Allergy Testing Clinic in Webster, TX

Allergies are abnormal reactions of the immune system that occur when an allergen, such as pollen or dust, comes into contact with the immune system. A person with allergies reacts differently to a particular substance than someone who is not allergic, as these substances are typically innocuous and cause no harm to someone without hypersensitivity. Some people have only one type of allergy, but in many cases, people with allergies are allergic to several substances, from certain foods to environmental allergens like dust, pollen, and pet dander. Allergies are the most common type of immune response and are caused by exposure to an allergen. They can affect people of any age and any gender but are more likely to affect people with certain risk factors, including those who smoke.

Symptoms of allergies are known as allergic reactions, which can range from mild to severe. While the symptoms of allergies can vary for each person, the most common symptoms associated with allergies include:

• Sneezing and itchy, stuffy, or runny nose
• Itchy nose, mouth, eyes, or mouth
• Itchy, red, watery, or swollen eyes
• Facial swelling, swollen lips, and tongue (angioedema)
• Itchy skin
• Skin rashes (allergic contact dermatitis, eczema)
• Hives
• Cough
• Wheezing
• Shortness of breath
• Headache
• Nausea and vomiting
• Asthma attack
• Anaphylaxis (a severe allergic reaction)

Untreated allergies may also result in:

• Nasal congestion
• Headache
• Sore throat
• Postnasal drip
• Decreased sense of smell
• Sinus infections (also called sinusitis)
• Ear infections
• Puffiness or dark circles under the eyes
• Fatigue

During an allergic reaction, the body is overreacting to a substance (allergen) and releases chemicals to fight off the suspected invaders. If the allergy causes a severe reaction, known as anaphylactic shock, the body releases a flood of chemicals from the immune system that can cause several changes, such as:

• A drop in blood pressure
• Narrowed airways
• A weak pulse
• Flushed or pale skin
• Hives or a rash
• Nausea
• Vomiting
• A swollen throat or tongue
• Dizziness or fainting

If the person is not treated, anaphylaxis can be fatal. It is imperative to seek immediate medical attention when a person is experiencing a serious allergic reaction.

Common causes of severe reactions include the following:

• Insect stings (wasps, bees, hornets, fire ants)
• Latex
• Food (peanuts, soy, eggs, fish, milk, wheat)
• Medications (penicillin or other antibiotics)

There are several different ways to test for allergies, some of which may be more accurate than others. These include:

• Skin Prick (Scratch) Test — A skin prick test involves making a small mark on the skin with a needle (typically on the back or forearm), then placing 10 to 50 potential allergens. If a person is allergic, a reaction typically occurs within 15 minutes.

• Intradermal Skin Test — This type of allergy test involves injecting a small amount of the suspected allergen into the skin, which can include allergies to airborne irritants, medications, and insect stings.

• Patch Test — Used to determine the cause of contact dermatitis, an allergen is placed onto the skin and is then covered with a bandage. The patches typically remain on the skin for 48 to 96 hours (two to four days), after which time the patient will return to the allergist to have their skin evaluated.

• Blood Test — Blood tests may also be used to diagnose allergies, but these types of tests are generally not as accurate as skin tests, so they are usually only provided if other tests are contraindicated.
