Low absolute value of lymphocytes may be caused by infection, tuberculosis, immune disease, blood disease and other conditions.
Lymphocytes are a type of white blood cells, mainly produced by lymphoid organs, with an absolute value of (0.8~3.5)×10^9/L. Low values of this value can be seen in conditions such as infections, tuberculosis, immune disorders, and blood disorders.
1. In viral infections, such as HIV infection, the patient’s absolute lymphocyte value will be low.
2. In case of Mycobacterium tuberculosis infection, the patient’s absolute lymphocyte value may also be lowered.
3. At the same time, the presence of rheumatoid arthritis, systemic lupus erythematosus and other immune diseases, or the use of adrenocorticotropic hormone, alkylating agents, anti-lymphocyte globulin, etc., can also induce the absolute value of the lymphocyte is low, and can be related to radiation damage.
4. Aplastic anemia, acute leukemia, etc. can also have low absolute lymphocyte values.
However, low absolute lymphocyte counts are not directly diagnostic of the disease, and patients need to combine the medical history, symptoms, signs and other test results with the doctor’s guidance to make a comprehensive judgment.
In addition to the above, low absolute lymphocyte count may also be caused by aplastic anemia, acute myeloid leukemia, etc. It is recommended that patients with low absolute lymphocyte count should consult a doctor for a clear diagnosis in a timely manner, and then undergo treatment according to the cause of the disease, so as to avoid delaying the condition.
