Dr. Liu Feng
An elevated lymphocyte percentage refers to when the proportion of lymphocytes among the total white blood cell count exceeds the normal range in a complete blood count (CBC) test. The normal range for healthy adults is generally between 20% and 40%, and values exceeding 40% are considered high.
Common causes for an elevated lymphocyte percentage include:
1. Viral infections: During viral infections such as measles, rubella, or chickenpox, lymphocytes increase to fight the virus.
2. Lymphocytic leukemia: Abnormal proliferation of lymphocytes can lead to increased levels.
3. Organ transplant recipients may experience this condition following postoperative transplant rejection.
4. Chronic inflammation or prolonged immune system activation can also elevate the lymphocyte percentage.
5. A decrease in other types of white blood cells can cause the lymphocyte percentage to appear higher, even if the absolute number of lymphocytes remains unchanged.
An elevated lymphocyte percentage may be accompanied by symptoms such as fever, headache, sore throat, fatigue, and rash. If symptoms worsen or discomfort persists, prompt medical attention is recommended.
