What is lymphocyte culture + interferon?

Lymphocytes are a type of cell tissue produced by the body's lymphatic organs. Normally, lymphocytes circulate in the human blood or lungs. Abnormalities in lymphocytes can easily lead to some physical diseases, which are very harmful to the body's health. Lymphocyte culture plus interferon is a detection method. If infected with bacteria, it can easily lead to lung diseases.

Lymphocyte culture + interferon

A negative interferon release test indicates that the possibility of infection with tuberculosis bacteria is low and tuberculosis can be basically ruled out.

Common symptoms of pulmonary tuberculosis include cough and sputum, fatigue and night sweats, low-grade fever in the afternoon, and occasional coughing up blood. Comprehensive analysis including free chest X-ray, sputum smear, and sputum culture is required at a tuberculosis specialist clinic.

1. Diagnostic criteria for lymphocyte percentage:

The normal reference value for lymphocyte percentage is 20%~40%. The absolute value of peripheral blood lymphocytes exceeding 4.0×109/L is called lymphocytosis; the absolute value ≥15×109/L is considered a severe increase.

2. What is the reason for the high lymphocyte percentage?

1. Infection

If you have had an infectious disease recently, and it is a viral infection. It is usually caused by a viral cold, such as chickenpox, measles, viral hepatitis, whooping cough, tuberculosis, brucellosis, syphilis, etc. In addition, tumor diseases such as leukemia, lymphoma, recovery from acute infectious diseases, and after organ transplantation can all lead to an increase in lymphocytes.

2. Lymphocytic leukemia

Such as lymphoma. Lymphocytic leukemia is a disease characterized by widespread abnormal proliferation of leukemia cells, mainly immature lymphocytes, in the bone marrow and other hematopoietic tissues, and infiltration of other tissues and organs, leading to failure of normal hematopoietic function, manifested as a significant decrease in normal hematopoietic cells. It is related to the high percentage of lymphocytes. Bone marrow puncture and bone marrow examination are required for diagnosis.

3. What are lymphocytes?

Lymphocytes are a type of white blood cells. Produced by lymphoid organs, it is an important cellular component of the body's immune response function. Lymphoid organs can be divided into two categories according to their occurrence and function: central lymphoid organs (also known as primary lymphoid organs) and peripheral lymphoid organs (also known as secondary lymphoid organs). The former includes the thymus, bursa or its equivalent organ (some people believe that it is the bone marrow in mammals). They can continue to proliferate lymphocytes without antigen stimulation and transfer them to peripheral lymphoid organs after maturity. The latter includes spleen, lymph nodes, etc. Mature lymphocytes need to rely on antigen stimulation to differentiate and proliferate, and then exert their immune function.
