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 millilitre of blood, the normal range of lymphocytes is between 1300 and 4000 cells / ml.
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 leucocytes 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 millilitre. The rise in the number of linfocytes 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 0 to 4 years old) are considered to have lymphocytosis from when counts are above 9000 per millilitre whereas high counts in children from 5 to 12 years old are considered above 7000 per millilitre.
If you want to know more, take a look at what a high lymphocyte count means and make sure you know the cause.
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.
