The blood test for hemorrhagic fever should look at neutrophils, platelets, and allogeneic lymphocytes.
1. Neutrophils: If the hemorrhagic fever is in the early stage, the cells are active, at this time the neutrophils will appear high, however, in the later stage of the disease is in a stable condition, the neutrophils will not show changes, and it is possible that the value will also be reduced.
2. Platelets: In the late stage of the disease, there is usually a decrease in platelets, which is also accompanied by hemorrhage at this moment, and it is necessary to do bone marrow aspiration in time for examination.
3. Heterophilic lymphocytes: Heterophilic lymphocytosis with fever is considered to be an infection, and this heterophilic lymphocytosis in the peripheral blood smear, if combined with thrombocytopenia, is instructive in the diagnosis of hemorrhagic fever.
Most of the patients with epidemic hemorrhagic fever also have sudden chills and fever, and their body temperature rises to 39~40 degrees within 1~2 days, and the fever type is mainly flaccid fever and episodic fever, and they also have headache, severe back pain, orbital pain, etc. If the above symptoms occur, they should go to the hospital in time, and complete the relevant examinations under the direction of the doctor to standardize the treatment.
