Patients with elevated white blood cells and platelets in the acute phase, accompanied by symptoms of chills and chills, are usually considered to have abnormal white blood cells and platelets caused by infectious diseases most commonly. If the patient has coughing and sputum symptoms, check for pulmonary disease and respiratory tract infection. If the patient has abdominal pain and diarrhea, further improvement of the intestinal tract and stool examination is needed to clarify whether there is an intestinal infection. If the patient has a recent skin injury, he or she should be alerted to the presence of skin infection or even sepsis secondary to skin infection. If the patient does not find a clear infectious agent or foci of infection through the examination, and at the same time the patient has enlarged liver and spleen, or even pressure pain behind the sternum and coagulation dysfunction, in this case, the patient also needs to be alerted to whether the patient has hematologic diseases, resulting in elevated white blood cells and platelets, and can further improve the bone marrow aspiration examination, and take bone marrow biopsy pictures to clarify the cause for further treatment. The cause of the disease can be clarified and further treatment can be done.
