neutrophilic granulocytes

Neutral lobular granulocytes are excessively lobulated neutrophils, which can be divided into 4 leaves or even 5 to 6 leaves. If 5 leaves exceed 0.05, they are also called neutrophils. It is caused by a lack of hematopoietic substances, which causes deoxyribonucleic acid synthesis, or a decrease in hematopoietic function. Mainly seen in the megaloblastic anemia, pernicious anemia and the application of anti-metabolite drugs, the recovery period of infection, there may also be a transient nuclear right shift phenomenon. Basic Information Specialist classification: growth and development examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Tips: No smoking, pay attention to rest. Normal value White blood cell automatic counter (2 ~ 7) × 109 / L (2000 ~ 7000 / mm3). Clinical significance Abnormal result Increased proportion of neutral lobular granulocytes 1. May be an acute infection, may have local infections such as phlegm, carbuncles and so on. It may also be a systemic infection including pneumonia, sepsis, suppurative tonsillitis, purulent meningitis, epidemic cerebrospinal meningitis, rheumatic fever, acute appendicitis, diphtheria, acute cholecystitis, and the like. 2. May be lead, mercury, sleeping pills, digitalis, antipyrine, arsenic poisoning, insect toxic, heterologous protein absorption. It may also be metabolic uremia, diabetic ketoacidosis, gout, pregnancy poisoning, etc. 3. Blood diseases such as acute massive hemorrhage, acute hemolysis, acute and chronic granulocyte leukemia, Hodgkin's disease, polycythemia vera, etc. 4. Tissue necrosis myocardial infarction, gangrene, neonatal necrosis, burns, etc. 5. Others such as cerebral hemorrhage, brain tumors, postoperative surgery, Cushing's syndrome, mucinous edema, malignant tumors, cachexia, etc. may also cause a proportion of neutral lobular granulocytes. Neutral lobular granulocyte ratio reduction 1. Severe infections such as severe sepsis, miliary tuberculosis, etc. 2. Special infections such as typhoid fever, paratyphoid fever, viral infectious diseases, rickettsial infection, protozoal (malaria, black fever, protozoal infection). 3. May be aplastic anemia, pernicious anemia, leukopenic leukemia, acute and chronic lymphocytic leukemia, malignant lymphoma, multiple myeloma, paroxysmal nocturnal hemoglobinuria and other blood diseases. 4. The effects of organic lysozyme, anti-tumor drugs, anti-thyroid drugs, anti-caries drugs, sulfonamides, phenothiazines, chloramphenicol, and oxytetracycline. 5. Radiation exposure to radiation sickness, etc. 6. Systemic lupus erythematosus, Banti syndrome, cirrhosis, Felty syndrome, etc. can also cause a proportion of neutral lobular granulocytes. 7. Congenital diseases, periodic neutropenia, congenital neutropenia, familial benign eosinophilia, etc. 8. Others may also be cachexia, hemodialysis, etc. People who need to be examined: People who are suspected of having blood diseases or infections. People with inflammatory manifestations. Low results may be diseases: high fever fever results may be diseases: diphtheria, appendicitis, typhoid, gout precautions Unsuitable for people: people with leukemia, people with platelet deficiency. Forbidden before inspection: No smoking, pay attention to rest. Inspection process Blood was taken to check the number of neutral lobular granulocytes. Not suitable for the crowd 1. Patients who have taken contraceptives, thyroid hormones, steroid hormones, etc., may affect the results of the examination and prohibit patients who have recently taken the drug history. 2, special diseases: patients with hematopoietic function to reduce disease, such as leukemia, various anemia, myelodysplastic syndrome, etc., unless the examination is essential, try to draw less blood. Adverse reactions and risks 1, subcutaneous hemorrhage: due to pressing time less than 5 minutes or blood draw technology is not enough, etc. can cause subcutaneous bleeding. 2, discomfort: the puncture site may appear pain, swelling, tenderness, subcutaneous ecchymosis visible to the naked eye. 3, dizzy or fainting: in the blood draw, due to emotional overstress, fear, reflex caused by vagus nerve excitement, blood pressure decreased, etc. caused by insufficient blood supply to the brain caused by fainting or dizziness. 4. Risk of infection: If you use an unclean needle, you may be at risk of infection.
