Blood Tests – False Positive?

Freedom Allergy, Allergy Doctor, Atlanta, Georgia

False Positive Food Allergies

While many medical offices use blood tests to evaluate allergies, board certified allergists rely on skin prick testing, which offers a more appropriate reflection of true allergies. Blood tests frequently show “false positive” results, and provide evidence of an allergy that is not accurate. Many times, families come to our office with blood results from another doctor’s office showing a food allergy, when they have never actually had an allergic reaction to that food. If you have a question of blood results, it would be best to discuss the findings with an allergist, to make sure you move forward with the best plan for your allergies. After all, why eliminate a food from your diet, when you are not actually allergic to that food?

Fall Allergies Are Upon Us

Freedom Allergy, Fall Allergies Ragweed, Atlanta, Georgia

Autumn is rapidly approaching. As backpacks fill with homework, football games kick off, and the Georgia heat simmers down, many know ragweed season also lurks around the corner. Ragweed grows most predominantly in the southern, northeastern and midwestern United States, and thrives in warm, humid environments. According to the Asthma and Allergy Foundation of America, 75% of people who are allergic to pollen-producing plants also suffer ragweed allergies. Ragweed emits a particularly large amount of pollen – up to 1 billion pollen grains per plant – and the pollen can extend up to two miles into the atmosphere. Ten to twenty percent of Americans suffer ragweed allergy flare-ups near the end of the summer, usually peaking around early September, and these flare-ups can lead to asthma exacerbations, headaches, and chronic sinusitis. With fall allergy season already upon us, do not wait to schedule an appointment with your board certified allergist, who can help keep your allergies and asthma under control.

Why Choose an Allergist for your Allergy and Asthma?

Allergies and asthma are both chronic conditions, and warrant visiting a specialist for the best management. However, with so many specialists out there, how do you know which one to choose?  Read the FAQ below.

My allergies bother my ears, nose and throat – doesn’t this mean I should see an ear, nose and throat doctor?

Many times, patients go directly to an ear, nose and throat (ENT) doctor for their allergy symptoms. After all, don’t allergies bother your ears, nose and throat?

Ear, Nose and Throat doctors are surgeons who specialize mainly in structural problems that can be corrected with surgery. But many of these problems, such as difficulty breathing through the nose, or having a raspy voice or having trouble hearing, are actually due to allergies.  Allergies, eczema, and asthma are all chronic conditions that fall under the same umbrella of allergy medicine, and more than 50% of sinus problems are caused by allergies.  The other 50% are often caused by a combination of both allergy and non-allergy related problems.

Food Allergy

Food Allergy – Atlanta, Peachtree City, Georgia

What is a Food Allergy?

A food allergy occurs when your body’s immune system overreacts to a protein in a certain food. In severe allergies, these reactions can be life threatening. The majority (90 percent) of food allergies are caused by eight foods: cow’s milk, eggs, fish, peanuts, shellfish, soy, tree nuts, and wheat.

Food Allergy Versus Food Intolerance

Reacting to a food does not necessarily mean you are allergic to that food – you may just be intolerant to it. Food intolerance can cause similar symptoms to a food allergy, but food intolerance does not cause a full immune system response in your body. Food allergies cause an immune system response, and affect multiple organs. Generally, food intolerance causes less severe reactions, and may only cause digestive problems. People develop food intolerance for many different reasons, including lacking an enzyme necessary to digest the food, or having a sensitivity to additives in a food.

Ways to Diagnose a Food Allergy

  1. Skin Testing

During allergy skin testing, your skin is exposed to several allergens (food and/or environmental) and assessed for an allergic response. Your allergist will use a small plastic device to prick the skin and apply the allergens. If your skin becomes red, raised and itchy after 15-20 minutes, this may indicate an allergy.

  1. Allergy Blood Testing

Allergy blood tests are used if a patient can’t stop a medication that interferes with skin testing, if the patient has a skin condition like dermatitis, psoriasis or eczema, or if it would better suit the patient to have just one “poke” versus several (ie, a baby or young child). Blood testing is also used if the patient has poorly controlled asthma, or if the allergy is so severe that the testing could cause a systemic or anaphylactic reaction. Allergy blood tests are also used to check how well a patient’s allergy treatment is working.

Types of allergy blood tests include Enzyme-Linked Immunosorbent Assay (ELISA) and Radioallergosorbent Test (RAST). ELISA is used more commonly than RAST, and measures the amount of antibodies in your blood specific to certain allergens.

Complement testing can be used to measure the amount of a specific antibody or a specific antigen in the blood. The test helps determine which foods may be causing inflammation in the body and triggering an immune response.

  1. Oral Food Challenge

Double-blinded, placebo-controlled oral food challenge is considered the “gold standard” for food allergy diagnosis. This test is often used after skin prick testing and allergy blood testing fail to provide definitive results. In an oral food challenge, the patient is given very small amounts of a food that is suspicious for an allergy. Over a certain length of time, the amount of food is increased until any sign of an allergic reaction occurs. This test is always done under strict supervision of an allergist. The oral food challenge procedure can be costly and time consuming, however, so it is often not performed.

Delayed Food Allergy

Food allergy symptoms typically occur right after ingesting the responsible food, or at least within two hours. However, in a delayed response, the symptoms may take six or more hours to appear. These delayed responses can surface in different ways – such as a skin reaction from a food allergy, or a gastrointestinal reaction after ingesting milk or soy.

 

Patch Testing

Patch Testing is a way to test for the allergens responsible for delayed allergic reactions. Instead of poking the skin with a plastic device to administer an allergen (as in allergy skin testing), patch testing occurs by placing a patch on a patient’s back that contains a small amount of the allergen. The patch stays on for two days, since a delayed allergic response will not occur quickly enough for skin prick testing. The patch site will be observed for redness, blisters, and swelling.

 

Sensitivity Testing

Sensitivity Testing is a blood test used to check for food sensitivities (different from food allergies). Food sensitivity is different from food allergy and food intolerance, and essentially describes an inconsistent and unpredictable reaction to certain foods. A person with food sensitivity may eat the food one time with no reaction, but experience symptoms (stomach cramps, nausea, acid reflux) at other times.
