What are the five categories included in the whole blood examination

Whole blood five category examination usually includes five basic indicators: white blood cell count, red blood cell count, hemoglobin concentration, platelet count, and hematocrit, as well as analysis of white blood cell subsets such as neutrophils and lymphocytes. The main testing items include white blood cell five classification count, red blood cell related parameters, platelet volume distribution, etc.

1. Five classification of white blood cells:

divides white blood cells into neutrophils, lymphocytes, monocytes, eosinophils, and basophils through laser scattering technology. Elevated neutrophils are commonly seen in bacterial infections, while increased lymphocytes may be associated with viral infections. Abnormal eosinophils indicate allergies or parasitic infections. The instrument can detect the absolute value and percentage of various types of cells.

2. Red blood cell parameters:

includes three basic data: red blood cell count, hemoglobin concentration, and hematocrit. At the same time, derivative indicators such as average red blood cell volume and average hemoglobin content are measured. These parameters can effectively screen for anemia types, such as small cell anemia commonly associated with iron deficiency, and large cell anemia often associated with vitamin B12 deficiency.

3. Platelet detection: In addition to platelet count,

also analyzes parameters such as platelet volume distribution width and average platelet volume. Thrombocytopenia may indicate hematopoietic dysfunction, and volume enlargement is common in myeloproliferative disorders. Dynamic monitoring has important value in assessing bleeding risk.

4. reticulocytes:

Some high-end instruments can detect the proportion of immature reticulocytes, reflecting the activity level of bone marrow hematopoietic function. This indicator has special significance for evaluating the treatment effect of anemia and early diagnosis of hematopoietic system diseases. Elevated values are commonly seen in hemolytic anemia or the recovery period after bleeding.

3. Abnormal cell prompt:

five classification technology can identify abnormal cells in peripheral blood, such as primitive cells, atypical lymphocytes, etc. These findings may indicate hematological disorders that require further diagnosis through bone marrow aspiration. Some instruments can also detect nucleated red blood cells, which is helpful for the diagnosis of hemolytic disease of the newborn. Before the physical examination, fasting should be maintained for 8-12 hours to avoid vigorous exercise affecting the accuracy of the results. Women's menstrual period may interfere with platelet testing, and it is recommended to avoid physiological examinations. Long term use of aspirin and other medications requires prior notification to maintain a balanced diet and to supplement foods rich in iron and folate, such as lean meat and green leafy vegetables, to help maintain normal blood indicators. Regular whole blood tests can detect early abnormalities in the blood system. It is recommended that healthy individuals undergo an annual check-up, and chronic disease patients follow medical advice to increase the frequency of testing.
