How Does Parallel ENT & Allergy
Allergies are a chronic inflammatory condition that affect the nose, sinuses, ears and throat. They can be triggered by environmental or food allergens. A variety of allergy tests are used to diagnose the source of a patient’s symptoms. They include skin, blood and patch tests.
Patch testing is used to diagnose allergies (contact dermatitis) to substances that you’ve contacted, including cosmetics, fragrances, jewelry, chemicals, soaps and plants. These tests use patches with small discs, chambers or adhesive materials that contain different allergens.
The Parallel ENT & Allergy test is applied to the back of your skin, usually in a specific area. If you develop an allergic reaction, you’ll have red, itchy or scaly skin at the patch site. Allergens that are commonly used for patch testing include nickel (often in jewelry or buckles); latex; fragrances; preservatives; cosmetics; and medications. Some of these substances can cause a delayed allergic reaction, which can take several days to appear on your skin.

The patch test is an effective method to detect allergies. It can help you avoid these allergens in the future and prevent flare-ups of your dermatitis. However, patch testing is not perfect and can lead to false positives and negative results. It may not be conclusive, but it can help your doctor make the right diagnosis and treat your dermatitis.
Allergy skin tests are a simple and inexpensive way to determine what you are allergic to. They can be done in your doctor’s office and are usually painless, though they do sometimes cause mild itching.
During the test, a small amount of allergen solution is placed on your skin and then pricked. Then, your doctor waits about 15 minutes to see if you develop a red, raised bump called a wheal.
The results of this test can show a range of things, including food allergies, environmental allergies, and allergy to certain medicines. Often, your doctor will use these results to suggest changes you can make in your lifestyle to avoid the things that are causing your symptoms.
While skin tests are helpful in confirming clinical diagnoses, they are not 100% accurate. They sometimes indicate an allergy when there isn’t one (false-positive), or they may not trigger a reaction to something you are allergic to when exposed to it in everyday life (false-negative).
Blood tests can give your doctor a lot of information about the different cells, chemicals and proteins in your blood. This can help them diagnose allergies. Your blood will be drawn from a vein in your arm or hand and sent to a laboratory for analysis. This will show the types of cells, chemicals and proteins in your blood and what level they are at.
Most blood tests are safe and don’t require special preparations. They usually don’t take longer than 3 minutes and shouldn’t cause you any discomfort or pain. The test is usually carried out by a nurse or phlebotomist, someone specialised in taking blood. They will clean the area on your arm where they’ll draw the blood and tie a rubber band around it to make it easier for them to see.
Some people may feel faint or dizzy after a blood draw. They should stay seated until the feeling passes. If you feel unwell, tell the person carrying out the test so they can make sure you are more comfortable. When your body is exposed to a foreign substance, such as bacteria, viruses, fungi, harmful toxins or allergens, your immune system is triggered to find and destroy them. This process is known as antigen-specific immune response.
The immune system includes a network of white blood cells and organs that help fight infection. They also produce antibodies that coat antigens, mark them as targets for other white cells and destroy them. If you have allergies, your doctor may use immunotherapy to treat your condition. Immunotherapy can reduce your symptoms and improve your chances of remission.
