Neutrophil count is one of the indicators in the routine blood test, because neutrophils are often involved in the immune response, so the neutrophil count can reflect the level of the body’s immune function, and low neutrophil count is often seen in some infectious diseases, hematological disorders, and patients with radiotherapy, and so on.
Neutrophils are derived from bone marrow, which is an important component of the innate immune system, and are named after the many particles contained in the cells, which are mostly lysosomes containing myeloperoxidase, lysozyme, alkaline phosphatase, and acid hydrolase and other abundant enzymes, the presence of which gives neutrophils phagocytosis and digestion functions, and participates in immune reactions.
In some infectious diseases, such as typhoid fever, paratyphoid fever, measles and other infectious diseases, low neutrophil count can be seen.
Low neutrophil count can also be seen in some hematologic diseases, such as aplastic anemia, granulocyte deficiency, myelodysplastic syndromes, and so on.
Low neutrophil counts can also be seen in some patients undergoing radiation or chemotherapy due to bone marrow suppression.
Low neutrophil count can also be seen in other diseases, it is recommended to seek medical treatment as soon as possible, and go to a regular hospital to find out the cause, so as not to delay the condition.
