Lymphocyte count 3.5, refers to a lymphocyte count of 3.5 x 10^9/L. With a lymphocyte count of 3.5 x 10^9/L, this value is normal.
The lymphocyte value is obtained by counting lymphocytes under a microscope to get the number of lymphocytes contained in each liter of blood.
Normally, the adult peripheral blood lymphocyte value is (0.8~4) x 10^9/L. Children under 4~6 years of age have a higher lymphocyte value, which gradually approaches that of adults around 4~6 years of age. Therefore, a lymphocyte value of 3.5 x 10^9/L is the normal range.
Lymphocyte counts are commonly used in the diagnosis of infectious diseases and blood disorders, among others. When its absolute value and percentage increase, it indicates the presence of various viral infectious diseases such as whooping cough, tuberculosis and other specific infections. High lymphocyte count is also seen in lymphocytic leukemia, infectious lymphocytosis and other diseases.
In case of abnormal lymphocyte counts, it is advisable to consult a physician for a definitive diagnosis in order to avoid delays.
