Blood cell analysis with five classifications is mainly used to aid in the diagnosis of infections, allergies, anemia, and blood system disorders.
Blood cell analysis is a test that detects the amount and relative proportion of various cells in the blood. There are mainly white blood cell count, neutrophil percentage and ratio, lymphocyte percentage and ratio, red blood cell count, hemoglobin content, platelet count and so on.
1. Neutrophils: Bacterial infections can lead to an increase in neutrophil ratio. In addition, malignant hematologic diseases, such as acute leukemia, can also show an increase in neutrophils in routine blood tests.
2. Lymphocytes: viral infections can lead to a decrease in the lymphocyte ratio. Chronic lymphocytic leukemia, etc. will show an increase in the number and percentage of lymphocytes.
3. Eosinophils: Increased eosinophils are usually indicative of allergic or parasitic infections.
4. Erythrocytes are elevated in cases of dehydration or true erythrocytosis, and decreased in cases of anemia and malnutrition.
5. Platelet counts usually range from (100-300) x 10^9/L, with a low count indicating a risk of spontaneous bleeding, as seen in primary immune thrombocytopenia, and a high count indicating a risk of thrombosis, as seen in primary thrombocythemia. Some patients may also have transient thrombocytopenia after a viral infection.
If the patient finds that the blood cell analysis is abnormal, it is necessary to go to the hospital in a timely manner, under the guidance of the physician to clarify the diagnosis.
