neutrophils

Neutral rod-shaped granulocytes are rod-shaped neutrophils in the lobulation of peripheral blood neutrophils. The normal ratio between the rod-shaped core and the leaf-core nucleus is 113, which is also called the nuclear left shift. Common in infections, especially acute infections caused by pyogenic bacteria, can also be seen in acute poisoning, acute hemolysis, acute blood loss. 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 The proportion of neutral rod-shaped nucleated cells in peripheral blood should be 5% to 6%. Clinical significance abnormal situation 1. Rod-shaped granulocytes >0.06, called mild left shift. Common in infection (especially acute suppurative infection), acute poisoning, acute hemolysis, acute blood loss. 2. Rod-shaped granulocytes >0.10 with a small number of late-onset granulocytes are moderately left-shifted, indicating a serious infection. 3. Rod-shaped granulocytes >0.25 and more naive granulocytes, severe left nucleus, common in granulocyte leukemia or neutrophilic leukemia-like reactions. Need to check the crowd: people suspected of having blood diseases such as leukemia and infection. Low results may be diseases: combined immunodeficiency disease, pediatric acquired immunodeficiency syndrome results may be high disease: acute hemorrhagic anemia, chronic myeloid leukemia, acute poisoning in children, acute toxic encephalitis precautions Not suitable for people: people with platelet deficiency. Forbidden before inspection: No smoking, pay attention to rest. Inspection process Vascular blood collection was used for testing. Before venous blood collection, carefully check that the needle is securely installed and that there is air and moisture in the syringe. The needle used should be sharp, smooth, ventilated, and the syringe should not leak. Firstly, the skin was disinfected from the inside to the outside and clockwise from the selected venipuncture with a 30g/L iodine swab. After the iodine was volatilized, the iodized trace was wiped out in the same way with a 75% ethanol swab. Fix the lower end of the venipuncture site with the thumb of the left hand, hold the syringe syringe with the thumb and middle finger of the right hand, and fix the needle lower seat with the index finger, so that the bevel of the needle and the scale of the syringe are upward, and the needle is inclined along the vein to make the needle and the skin obliquely penetrate the skin at an angle of 30°. Then, through the vein wall, enter the venous cavity forward at an angle of 5°. After seeing the blood return, the needle will be probed into the spot to avoid the needle slipping out when the blood is collected; but it is not possible to use a deep puncture to avoid hematoma, and immediately remove the cuff. Needle plug can only be pumped out, can not be pushed in, so as to avoid injecting air into the vein to form a gas plug, causing serious consequences. Remove the syringe needle and slowly inject the blood into the anticoagulation tube along the tube wall to prevent hemolysis and foam. Subjects were venously collected and assayed in time for serum separation. 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.
