What is the Normal Range for Lymphocyte Count in a Blood Test?

The normal value for lymphocyte ratio in blood routine examination is between 20% and 40%, and the absolute value is between (0.8-4) x 109/L. However, specific situations still need to be consulted with a doctor for further understanding. Lymphocytes in blood routine examination are a type of white blood cells that possess specific immune recognition functions in the human body, including anti-infection and anti-tumor effects. Clinically, they can be used to assist in the diagnosis of bacterial infections, viral infections, and other diseases. If the lymphocyte ratio in blood routine examination is below 20% or above 40%, or if the absolute value is below or above (0.8-4) x 109/L, it is mostly considered to be abnormal. If the examination results are abnormal, it may be due to diseases such as body infection, radiation exposure, aplastic anemia, etc. It is necessary to go to the hospital for further examination through bacterial culture, bone marrow aspiration, imaging examination, and other related tests. At the same time, appropriate treatment should be taken according to the cause to avoid affecting physical health. In daily life, it is important to cultivate good habits, maintain a healthy diet, pay attention to rest, and exercise appropriately. If there is a disease, it is necessary to actively treat it under the guidance of a doctor and regularly go to the hospital for follow-up to prevent other symptoms and affect the recovery of the disease.
