Small white blood cells are usually lymphocytes; large white blood cells are usually granulocytes and monocytes, with neutrophils predominating. Increased percentage of lymphocytes and decreased percentage of neutrophils can be seen in infectious diseases and hematologic diseases, which need to be judged in combination with other symptoms and signs.

Infectious diseases: can be seen in viral infections (influenza, chickenpox, rubella, etc.), gram-negative bacterial infections (typhoid fever, paratyphoid fever, etc.), most often accompanied by fever, chills, malaise, etc., and it is recommended that anti-infective treatments are carried out reasonably under the guidance of the doctor, such as acyclovir anti-viral treatment for viral infections.
2. Blood system diseases: it can be seen in lymphoma, aplastic anemia and so on. If it is a blood system disease, in addition to the abnormal white blood cell ratio, it will be accompanied by abnormal absolute white blood cell value, it is recommended to consult the hematology department, improve the imaging, bone penetration and other related examinations for comprehensive assessment.
