Allergies
An allergy is an immune system response to a foreign substance that’s not typically harmful to your body. These foreign substances are called allergens. They can include certain foods, pollen, or pet dander.The symptoms you experience because of allergies are the result of several factors. These include the type of allergy you have and how severe the allergy is.If you take any medication before an anticipated allergic response, you may still experience some of these symptoms, but they may be reduced.
Causes of allergies
Researchers aren’t exactly sure why the immune system causes an allergic reaction when a normally harmless foreign substance enters the body.Allergies have a genetic component. This means parents can pass them down to their children. However, only a general susceptibility to allergic reaction is genetic. Specific allergies aren’t passed down.Mushroom allergy ,allergy to blueberries , blueberry allergy ,ginger allergy ,potato allergy , cinnamon allergy and lemon allergy are few common food allergies. Animal products , Drugs , Foods,Insect stings , Mold and Plants can be a common cause for allergens.
Allergy Blood Test
When you have an allergy, your immune system treats a harmless substance, like dust or pollen, as a threat. To fight this perceived threat, your immune system makes antibodies called immunoglobulin E (IgE).Allergy blood tests measure the amount of IgE antibodies in the blood. A small amount of IgE antibodies is normal. A larger amount of IgE may mean you have an allergy.Allergy blood tests are used to find out if you have an allergy. One type of test called a total IgE test measures the overall number of IgE antibodies in your blood. Another type of allergy blood test called a specific IgE test measures the level of IgE antibodies in response to individual allergens.A health care professional will take a blood sample from a vein in your arm, using a small needle. After the needle is inserted, a small amount of blood will be collected into a test tube or vial. You may feel a little sting when the needle goes in or out. This usually takes less than five minutes.If your total IgE levels are higher than normal, it likely means you have some kind of allergy. But it does not reveal what you are allergic to. A specific IgE test will help identify your particular allergy. If your results indicate an allergy, your health care provider may refer you to an allergy specialist or recommend a treatment plan.
