What is the purpose of the RAST test?
A wide range of allergies can be tested using the Radioallergosorbent Test(RAST) or its equivalent tests. The goal of these tests is to find and measure different antibodies (Immunoglobulin E) for some of the common allergens.
- Environmental Allergens:
Seasonal allergies like fevers can be caused by pollen from trees grass and greenery outside
Dust mites from tiny organisms inside the house can cause allergies
Waste from household pets like dogs and cats can cause allergies
Molds that grow in some environments can cause allergies. - Food Allergens:
People are allergic to different foods
The most common and severe food allergen is found in peanuts
Tree nuts such as almonds, cashews, and walnuts can also cause allergies.
Some people*- are allergic to seafood like crab, lobster, shrimp and many more.
Eggs and egg products can also cause allergies in some people.
Milk allergies are most common in children. - Insect venom:
Allergic reactions to insect stings like bees, wasps and other insects can be tested through the RAST test - Medications:
Allergic reactions to certain medications like antibiotics can be found through this test
What is the process for the RAST Test?
- The patient’s blood sample will be collected by a healthcare professional, typically a phlebotomist or nurse. To do this, a needle is typically inserted into a vein, usually in the arm.
- The serum, which is the clear liquid portion of blood, is isolated by processing the collected blood sample. The presence of antibodies, including Immunoglobulin E (IgE) in serum, is an important factor in allergy testing.
- Selection of allergen extracts: Specific allergens that are suspected of causing allergic reactions in the patient are selected. Pollen, dust mites, specific foods, or other potential triggers are among the allergens that could be present. Extracts of these allergens are prepared for testing.
- Incubation involves mixing the patient’s serum with the allergen extracts in a laboratory setting. If the patient has IgE antibodies in their serum that react with these allergens, they will bind together.
- The level of IgE antibodies bound to the allergens will be measured by the laboratory technicians. In the case of the RAST test, this measurement often involved the use of radioisotope-labeled antigens that could bind to IgE antibodies, making it possible to quantify the bound antibodies.
When should one get a rast test?
Taking the RAST test is advised if you are experiencing the following problems
- Allergy Symptoms: If you are experiencing common allergy symptoms such as sneezing, runny or stuffy nose, itchy or watery eyes, skin rashes, hives, wheezing, coughing, or difficulty breathing, and you suspect that these symptoms may be due to allergies, it may be a good time to consider an allergy test.
Unexplained Symptoms: Sometimes, individuals may have symptoms that are difficult to attribute to a specific allergen. In cases where the cause of the symptoms is unclear, an allergy test can help identify potential allergens. - Severe Allergic Reactions: If you have a history of severe allergic reactions (anaphylaxis) to certain foods, insect stings, medications, or other substances, an allergy test can help confirm the specific allergen that triggers these reactions. This information is crucial for managing and avoiding potential life-threatening situations.
- Chronic or Recurrent Symptoms: Chronic or recurring allergy symptoms that affect your quality of life may warrant allergy testing to identify the underlying triggers and develop an effective treatment plan.
- Before Immunotherapy: If you are considering allergen immunotherapy (allergy shots) as a treatment for your allergies, your allergist may recommend allergy testing to determine the specific allergens to include in the treatment.
- Food Allergies: In cases of suspected food allergies, especially if you have experienced adverse reactions after consuming certain foods, allergy testing can help confirm the presence of food allergies and identify the specific allergenic foods.
- Environmental Allergens: If you suspect that environmental factors, such as pollen, dust mites, or mould, are causing your allergy symptoms, testing can help pinpoint these allergens.
