What Is Allergy Testing

Allergy Testing: What to Expect

Healthcare providers perform allergy tests to determine whether your immune system overreacts to certain substances . If you have an allergic reaction, it means you have an allergy.

People can be allergic to things in the environment like mold, pollen and pet dander. Some people have allergic reactions to bee stings or latex. People with food allergies may not be able to tolerate peanuts, milk or soy.

What Happens During An Allergy Test

If your doctor thinks you might have an allergy, youll probably go see an allergist for testing.

Here’s what to expect. The allergist will ask questions like:

  • What symptoms do you notice when you have a reaction?
  • How often does the reaction happen?
  • How long does it take between eating a particular food and the start of the symptoms?
  • Do any family members have allergies or conditions like eczema and asthma?

The allergist will also do tests. Skin tests are a common way to diagnose allergies.

What Happens During The Rast

  • You will have blood drawn at the lab. The amount needed will depend upon the number of foods being tested for.
  • The lab will send your blood sample out to be tested. Your allergist will call you to discuss the results as soon as they are available, usually in about two weeks.
  • The Food Allergy Clinic uses a specific type of RAST called ImmunoCAP, which has been studied more than others for its use in food allergy. ImmunoCAP allows Food Allergy Clinic allergists to compare your test results with known values and ranges that show the relative likelihood of a food allergy, which can help your allergist make a diagnosis.

What Happens During The Spt

  • First, we place a drop of liquid extract containing a small amount of the suspected food allergen on your forearm.
  • Then, with a device similar to a plastic toothpick, we gently scratch the skin so that a tiny amount of the extract is absorbed.
  • Over the next 10 to 20 minutes, we monitor the skin for a localized reactionredness, swelling or a measurable bump, called a wheal.
  • Afterwards, we wipe off the skin and apply or administer antihistamine as needed. There is no bleeding, so you won’t need a bandage. SPT can be mildly uncomfortable for some people, but the discomfort is usually brief.

When You Need Them And When You Dont

Allergy tests may help find allergies to things you eat, touch, or breathe in. They are usually skin or blood tests.

However, allergy tests alone are generally not enough. It is important to have a doctors exam and medical history first to help diagnose allergies. If the exam and medical history point to allergies, allergy tests may help find what you are allergic to. But if you dont have symptoms and you havent had a medical exam that points to an allergy, you should think twice about allergy testing. Heres why:

How Do Doctors Diagnose Allergies

Doctors diagnose allergies in three steps:

  • Personal and medical history. Your doctor will ask you questions to get a complete understanding of your symptoms and their possible causes. Bring your notes to help jog your memory. Be ready to answer questions about your family history, the kinds of medicines you take, and your lifestyle at home, school and work.
  • Physical exam. If your doctor thinks you have an allergy, they will pay close attention to your ears, eyes, nose, throat, chest and skin during the exam. This exam may include a lung function test to detect how well you exhale air from your lungs. You may also need an X-ray of your lungs or sinuses.
  • Tests to determine your allergens. Your doctor may do a skin test, patch test or blood test. No one test alone is able to diagnose an allergy. Test results are just one of many tools available to assist your doctor in making a diagnosis.

What Is Allergy Skin Testing

The “How To” of Environmental Allergy Testing

Skin testing is the most reliable form of allergy testing. Because mast cells are located in high numbers just under the skin, results of skin testing have proven to be more accurate than blood testing in diagnosing allergies.

Please bring with you a complete list of all medications, as well as your pharmacy number and street address. We routinely send prescriptions electronically and need your pharmacy information to ensure accuracy.

Your initial visit will take 2-3 hours in total. During the testing process, we will use a marking pen on your back and arms, which may cause staining on a shirt. For this reason, we suggest you bring an older shirt with you to wear home.

How Is It Used

The allergen-specific IgE antibody test is a blood test used to help diagnose an allergy to a specific substance or substances for a person who presents with acute or chronic allergy-like symptoms. This is especially true if symptoms are recurrent and appear to be tied to triggers, such as exposures to particular foods or environments, and if other family members are known to have allergies.

Other types of allergy tests may be performed by exposing a person to different substances under careful medical supervision. The usefulness of these tests, however, can be affected by skin conditions, such as significant dermatitis or eczema, and by medications, such as antihistamines and some antidepressants. With some tests there is also the potential for severe reactions, including, for example, anaphylaxis, which can be life-threatening. In these cases, the allergen-specific IgE antibody test may be ordered as an alternative, as it is performed on a blood sample.

The allergen-specific IgE antibody test may also be performed to monitor immunotherapy or to see if a child has outgrown an allergy. Typically, the healthcare practitioner will interpret the results of the test in comparison with a person’s symptoms and any other allergy tests being performed.

How Much Does A Food Allergy Test Cost

How much is an allergy test? That depends on many factors, such as the type of allergy test, the number of foods tested, and more. So unfortunately thereâs no straightforward answer to this question.

Note that EverlyWellâs Food Sensitivity Test is NOT an allergy test. Allergy testing generally requires medical supervision because the test can trigger allergic reactions that are very severe â and even fatal.

EverlyWellâs Food Sensitivity Test will not tell you what foods youâre allergic to. Instead, it will tell you what foods you may be sensitive to, which can help guide your elimination diet. Food sensitivities can result in a number of very unpleasant symptoms , so discovering what foods youâre sensitive to can put you on a path towards greater well-being.

