Basic Information Specialist classification: growth and development examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Tips: Do not eat too greasy, high-protein foods the day before, and avoid heavy drinking. Normal value The red blood cell count is 5.66 (normal value 3.5-5.5). Clinical significance Abnormal result Low red blood cell count: common in blood loss, anemia, hemorrhage, bone marrow hematopoietic disorders, erythropoietin deficiency, transfusion reaction, leukemia, multiple myeloma, malnutrition, etc. Low white blood cell count: common in bone marrow hematopoietic disorders, cytotoxic reactions, autoimmune diseases, liver and spleen diseases, radiation sickness. High white blood cell count: It is a symptom of infectious disease, inflammatory disease, leukemia, mental illness, and connective tissue damage. High red blood cell count: Possible conditions are hypoxemia, congenital heart disease, pulmonary heart disease, pulmonary fibrosis, splenomegaly, dehydration, and increased erythropoietin caused by nephropathy Low red blood cell volume: common in blood loss, anemia, rheumatism, bone marrow hematopoietic disorders, erythropoietin deficiency, transfusion reaction, leukemia, multiple myeloma, malnutrition, etc. High red blood cell volume: dehydration, burns, diarrhea, convulsions, polycythemia, splenomegaly, and symptoms in shock. Low hemoglobin: May have anemia. People who need to be checked There are people who are weak and weak, sleepy, pale skin, mucous membranes, palpitations, dizziness, headache, tinnitus, vertigo, inattention, and lethargy. Low results may be diseases: congenital heart disease, Alzheimer's disease results are high, possible diseases: dementia syndrome considerations Taboo before the test: Do not eat too greasy, high-protein foods the day before the test, to avoid heavy drinking.

Requirements for examination: When taking blood, you should relax your mind to avoid the contraction of blood vessels caused by fear and increase the difficulty of blood collection. Inspection process Preparation of cell suspension For suspension cultured cells, proceed directly to step 2 below (counting and calculation process). If the counting object is an adherently growing cell, the culture is first prepared as a cell suspension. 1. The culture was terminated, the culture solution was aspirated, and the culture was washed once with PBS. 2. Add 1 ml of 0.25% trypsin solution to the flask and digest at 37 ° C for 3 to 5 minutes. During the period, it is constantly observed under the microscope. When the cells become round and close to the wall, the digestive juice is discarded. 3. Add a certain amount of culture solution (if these culture cells are no longer useful, add PBS), blow with a pipette, and let the cells detach from the wall to make a cell suspension. Not suitable for the crowd Newborn. Adverse reactions and risks Hemophilia and diffuse intravascular coagulation.
