First, neutrophils, one of the white cells, have phagocytosis and bactericidal functions, which are related to the body's defense and the anti infection process. If the count of leukocyte and granulocyte was normal and the percentage of pure neutrophils was slightly lower, there was no obvious pathological significance.
Secondly, as the percentage of neutrophils low at the same time, accompanied by white blood cell number or neutropenia, is found in a variety of infections, such as viral infections (hepatitis, influenza, rubella), bacterial infection (typhoid, melitense), chemical and physical factors (such as drugs, poisons, radioactive, toxic or allergic benzene material) caused by
Finally, if you find that your percentage of granulocytes is low, but the lymphocyte ratio is high, it means that you may have caught a cold now and have been infected by a virus.

It's just a low ratio. Generally, it will not affect anything, because there are many factors that affect the inspection result. For example, whether the food structure before examination and whether there is sleep problem may also be affected. And other indicators are normal, absolute values are normal, then do not need to care about.

The expression of neutrophils is the decrease in the total number of leukocytes, but mainly neutrophils. When the absolute value of neutrophils is less than 1.5 * 109/L, it is called granulocytopenia, and it is called granulocytic deficiency when it is below 0.5 x 109/L. There are many causes of neutrophils, which can be summed up in the following aspects:
(1) infectious disease: virus infection is a common cause of granulocytic reduction, such as influenza.
(2) blood system disease: granulocytosis is common in aplastic anemia, acute leukemia, and severe iron deficiency anemia.
(3) physical and chemical factors: radiation, chemical substances and drugs can cause granulocytic reduction. Neutrophils, such as antipyretic analgesics, antibiotics (chloramphenicol), sulfonamides, and some hypoglycemic agents, can be caused by neutrophils.
(4) hyperfunction of mononuclear macrophage system, such as hypersplenism and some malignant tumors.
(5) other: systemic lupus erythematosus, some autoimmune diseases, anaphylactic shock, etc. may also have neutrophils.

What are neutrophils, low neutrophil in our life situation see, the low neutrophil is aware of it, the reason for low neutrophil to understand how much, let us try to understand the neutrophils.
In our usual life, physical examination in the hospital, our blood, the blood routine examination data, doctors can more accurately help us determine the physical problem, which is the percentage of neutrophils in our daily life frequently encountered symptoms, generally by a cold virus is likely to cause such symptoms.
What is the low percentage of neutrophils
Neutrophils originate in bone marrow hematopoietic stem cells
Neutrophils originate in the bone marrow hematopoietic stem cells and enter the blood or tissue after the differentiation and development of the bone marrow. The number of distribution in the bone marrow, blood and connective tissue ratio is 28:1:25, the total number of Yuezhanbai neutrophils in the blood of 55% adults 70%.
Neutrophils are one of the polymorphonuclear leukocytes, with the largest number in the granulocytes, so some people refer to polymorphonuclear leukocytes to neutrophils. The cells contain many unique particles dispersed small pink or light purple, particles containing myeloperoxidase, acid phosphatase, lysozyme and phagocytin etc..
Myeloperoxidase specific neutrophils, even in macrophages that are strong in few or without this enzyme, are phagocytic. Cytochemistry, which is usually marked by the myeloperoxidase in neutrophils. Neutrophils have strong chemotaxis.
The so-called chemotaxis is the movement of a cell in the direction of a chemical substance. Substances that play a chemotaxis to neutrophils are called neutrophil chemokines. There is a chemokine receptor on the neutral cell membrane, which binds with chemokines, activates the calcium pump on the cell membrane, and extends the cells to the front foot to make the cells move towards the location of chemokine.
After contacting with the foreign bodies that produce chemokines, the cytoplasm of the neutrophilic cells form a protrusions around the contact points, namely, the pseudo fovea, the cell membrane underlying the contact part, and the foreign bodies surrounded, forming the phagocytic bodies or phagocytic vesicles containing foreign bodies. The membrane of neutrophils has IgGFc receptor and complement C3 receptor on the surface of neutrophil, which can accelerate phagocytosis.
When the phagocytic foreign body is wrapped with antibodies and complement, it binds with the corresponding receptors on the neutrophil membrane, and strengthens the phagocytosis of cells, which is called conditioning.
The respiratory burst caused by the disorder of the cell membrane as the cell phagocytosis begins.
With the initiation of cell phagocytosis, the respiratory burst caused by the disorder of cell membrane and the increase of oxygen consumption of cells lead to a large number of peroxide and superoxide and other cytotoxic effector molecules, which have cytotoxic activity to parasites. Stimulated by interferon - gamma and tumor necrosis factor, it can produce more anions of oxygen metabolism and kill extracellular parasites.
Neutrophils also die after killing foreign bodies such as phagocytic bacteria, and the dead neutrophils are called purulent cells.
When neutrophils are affected by bacterial products and antigen antibody complexes, the granular content of the cells is released to the cells. The release of acidic protease and neutral protease can decompose the vascular basement membrane, glomerular basement membrane, collagen and elastin in connective tissue, complement C5, C15 and kinin in plasma.
Some of the decomposition products are neutrophil chemokines, which can attract more neutrophils. Among the substances released from neutrophils, there are eosinophil chemokines, neutrophil immobility factor (NIF), kininogen, plasminogen, coagulation factor and leukotriene.
