What Is a Blood Count?
No abnormal number of red blood cells and white blood cells.
- A full blood count is a screening test, and it is needed for many diseases to diagnose it. Through this test, doctors can observe the increase, decrease, and destruction of blood cells, and learn about many conditions such as inflammation, allergies, and blood clotting, which are extremely important for the diagnosis and treatment of diseases.

- No abnormal number of red blood cells and white blood cells.
Clinical significance of whole blood cell count
- Abnormal results: Low red blood cell count: common in blood loss, anemia, bleeding, bone marrow hematopoietic disorders, erythropoietin deficiency, blood transfusion reactions, leukemia, multiple myeloma, malnutrition, etc. Low white blood cell count: common in hematopoietic disorders of bone marrow, cytotoxic reactions, autoimmune diseases, liver and spleen diseases, radiation diseases. High white blood cell count: symptoms of infectious disease, inflammatory disease, leukemia, mental illness, connective tissue damage. High red blood cell count: Possible conditions are hypoxemia, congenital heart disease, pulmonary heart disease, pulmonary fibrosis, splenomegaly red blood cell dehydration, and high erythropoietin caused by kidney disease. Low red blood cell volume: common in blood loss, anemia, rheumatism, bone marrow hematopoietic disorders, lack of erythropoietin, blood transfusion reactions, leukemia, multiple myeloma, malnutrition, etc. High red blood cell volume: symptoms of dehydration, burns, diarrhea, convulsions, erythrocytosis, splenomegaly, and shock. Hypochrome: May have anemia. People to be checked: People with weakness, fatigue, drowsiness, pale skin and mucous membranes, palpitations, dizziness, headache, tinnitus, dizziness, inattention, and lethargy.
Full blood cell count considerations
- Unsuitable population: newborns. Contraindications before the test: Do not eat too greasy, high-protein food the day before the test, and avoid drinking a lot. The alcohol content in the blood directly affects the test results. After 8 pm the day before the physical examination, you should fast. Requirements during the examination: You should relax when taking blood to avoid contraction of blood vessels due to fear and increase the difficulty of collecting blood.
Whole blood count check process
- (1) Preparation of cell suspension For cells cultured in suspension, you can directly perform the following step 2 (counting and calculation process). If the object to be counted is adherent cells, the culture must first be prepared as a cell suspension. Stop the culture, aspirate the culture solution, and wash the culture once with PBS. Add 1ml of 0.25% trypsin solution to the culture flask and digest at 37 ° C for 3-5min. During the observation under the microscope. When the cells are rounded and near the wall, the digestive juice is discarded. Add a certain amount of culture solution (if these cultured cells are no longer useful, add PBS), blow with a pipette, and remove the cells to make a cell suspension. (2) Counting and calculation process Place a cover slip dedicated to counting in the center of the cell counting plate. Aspirate the cells with a glass siphon, and let the siphon flow out of the suspension on the cover glass or on the bottom of the counting plate, until the cover glass is filled with liquid. Count the total number of cells in a large square with a microscope under a microscope.
