eosinophil count

According to the total number and classification of white blood cells (eosophilic granulocytes only account for 0.5% to 5% of the white blood cell classification count). Reduced in adrenal hyperfunction, aplastic anemia, acute myocardial infarction, severe burns, major surgery, severe disease such as lobar pneumonia, typhoid fever and scarlet fever. Basic Information Specialist classification: growth and development examination classification: blood examination Applicable gender: whether men and women apply fasting: fasting Tips: After taking blood, you need to press it at the pinhole for 3-5 minutes to stop bleeding. Normal value Blood cell automatic counter (50 ~ 300) × 106 / L (50 ~ 300 / mm3). Clinical significance (1) eosinophilia 1 allergic diseases, bronchial asthma, urticaria, nodular polyarteritis, drug allergy, serum disease, etc. 2 cutaneous pemphigus, herpetic dermatitis, pruritus, pleomorphic exudative erythema, eczema, etc. 3 parasitic diseases ascariasis, hookworm disease, schistosomiasis, paragonimiasis, cysticercosis, etc. 4 Infectious scarlet fever, measles latency, Löffler syndrome, infectious disease recovery period, etc. 5 blood diseases eosinophilic leukemia, chronic myeloid leukemia, Hodgkin's disease, pernicious anemia, familial eosinophilia, tropical and non-tropical eosinophilia, myelofibrosis, organs Transplant rejection, etc. 6 other radiation exposure, ovarian tumors, sarcoidosis, adrenal insufficiency and so on. (2) eosinophilia 1 infection with typhoid, paratyphoid, application of glucocorticoids and so on. 2 drugs after ACTH, adrenocortical hormone and so on. 3 stress state. Low results may be diseases: high aplastic anemia results may be diseases: parasitic diseases precautions First, the precautions before blood draw 1, do not eat too greasy, high-protein food the day before the blood, to avoid heavy drinking. The alcohol content in the blood directly affects the test results. 2. After 8 pm on the day before the physical examination, fasting should be done to avoid affecting the detection of indicators such as blood glucose in the second sky. 3, should relax when taking blood, to avoid the contraction of blood vessels caused by fear, increase the difficulty of blood collection. Guests with a history of fainting should explain in advance and we will make special arrangements. Second, should pay attention after blood draw 1. After blood is drawn, local compression is required at the pinhole for 3-5 minutes to stop bleeding. Note: Do not rub, so as not to cause subcutaneous hematoma. 2, the pressing time should be sufficient. There is a difference in clotting time for each person, and some people need a little longer to clotting. Therefore, when the surface of the skin appears to be bleeding, the compression is stopped immediately, and the blood may be infiltrated into the skin due to incomplete hemostasis. Therefore, the compression time is longer to completely stop bleeding. If there is a tendency to bleed, the compression time should be extended. 3, after the blood draw symptoms of fainting such as: dizziness, vertigo, fatigue, etc. should immediately lie down, drink a small amount of syrup, and then undergo a physical examination after the symptoms are relieved. 4. If there is localized congestion, use a warm towel after 24 hours to promote absorption. Inspection process (1) Take a small drop of blood on one end of the slide, and use a push piece to push the circumference around 35 ° ~ 45 ° to leave a proper amount of voids, which can distinguish the thin blood of the head, body and tail. The length of the blood film is not less than 2.5 cm, and the remaining space to the other end of the slide is about 1 cm. The blood film is dried and stained. (2) Wright's Giemsa composite staining method: flat blood sample on the staining rack, add 3 to 5 drops of staining solution, immediately cover the blood film, add about 5 to 10 drops of buffer after about 30s, gently shake the glass The tablets or lightly blow the mixture to mix the dye solution with the buffer solution. After 5 to 10 minutes, the dye solution is washed away with water and dried for microscopic examination. (3) Rapid method: place the rapid dyeing liquid A and liquid B in the appropriate size dyeing tank, immerse the blood film in the liquid for 30s, wash it, then immerse it in the liquid for 30s, wash it, and dry it for microscopic examination. (4) Microscopic examination: Select the junction of the meninges and tails, and the red blood cells have not overlapped with oil mirrors. The examination should have a certain direction from top to bottom and left and right, and take into account the edges of both sides of the long film of the blood film, otherwise it will affect various cells. Detection rate. Count 100 to 200 white blood cells, classify them according to their morphology, and find the percentage. Not suitable for the crowd Have a coagulopathy such as hemophilia. Adverse reactions and risks Risk of infection: If you use an unclean needle, you may be at risk of infection.
