1. Low absolute neutrophil value may be caused by physiological factors, such as taking medication, etc., which can return to normal by itself.
2. Low neutrophils may be caused by pathological factors, such as viral infections, hematologic diseases, long-term radiotherapy, cirrhosis of the liver and other causes.
(1) Viral infections, such as influenza, measles, and some bacterial infections, such as typhoid fever, can lead to low neutrophils.
(2) Blood system diseases, such as aplastic anemia can lead to lower neutrophils.
(3) Long-term radiotherapy patients or exposure to X-rays may show a decrease in the absolute value of neutrophils.
(4) Patients with cirrhosis and non-cirrhotic portal hypertension presenting with splenomegaly with hypersplenism can destroy leukocytes and platelets, which can lead to a decrease in absolute neutrophil values.
In addition, it is recommended that patients with low absolute neutrophil values should go to the hospital in time for relevant examinations and be treated under the guidance of doctors.
