Absolute monocyte count is an indicator of white blood cells in routine blood tests, which are commonly seen in laboratory results. Absolute monocyte count is an alias for monocyte count, the largest white blood cell in the blood, which is an important part of the body’s defense system and has a strong phagocytic and defensive capacity. High absolute monocyte count may be seen in physiological or pathological conditions, and the interpretation of the test results needs to be analyzed by the doctor in conjunction with medical history, symptoms, signs and other ancillary test results. Therefore, it is recommended that patients consult their physicians promptly to identify the cause. There are several common cases of high absolute monocyte values: 1. Physiological cases: Infants and children can have slightly high absolute monocyte values, which are physiological in nature and do not require special treatment if they do not have other uncomfortable symptoms. Pathological conditions: 1. Infectious diseases: such as Listeria monocytogenes infection, infective endocarditis, malaria, active tuberculosis, typhoid fever and other acute infectious diseases or the recovery period of acute infection, can be seen in the absolute value of monocytes significantly increased. It may be accompanied by other uncomfortable symptoms, such as infective endocarditis often accompanied by fever, skin mucosal petechiae, etc. Malaria often accompanied by high fever, chills, sweating, muscle aches, etc. 2. Blood diseases: such as monocytic leukemia, recovery from granulocyte deficiency, lymphoma, Hodgkin’s disease, myelodysplastic syndrome, multiple myeloma, chronic granulocytic leukemia, etc., all can show an absolute monocyte value Elevated absolute monocyte values. It can be accompanied by related symptoms, such as monocytic leukemia often accompanied by dizziness, fatigue, panic, bleeding and other symptoms, and lymphoma often accompanied by painless lymph node enlargement, fever, etc.; 3. connective tissue diseases: such as systemic lupus erythematosus, rheumatoid arthritis, etc., patients can be examined with high absolute monocyte values. Patients with systemic lupus erythematosus may have a rash, fever and muscle and joint pain, while rheumatoid arthritis may have swollen, painful, stiff joints and limited activities. 4. Malignant tumors: such as gastric cancer and liver cancer. Usually, it can be accompanied by other symptoms, such as abdominal pain, indigestion, and wasting in stomach cancer, and pain in liver area, fever, jaundice and ascites in liver cancer.
