The routine blood manifestations of Erythropoietic Disease mainly include increased erythrocyte count, increased erythrocyte specific volume, elevated hemoglobin, and increased white blood cell count. 1. Increased erythrocyte count: the erythrocyte count of patients with this disease can be increased, usually up to (6-10) × 10^12/L. The erythrocyte count of patients with this disease can be increased. 2. Increased erythrocyte specific volume: the erythrocyte specific volume is increased in patients with this disease, and most of them can reach about 0.6-0.8. 3. Elevated hemoglobin: hemoglobin is elevated in patients with this disease, up to 170-240g/L. 4. Leukocytosis: In patients with Erythrocytosis, the leukocyte count is increased up to (10-30)×10^9/L, and there is usually a leftward shift of the nucleus. If the blood count of Erythrocytosis is present, it is recommended that the patient receive timely treatment to relieve symptoms and avoid thrombosis.
