Low white blood cells cannot be supplemented with food and need to be improved quickly by taking medications that elevate white blood cells, such as vitamin B4, Ricodin, and human granulocyte stimulating factor.
In adults, leukopenia is indicated by a blood leukocyte count of less than 4.0 x 10⁹ /L.
Pathologic causes of leukopenia include viral infections, typhoid fever, malaria, oncologic chemotherapy, aplastic anemia, myelodysplastic syndromes, and autoimmune diseases.
If low leukocytes are present, the number of leukocytes can be raised by taking drugs that raise leukocytes, such as vitamin B4, Lycopodium, shark liver alcohol, and human granulocyte stimulating factor.
However, it is worth noting that there are many causes of low white blood cells, and it is necessary to consult a doctor to identify the cause and treat the cause of low white blood cells, such as treating systemic lupus erythematosus with prednisone, in order to raise the white blood cells in the peripheral blood fundamentally. The medication needs to be taken and used under the guidance of a doctor or pharmacist.
