Low percentage of lymphocytes and high percentage of neutrophils, consider the possibility of viral infection, it is recommended to recheck the blood routine after some time. If there are no other symptoms, you can ignore it, there is no big problem, don’t worry too much, just take anti-viral and anti-infection drugs. In fact, the most detailed judgment should be made in conjunction with the total number of white blood cells. If the total is high, the high neutrophil ratio is also relative and is caused by elevated lymphocytes. If the total white blood cell count is normal or low, it is caused by a decrease in neutrophils. An increased lymphocyte ratio is most commonly seen in viral infections, bacterial infections that increase neutrophils, and also in immune system disorders. If you feel that there are other symptoms of discomfort, it is recommended to go to the hospital for a detailed review before making a judgment.
