What Is the Normal Range Of Lymphocytes in Humans?

What do you typically understand about lymphocytes? Well, this is a type of white blood cell that enables your immune system to combat foreign bacteria, viruses and terrible health issues such as cancer. You can learn about your lymphocyte count by opting for a blood test; that’s it. Lymphocyte levels typically depend on the sex, age, race, lifestyle and altitude of an individual. Lymphocytes normal range in adults is between 1000 and 4800 in every 1 microliter of blood. On the other hand, the normal range is between 3000 and 9500 in children.

Once the formation of these lymphocytes is done and dusted, they tend to perform a lot of functions within the lymphatic system. Now, what is a lymphatic system? It is an open network of organs, tissues and vessels that function in a collaborative manner, thus maintaining body fluid levels, protecting your body from foreign invaders and removing cellular waste. For more information, all you need to do is take a quick look at this article right away. Delve deeper and keep reading. 

What Are the Reasons Behind a Low Lymphocyte Count? 

An individual with low lymphocyte count often ends up suffering from lymphocytopenia. Some of the causes are stated below in this article: 

  • Your body has stopped producing the required amount of lymphocytes
  • Your body’s lymphocytes are getting damaged due to some reasons 
  • Lymphocytes are trapped in your lymph nodes or spleen
  • AIDS and HIV 
  • Undernutrition 
  • Autoimmune conditions like lupus 
  • Influenza 
  • Some types of cancers, such as lymphoma, lymphocytic anemia and Hodgkin’s disease 
  • Radiation therapy 
  • Steroid use 
  • Some types of drugs, such as chemotherapy drugs 
  • Certain inherited disorders like DiGeorge syndrome and Wiskott-Aldrich syndrome 

What Are the Reasons Behind a High Lymphocyte Count? 

Sometimes, the lymphocytes normal range extends due to prior infection. Some of the causes behind lymphocytosis are as follows? 

Viral infections such as mumps, measles and mononucleosis 

  • Hepatitis 
  • Adenovirus 
  • Tuberculosis 
  • Influenza 
  • Cytomegalovirus
  • Toxoplasmosis 
  • Vasculitis 
  • Brucellosis 
  • Chronic lymphocytic leukemia 
  • Acute lymphocytic leukemia 
  • AIDS and HIV

What Are the Two Different Types of Lymphocytes? 

The two different types of lymphocytes are: 

  • T Cells or T Lymphocytes

T cells are responsible for controlling the immune system response of your body. Other than that, these types of lymphocytes attack and kill tumor cells and infected cells directly. Activation of T cells in your body paves the way toward the growth of several types of T cells. Some of them are stated below in this article: 

  • Cytotoxic (killer) T cells: These kinds of cells tend to attach to antigens on abnormal or infected cells. After that, the Cytotoxic T cells destroy the infected ones by inserting enzymes into the cells and making holes in the cell membranes. 
  • Regulatory (suppressor) T cells: These cells are responsible for preventing harmful responses from taking place. 
  • Helper T cells: Helper T cells assist the rest of your immune cells in an effortless manner. Certain T cells are solely responsible for making antibodies against different kinds of foreign invaders. The remaining ones help in the process of activating cytotoxic T cells. 

Now, let’s gain some valuable insights about the B cells. 

  • B Cells or B Lymphocytes 

The primary aim of B cells revolves around making antibodies. These antibodies are nothing but proteins that help to target bacteria, viruses and different foreign invaders. These B cells come well-equipped with receptors on the surfaces. By recognizing the wide range of antigens, these cells focus on producing specific antibodies to attack. Check out the two types of response at a quick glance: 

  • Primary immune response: The B cells get stimulated the moment an antigen gets attached to a receptor. While some of them convert themselves into memory cells, the remaining ones get transformed into plasma cells. These plasma cells take care of producing an antibody to the specific antigen. 
  • Secondary immune response: If the B cells in your body come across an old antigen, the memory cells quickly multiply by remembering it. By changing themselves into plasma cells, they produce the right kind of antibody. 

What Are the Symptoms of Lymphocyte Conditions? 

High lymphocyte count in an individual’s body might expose them to some of the common symptoms. Keep reading to uncover them right away: 

  • Night sweats 
  • Swollen lymph nodes 
  • Abdominal pain 
  • Fever 
  • Loss of appetite 
  • Shortness of breath 

Under such scenarios, all you need to do is get in touch with a well-reputed healthcare provider, and that’s it. For instance, you can always rely on the high-quality services offered by Apollo Hospitals. The trained professionals will strive hard while helping you combat the given health issue. 

What Tests Can You Perform While Checking the Health of Your Lymphocytes? 

You can perform these two tests to generate the desired results: 

  • Flow cytometry
  • Absolute lymphocytes count 

The Bottom Line 

Hopefully, you are now quite aware of lymphocytes’ normal range, their different types and their causes. Instead of keeping these health conditions untreated and unaddressed, you should focus on finding the perfect solution as soon as possible.
