Most high lymphocyte counts are caused by viral or bacterial infections. Very rare cases may suggest aplastic anemia or leukemia may be possible.
Lymphocytes are a type of white blood cells. In the peripheral blood of normal human beings, the number of lymphocytes is high, with an absolute value of (0.8~3.5)×10^9/L, accounting for 20%~40% of the total number of white blood cells.
1. The percentage of lymphocytes is physiologically elevated in children under five years of age.
2. In pathological cases, high lymphocyte counts are caused by viral or bacterial infections. Common viral colds are the most common. Other viruses include: measles, chicken pox, viral hepatitis, and mumps. After aggressive antiviral treatment (acyclovir), lymphocytes usually return to normal when the condition improves.
In addition, high lymphocyte counts can also be seen in chronic lymphocytic leukemia and non-Hodgkin’s lymphoma.
Patients with elevated lymphocyte counts, especially those with fever, fatigue, muscle aches, rash, cough, etc., should go to the hospital promptly. Specific disease diagnosis and treatment should be carried out under the guidance of physicians.
