When a disease attacks, in most cases, the body announces it through symptoms that should not be ignored, especially if they are constant and go to the doctor. However, sometimes diseases do not warn, at least not in a way that is easy to identify.

Such is the case that we will talk about today, the lymphocytosiswe will discover what its causes are and when to go to the hospital, according to information from Mayo Clinic, a renowned non-profit organization specialized in health.

Lymphocytosis, also known as elevated lymphocyte count, is an increase in white blood cells or lymphocytes, which help fight diseases. It is common for the lymphocyte count to increase briefly after an infection.

A count much higher than 3,000 lymphocytes in a microliter of blood is considered lymphocytosis in adults.

For its part, in children the number of lymphocytes for lymphocytosis varies with age and can reach 8 thousand lymphocytes per microliter.

It is worth mentioning that lymphocytosis figures may also differ depending on the laboratory.

It is possible to have a higher than usual lymphocyte count but have few, if any, symptoms. The highest count usually occurs after an illness.

Most of the time it is harmless and doesn’t last long, but a higher count could be the result of something more serious, such as a blood cancer or a chronic infection. By performing more tests, you can find out if the lymphocyte count is a cause for concern.

A high lymphocyte count may indicate:

  • Infection, whether bacterial, viral or another type.
  • Cancer of the blood or lymphatic system.
  • An autoimmune disease that causes continuous, or chronic, swelling and irritation, known as inflammation.

If you experience any discomfort, the ideal is to go to the doctor (Illustrative Image Infobae)

Causes of lymphocytosis include:

  • acute lymphocytic leukemia
  • Babesiosis
  • Brucellosis
  • Cat-scratch disease
  • Chronic lymphocytic leukemia
  • cytomegalovirus infection
  • Hepatitis A
  • Hepatitis B
  • Hepatitis C
  • Hypothyroidism (underactive thyroid)
  • Lymphoma
  • Mononucleosis
  • Severe medical stress, for example due to trauma
  • Smoking habit
  • Splenectomy
  • Syphilis
  • Toxoplasmosis
  • Tuberculosis
  • Whooping cough

A high lymphocyte count is usually detected by tests done for other reasons or to help diagnose another condition.

That is why it is recommended to have scheduled check-ups with the doctor to avoid this or other diseases that do not present visible or easily detectable symptoms and to be able to combat them in time. Remember that the sooner it is, the easier it is to combat a condition, including cancer.

Talk to a member of your healthcare team about the meaning of your test results. An elevated lymphocyte count and the results of other tests could indicate the cause of your illness.

Often, follow-up tests over several weeks show that the lymphocytosis has disappeared. Special blood tests may be helpful if the lymphocyte count remains high. If the condition persists or the cause is unknown, you may be referred to a doctor who specializes in blood diseases, called a hematologist.
