High neutrophil count can be seen in physiological high, such as late pregnancy, childbirth, after labor, etc. It can also be seen in pathological high, such as acute infection, serious tissue injury, acute hemorrhage, etc. It is recommended to consult a specialist. 1. Physiological high: normal neutrophils are higher in the afternoon than in the morning. In addition, temporary highs may occur in the late stage of pregnancy, after strenuous exercise, after a full meal, after a shower, after high temperature or severe cold, and can be reduced to normal after removing the causes. 2. Pathologically high: acute infections with purulent cocci infections are the most common, such as Staphylococcus aureus, Streptococcus pneumoniae, etc., but some very serious infections may not be high or even lower; severe trauma, extensive burns, acute myocardial infarction, etc. or acute hemorrhage within 1-2 days after the neutrophils may be high. Metabolic poisoning such as uremia, acute chemical poisoning such as acute lead poisoning, etc., biological toxins such as snake venom, etc., can appear high neutrophils; there are also certain malignant tumors such as leukemia, hepatocellular carcinoma, gastric cancer, etc., can also appear high neutrophils. If the neutrophil count is high, it is recommended to check the cause in time and take active treatment.
