Points to note before testing

•  It is not required to fast prior testing, while it is crucial to maintain the usual dietary habits, consume a variety of food where possible. Testing IgG or IgA reflects the delayed reactions to foods that consumed in the past 3 months, while testing IgE reflects the immediate reactions to foods that consumed in the past 48 hours. In order to reduce the risk of fatality, it is strongly advised to avoid any foods that may cause potential adverse reactions or anaphylaxis prior testing.
•  Immunosuppressive drugs, such as oral and intravenous corticosteroids (e.g. prednisone, beclomethasone, fluticasone, triamcinolone) may affect the test results. It is suggested to abstain from these medications for 3 weeks before taking sample. For clients who need regular medications, please consult your doctor before taking the test.
• Test client who has been suffering from bleeding disorders (e.g. coagulation factor deficient, Von Willebrand disease or hemophilia) is not suggested to take this test. It is at healthcare professional’s discretion based on the test client’s medical history.
