I have charcoal Marie tooth disease. Before a yr ago I weighed 175 lbs and felt strong. Now I weigh 155 and am weak tired and can't do much like I used. My wbc count has been up and below normal and just above normal and my lympcyte count is 1.2. The docs just say I'm healthy but I ffeel like dirt. I need help.

Although you should always follow your doctors' orders, we can advise you to take energy boosting natural products such as ginkgo biloba and add plenty of vegetable protein to your diet.
Believe it or not, exercising regularly can build up your energy.

Hope this helps