Benefits And Downsides Of At

As a safety precaution, a number of common allergy tests, such as skin tests, can only be performed in a medical setting. Tests that include direct allergen exposure are not available at home.

At-home testing is an option for allergy tests that use a blood sample, but there are pros and cons of at-home versus in-clinic testing.

Benefits of at-home allergy testing include:

  • Convenience: With the ability to take the test in the comfort of your own home, you can easily find a convenient time for testing on your schedule.
  • Easy to use: At-home tests involve straightforward instructions that make the process simple.
  • Clear pricing: Although you usually have to pay out-of-pocket, the costs of at-home tests are made clear up-front.

Downsides to at-home allergy testing include:

An oral challenge test can cause a severe allergic reaction. That’s why this test is only given under close supervision by an allergist.

You may get an allergic reaction during an elimination diet. You should talk to your allergist about how to manage potential reactions.

A skin prick test can bother the skin. If your skin is itchy or irritated after the test, your allergist may prescribe medicine to relieve the symptoms. In rare cases, a skin test can cause a severe reaction. So this test must also be done under close supervision by an allergist.

There is very little risk to having a blood test. You may have slight pain or bruising at the spot where the needle was put in, but most symptoms go away quickly.

What Do The Results Mean

If the results show that you or your child has a food allergy, the treatment is to avoid the food.

There is no cure for food allergies, but eliminating the food from your diet should prevent allergic reactions.

Avoiding allergy-causing foods can involve carefully reading labels on packaged goods. It also means you need to explain the allergy to anyone who prepares or serves food for you or your child. This includes people like waiters, babysitters, teachers, and cafeteria workers. But even if you are careful, you or your child may be exposed to the food by accident.

If you or your child is at risk for a severe allergic reaction, your allergist will prescribe an epinephrine device you can use if accidentally exposed to the food. You’ll be taught how to inject the device in your or your child’s thigh.

If you have questions about your results and/or how to manage allergic complications, talk to your allergist.

What Will Happen During Allergy Testing

During your test, allergic antibodies will activate skin cells, called mast cells. Mast cells release chemicals, such as histamine, that cause swelling and redness, only in the areas where the allergens have touched your skin. This process usually only takes 15 minutes. The hives usually resolve within 30 minutes to one hour.

What Does The Test Result Mean

An elevated allergen-specific IgE result indicates that the person tested likely has an allergy. However, the amount of specific IgE present does not necessarily predict the potential severity of a reaction. A person’s clinical history and additional medically-supervised allergy tests may be necessary to confirm an allergy diagnosis.

Negative results indicate that a person probably does not have a “true allergy,” an IgE-mediated response to the specific allergens tested.

Results of allergy blood testing must be interpreted with care. False negatives and false positives can occur. Even if an IgE test is negative, there is still a small chance that a person does have an allergy. Similarly, if the specific IgE test is positive, a person may or may not ever have an actual physical allergic reaction when exposed to that substance.

How Old Should My Child Be

If you notice allergy-like symptoms in your little one such as a stuffy nose, sore throat, or watery eyes especially after playing outside or being exposed to a certain product or food you should seek a consultation with one of our board-certified specialists. Food allergies can be especially dangerous and should be diagnosed as soon as possible.

When it comes to deciding if your child need allergy testing, Center for Allergy and Asthma of Georgias own Dr. Eugene Hurwitz explains, I recommend allergy testing should be considered for any child who is suffering from nasal allergies not controlled by medications, recurrent sinus infections, asthma, hives, eczema or possible food allergies to identify a cause of these allergic problems.

While your child can be tested for allergies at any age, most tests are done on children who are six months old or order. Allergy testing has the potential to be wrong for very young patients.

What Do The Results Of An Allergy Test Mean

Allergy test results may be:

  • Negative: You arent allergic to that substance. Its rare to get a false negative allergy test result .
  • Positive: Youre allergic to that substance. Note that even when tests correctly show that you have an allergy, it doesnt necessarily mean that youll react to that allergen. A false positive test result is possible, especially from a blood test. A false positive means the results show you have an allergy when you dont.

What Types Of Tests Do Doctors Use To Diagnose Allergies

Skin Prick Allergy Test

Skin Prick Test

Skin testing can confirm many common types of allergies. In some cases, skin tests can be the most accurate and least expensive way to confirm allergens. For prick/scratch testing, the doctor or nurse places a small drop of the possible allergen on the skin. They will then lightly prick or scratch your skin with a needle through the drop. If you are sensitive to the substance, you will develop redness, swelling and itching at the test site within 15 minutes. You may also see a wheal, or raised, round area, that looks like a hive. Usually, the larger the wheal, the more likely you are to be allergic to the allergen.

It is important to know:

  • A positive skin test result does not by itself diagnose an allergy.
  • A positive skin test does not predict the severity of an allergic reaction.
  • A negative skin test usually means you are not allergic.

Intradermal Skin Test

In intradermal testing, the doctor or nurse injects a tiny amount of allergen into the outer layer of skin. The doctor checks your skin after a set amount of time for results, like with the skin prick test. Doctors may use this test if the skin prick test results are negative but they still suspect you have allergies. A doctor may use this test for diagnosing drug or venom allergy. At this time, there are very few indications for intradermal skin testing for food allergy.
