Is High Lymphocyte Count Good or Bad for Your Health?

Introduction

Lymphocytes are a kind of white blood cell. They are the primary type of cells found in the spleen, tonsils, and lymph nodes and are therefore called lymphocytes. They play a vital role in your immune system, which enables your body to combat infection and disease. Two types of lymphocytes are found in the body: T cells and B cells. Each type plays a significant role in your immune system.

Lymphocytes are spheroidal and almost composed of a nucleus. They are not seeable through the naked eye, but when examined under a microscope, lymphocytes appear to be bigger than RBCs, or red blood cells, but fewer in number. Lymphocytes comprise around 20% to 40% of all WBCs or white blood cells.

The question is, is a high lymphocyte count good or bad for your health? A high lymphocyte count in the body can indicate an illness or disease of your immune system. A low lymphocyte count can suggest your immune system is not functioning as well as it should, and you might be at a higher risk of getting infections.

What Is a Normal Lymphocyte Count?

A normal lymphocyte count differs with age. For fit adults, the range is from 1,000 to 4,800 cells per microliter of blood (cells/mL). For children, the range is from 3,000 to 9,500 cells/mL.

Having too many lymphocytes in your bloodstream is called lymphocytosis while having too less lymphocytes is called lymphopenia. Lymphocytosis is a sign that the immune system has been triggered in response to a disease or medical condition. It may be an expression of an infection or cancer of the blood or lymphatic system, among other things.

High Lymphocyte Symptoms 

Lymphocytes with a high concentration can cause the following symptoms:

  • Enlarged and painless lymph nodes (Lymphadenopathy)
  • Fatigue
  • Fever
  • Pain in the upper part of the abdomen due to an enlarged spleen (splenomegaly)
  • Weight loss, and so on

Lymphocytosis is quite common, primarily among people who have had a recent illness. It is common to have a temporary increase in lymphocytes after your body has battled off a disease, especially a viral one.

Tests for high lymphocytes in the immune system

If you are experiencing such symptoms, you should definitely visit a physician and get tested. Tests are of two types:

  • A Complete Blood Count test- which is capable of disclosing the percentage of each white blood cell type present in your blood, including lymphocytes.
  • The Flow Cytometry test- which is a much more advanced test that can identify and count the respective cells in your blood, including lymphocytes.

High Lymphocyte Causes

Lymphocytes high in number are probably caused by the following:

  • Acute Lymphoblastic Leukemia
  • Chronic Lymphoblastic Leukemia
  • Hepatitis A, B, and C
  • Lymphomas 
  • Pertussis
  • Syphilis
  • Toxoplasmosis
  • Hypothyroidism
  • Tuberculosis 

Are Lymphocytes High in A Number Good or Bad for Your Immune System?

The answer is not always. A high lymphocyte count indicates that your body’s immune system is fighting an illness. It is generally temporary and harmless. It usually goes away when your underlying infection improves. But at times, a high lymphocyte count can be due to a severe condition like the one mentioned before, so it is always advisable to consult a doctor on bearing the symptoms.

Conclusion

It is advised to be under your physician’s supervision so your body’s lymphocyte count is controlled, as it might result in several other conditions. But you should keep in mind that the lymphocyte count varies with age and people, so there is no need to worry about that instead, take a test to find out for sure.
