What is involved in the histamine test?

The

histamine test determines whether a certain substance causes an allergic reaction in the patient's body. Three days before the test, it is recommended to avoid all foods and substances that could cause any symptoms of similar allergies. The patient is then exposed to a small amount of suspicious allergen during the test itself. In the most common form of histamine test, doctors will simply observe the skin area that has been exposed to allergen for any reactions. Patients who prefer more accurate testing may opt for a blood test that measures histamine and allergic antibodies in the system. This involves holding outside areas that are suspicious to cause an allergic reaction and avoid foods such as cheese that can cause similar, albeit non -allergic reactions such as swelling. The patient is also advised to stop taking any antihistamine drugs before the histamine test. If the patient complains of chronic allergies, it is also recommended to collect MalFood samples that eat during these periods. Food samples can be used to determine specific allergens during testing.

After the preparation time, the patient often undergoes one of two tests, the most common of which is a skin test. The skin test includes the designation of a specific area on the patient's skin and slightly scratched the needle to break the highest layer. A small amount of suspicious allergen is introduced into the broken skin. If the distinctive area begins to increase, itching or turns red, it is highly likely that the patient was allergic to the substance. If no reaction is observed, the patient may decide that the allergen will injure directly below the highest layer of skin to confirm the results of histamine test.

Although the skin test is the most popular histamine test, it is considered to be a lower blood test method. While a skin test can determine whether a particular substance is an allergen, cannot confirmThe degree of allergic patient. The blood test in which the blood sample is examined to histamine levels can measure the degree of allergic reaction and exclude the factors of changing results such as sensitive skin. The results of the histomine test in the blood can also be used to determine whether the patient's tolerance improves to allergen.
