Total IgE greater than 600 KU/L is classified as a Class VI allergy. IgE refers to a secretory immunoglobulin, and the amount of IgE synthesized suggests that the body may be suffering from allergic diseases. The lgE test evaluation criteria are divided into grade 0 (<0.35KU/L), grade 1 (≥0.35 KU/L and <0.7KU/L), grade 2 (≥0.7 KU/L and <3.5KU/L), grade 3 (≥3.5KU/L and <17.5KU/L). Grade 4 (≥17.5 KU/L and <50 KU/L), grade 5 (≥50 KU/L and <100 KU/L), and grade 6 (≥100 KU/L), so total IgE greater than 600 KU/L is a grade 6 allergy. It often suggests that the patient is in the midst of an allergic disease, such as allergic urticaria, allergic rhinitis, and allergic asthma. When allergy symptoms are severe, oral treatment with drugs such as loratadine tablets and levocetirizine hydrochloride tablets can help relieve allergy symptoms. In addition, it is necessary to observe whether there are complications caused by allergy, such as bronchial asthma, dermatitis, etc. Once appeared, it is also necessary to treat the complications, and glucocorticoid drugs can be used to alleviate the symptoms, such as budesonide inhalation powder aerosol, beclomethasone propionate cream, dexamethasone tablets and other drugs. After the allergic symptoms are relieved, it is necessary to carry out the investigation of allergic substances, and after clarifying the allergens, it is necessary to avoid contact with the substances again, as well as to avoid eating foods that have been clarified as allergens.
