specific IgE antibody

IgE is mainly derived from the plasma cells in the respiratory tract and the submucosal mucosa. It is a kind of cytopathic antibody and is associated with allergies, parasitic diseases and skin allergies. Another type of IgE that specifically binds to an allergen, called specific IgE, is highly specific and sensitive to the diagnosis of allergic asthma, and is important for finding allergens. Basic Information Specialist classification: Respiratory examination classification: immune examination Applicable gender: whether men and women apply fasting: fasting Tips: Before the check: Taboo: Patients taking anti-allergic drugs and some cold medicines containing anti-allergic ingredients will affect the test results. Normal value The normal value of serum immunoglobulin E (IgE) is 0.1-0.9 mg/L. Total IgE is strongly positive and specific IgE is negative. Clinical significance Abnormal results: Allergen-specific IgE levels in serum can only indicate the individual's sensitivity to the measured allergen. However, it is not possible to rely solely on the detection of allergen-specific IgE levels in serum, but must be combined with clinical history and other diagnostic methods to confirm allergies. People who need to be examined: The patient is an allergic constitution and is not sensitive to allergen-specific tests. High results may be diseases: small intestinal allergic purpura, pediatric Echo and Coxsackie virus infection, pediatric high immunoglobulin E syndrome, pediatric visceral larval migration, hand, foot and mouth disease, senile asthma, fungal allergic asthma, occupation Sexual Asthma Considerations Pre-examination contraindications: Patients taking anti-allergic drugs and certain cold medicines containing anti-allergic ingredients will affect the test results. It is recommended to stop the drug for at least two days before the in vitro test for allergic reactions. Requirements for examination: Desensitization is recommended for patients with a specific IgE test that is positive (++) or higher. Serum samples contaminated with microbes, heat treated, and containing significant particles should not be used for testing. Severe hemolyzed serum or lipemia serum should be avoided. Inspection process A serum sample was taken. Serum samples contaminated with microbes, heat treated, and containing significant particles should not be used for testing. Severe hemolyzed serum or lipemia serum should be avoided. Not suitable for the crowd Inappropriate people: There are no clear requirements. Adverse reactions and risks There are no related complications and hazards.
