• #1 Allergic Rhinitis (Hay Fever): Symptoms & Treatment

  https://my.clevelandclinic.org/health/diseases/8622-allergic-rhinitis-hay-fever

  Allergic rhinitis (hay fever) is an allergic reaction to tiny particles in the air called allergens. […] Your healthcare provider will examine you, ask about your symptoms and evaluate you for other conditions, such as a cold or asthma. They can also perform allergy tests. […] A blood allergy test measures antibodies to an allergen in a sample of your blood. This blood test is called an immunoglobulin E (IgE) test. It can detect most types of allergies, including food allergies. […] Your provider may also recommend a skin prick and/or intradermal test to determine what allergens are causing your symptoms. In a skin prick test, your provider places a small sample of different allergens on your skin (usually on your forearm or back). They scratch or prick your skin with a needle. If you’re allergic to a specific allergen, the area will become red, itchy and irritated in 15 to 30 minutes. Intradermal testing is similar, but your allergist places the allergen underneath your skin. Your skin reacts in the same way it does for a prick test.

  About one quarter (25%) of adults have a seasonal allergy, 7.3% have eczema, and 6.2% have a food allergy. […] Seeking the help of an allergist to test for and diagnose your allergies can help you to feel much better. […] If you have never been diagnosed with allergies but think you might have them, or if you aren’t sure what causes your allergy symptoms, see an allergist. […] Taking a medical history and selecting the right tests are key to getting a good diagnosis. […] Allergy tests should not be ordered randomly, either. […] Blood test and skin test results alone do not diagnose allergies. […] If the results of skin and blood allergy tests are not clear or are inconsistent with the patient’s medical history, allergists rely on their training and experience along with a patient’s medical history and a physical examination—not test results—to make the final diagnosis.

• #1 Allergic rhinitis – Wikipedia

  https://en.wikipedia.org/wiki/Allergic_rhinitis

  Allergic rhinitis is typically triggered by environmental allergens such as pollen, pet hair, dust, or mold. […] Diagnosis is typically based on a combination of symptoms and a skin prick test or blood tests for allergen-specific IgE antibodies. […] Allergy testing may reveal the specific allergens to which an individual is sensitive. Skin testing is the most common method of allergy testing. […] Even if a person has negative skin-prick, intradermal and blood tests for allergies, they may still have allergic rhinitis, from a local allergy in the nose. This is called local allergic rhinitis. […] Local allergic rhinitis is an allergic reaction in the nose to an allergen, without systemic allergies. […] The symptoms of local allergic rhinitis are the same as the symptoms of allergic rhinitis, including symptoms in the eyes.

  Your doctor will make the diagnosis of hay fever based on your allergy history, the timing and appearance of your symptoms and the results of your physical examination. During your physical examination, your doctor will check for signs of inflammation in your eyes, nose and throat. Typically, the lining of the nose is swollen and pale pink or bluish, though it can be red. The doctor often looks for other signs of allergic rhinitis, such as dark circles under the eyes (called allergic shiners), resulting from chronic sinus congestion, wrinkles under the eyes as a result of chronic puffiness around the eyes, and a crease across the nose from frequently wiping it and pushing it upward. […] To identify the specific allergen (allergy-triggering substance) that is triggering your hay fever, your doctor may refer you to an allergist, who can do skin testing. In skin testing, a small amount of a specific allergen is scratched, pricked or injected into the skin. Results are available in 10 to 20 minutes.

  The body produces immunoglobulin E (IgE) antibodies to protect against allergens. […] When the body comes in contact with an allergen, these antibodies signal the immune system to release chemicals such as histamine into the bloodstream. This causes a reaction that leads to the symptoms of hay fever. […] There’s no way to avoid getting hay fever. If you have hay fever, the best thing to do is to lessen your exposure to the allergens that cause your symptoms. Take allergy medicines before you’re exposed to allergens, as directed by your healthcare professional.

  https://www.thermofisher.com/allergy/us/en/living-with-allergies/seasonal-allergies/hay-fever-allergic-rhinitis.html

  Hay fever (allergic rhinitis) is triggered when your immune system has a bit of a freak-out moment over harmless substances such as pollen or animal dander. The body’s defense system sees these allergens and thinks they’re harmful invaders. So, it responds by releasing chemicals like histamines into your bloodstream to combat them. This causes typical allergy symptoms like sneezing, a runny nose, itchy eyes and congestion. […] Together with a healthcare provider, the hay fever diagnosis process starts with a chat about symptoms and family history, followed by a physical examination and, if necessary, performing an allergy test such as a skin prick test or a blood allergy test to identify allergen triggers. […] A blood allergy test, also called a specific IgE test, aids in the diagnosis of hay fever by detecting specific antibodies in your blood that your body produces in response to allergens. After taking a sample of your blood, it’s tested in a lab for these antibodies. If your blood contains IgE antibodies to a specific allergen (like grass or tree pollen in the case of hay fever), it indicates that your body may react allergically to that substance. The results, given as a number, show the sensitization level to the allergen.

  https://gesund.bund.de/en/hay-fever

  Doctors treating people with hay fever will first ask about their symptoms, their everyday life circumstances, and medical history. The doctor can then do a skin prick test to find out whether they are allergic to particular substances. This involves placing potential allergens on the forearm, and then pricking the surface of the skin where the allergens are, so the substances go into the skin. If the skin becomes red and swollen, like a mosquito bite, they have had an allergic reaction to that substance. […] In some cases, doctors prescribe a blood test or what is known as a provocation test. In a provocation test, extracts of the potential allergen are applied to the membranes lining the nose or eyes using a nasal spray or drops. If the lining of the patients nose becomes swollen, they sneeze and their nose starts running, this suggests hay fever.

  An allergist / immunologist has specialized training and experience to diagnose specific allergens that trigger your illness, or to determine if your symptoms are non-allergic. Your allergist will take a thorough health history followed by allergy testing. Skin tests or blood tests are the most common methods for determining your allergic rhinitis triggers. […] Once specific allergens are diagnosed, your allergist / immunologist will work with you to develop a plan to avoid allergens that trigger your symptoms. […] The majority of allergy medications for seasonal allergic rhinitis (hay fever) work best if started before tree pollen is in the air each spring and allergy symptoms develop. If you start taking allergy medications before you first come into contact with spring allergens, the medication can prevent the release of histamine and other chemicals. As a result, allergy symptoms are prevented from developing or are much less severe.
