What is an allergist?
An allergist, also called an immunologist, is a specialized medical practitioner who focuses on conditions that affect the immune system. The immune system is a detailed network of cells, organs, and tissues that protects the body from diseases and foreign substances. Allergists diagnose and treat various immune system disorders, which can include:
- Allergies and allergic disorders: Allergies occur when the immune system overreacts to substances you ingest, inhale, or touch, leading to various symptoms.
- Asthma: This is characterized by inflammation of the airways in the lungs, often triggered by environmental factors.
- Primary immunodeficiency disorders: These genetic conditions disrupt the normal functioning of the immune system, and there are over 200 different types.
Allergies are widespread worldwide and have steadily increased in prevalence over the last 50 years. Today, almost 50% of children are affected by at least one allergy. Allergies can result from various triggers, including pollen, pet dander, medications, and different foods. They represent an exaggerated immune system response, and allergists use their expertise to diagnose and manage these conditions effectively.
Education and training
Allergists are physicians who undergo specialized training in immunology, with a particular emphasis on allergies. Like many other medical professionals, they usually follow a structured path that begins with medical school, where they earn their certifications in either internal medicine or pediatrics.
This educational journey typically comprises the following components:
- Four years of a science-rich undergraduate degree.
- Approximately four years of medical school are required to acquire a fundamental medical education.
- A three-year residency program dedicated to honing their skills and expertise within their chosen specialty.
- Completing an examination to earn certification from either the American Board of Pediatrics or the American Board of Internal Medicine.
- A subsequent two-to-three-year allergy and immunology fellowship, followed by an examination to achieve certification from the American Board of Allergy and Immunology.
This rigorous educational and training process equips allergists with the knowledge and abilities to provide specialized care in immunology and allergy-related fields.
What does an allergist do?
When you visit an allergist near you, depending on the type of allergy, the specialist can perform various responsibilities, such as:

- Assessing lung function and providing asthma diagnoses.
- Prescribing medications or devices to prevent, treat, or mitigate the severity of allergic reactions and asthma attacks.
- Offering guidance on lifestyle adjustments to minimize exposure to asthma and allergy triggers.
- Administering allergy shots and other forms of immunotherapy to reduce allergic reactions.
- Diagnosing immunodeficiency disorders.
- Suggesting strategies to prevent infections for individuals with immune disorders.
- Providing intravenous immunoglobulin (IVIG) treatment for specific immune disorders.
- Conducting drug desensitization to enable the safe use of crucial medications.

How does an allergist diagnose an allergy?
If you develop watery eyes or a stuffy, runny nose, you might have a cold. However, if these symptoms appear only outside, near pets, or when eating certain foods, you might have an allergy.
Some people with allergies sneeze frequently or develop rashes or hives, which can spread to other areas of their body. Others can experience severe reactions, such as difficulty breathing, and need medical assistance immediately.
Here are a few tests an allergist may perform to confirm if you are having an allergic reaction.
A skin test is the most common method to check for allergies. It gives the fastest and most accurate results.
The test doctors use most often is called a scratch test. In this test, the doctor or nurse places a small drop of an allergen on your skin, typically on the inside of your arm or on your back. Some common allergens include mold, pet skin and fur, foods, pollen, and certain medicines.
Next, they will prick your skin or make a small scratch on the surface to allow the allergen to enter underneath. The skin prick does not make you bleed. You will feel it, but it should not hurt. Some doctors use a small needle to insert the allergen beneath the skin layers.
The doctor will likely test several allergens at the same time. If one of the areas swells and turns red like a mosquito bite, it means you are allergic to that allergen. It usually takes around 15 minutes to see the results.
When the test ends, the doctor or nurse will clean your skin and apply some cream to relieve itching. Any swelling from a reaction usually fades within 30 minutes to a few hours.
Some medicines can interfere with the tests. If you must discontinue taking any medicines before the test, check with your provider.
If you take medicine that can affect skin test results, have sensitive skin, or have experienced a severe reaction to a skin test, your doctor might recommend a blood test instead.
The allergist sends your blood sample to a lab, and they receive the results within a few days.
If your doctor suspects you might be allergic to a specific food, they may ask you not to consume it to see if that helps. This is called an elimination diet.
You will cut out that food for nearly two to four weeks and see if you experience any allergy symptoms during that time. If you do not, your doctor will ask you to start eating that food again to determine if your symptoms return. If they do, there is a good chance you are allergic to those foods.
Your doctor might also recommend an oral food challenge. However, you should only do this in a medical office with an allergist present.
Your doctor will give you tiny amounts of the food you might be allergic to and watch for symptoms. They will slowly give you larger doses if you do not have any. If symptoms start, they will stop the test.
The most common symptoms are hives or a flushed feeling. If that happens, they will give you medicine to help you feel better. You can safely rule out that food allergy if you do not react.
What can you expect for your first visit with an allergist? How do you prepare for it?
When allergy symptoms become unmanageable with over-the-counter antihistamines and decongestants, it is advisable to see an allergy specialist. The next step is to book an appointment once you find the best allergist near you. However, before scheduling one, you should prepare a list of things to discuss with your specialist. Here are some tips to get started.
When to see a doctor: Many people experience allergy symptoms for years and go without seeking medical assistance. However, it is important to seek medical attention if symptoms become severe or disruptive to daily life. If over-the-counter medicines do not offer relief or you must take them for longer than a few weeks, it is time to see a doctor.
If you or your child experiences asthma symptoms, seek medical attention immediately. Asthma symptoms may include excessive coughing, wheezing, difficulty breathing, and tightness in the chest. Allergies can make asthma symptoms worse and can be life-threatening if not treated.
Maintain a symptom diary: Diagnosing allergies involves identifying the time of year, allergy triggers, and circumstances in which you experience symptoms. Recording your symptoms in a journal or calendar can be helpful. If you have food allergies, keeping a food diary and recording any symptoms related to your diet would be beneficial.
Making an appointment: If your case is moderate to severe or your provider does not feel they can treat it, they may refer you to an allergy specialist. When scheduling your appointment, ask your doctor about any special instructions for preparing for your appointment, such as paperwork requests or fasting requirements before testing.
During the visit, your doctor will likely compile a complete family medical history and ask a series of questions about your medical history. Bring any medical records you have or ask for them to be transferred before your visit.
The doctor may ask what medications you have tried and if any have successfully managed your symptoms. During your visit, bring any creams, sprays, ointments, or medications you have used for the doctor to review.
Preparing a list of questions for your physician before your appointment is helpful. Some sample questions include:
- Can I change my environment or lifestyle to control these symptoms?
- What should I expect from the treatment you are prescribing?
- Are there any side effects I should be aware of regarding the medication you have prescribed?
- Could you please explain the available tests to determine the cause of my allergic reaction?
After the visit: Testing may be needed if you are diagnosed with food or airborne allergies. Allergists may test your skin to determine how it reacts to different substances. Based on those results, your allergist will recommend a treatment plan, including allergy shots, avoiding certain allergy triggers, prescription medications, or lifestyle changes to alleviate your symptoms. If you have any questions after your appointment, contact your doctor. If medication is prescribed, they suggest scheduling a follow-up appointment.

Allergy statistics in Pennsylvania and the United States
A 2021 study by the Asthma and Allergy Foundation of America revealed the state of allergies in Pennsylvania, specifically in its metropolitan areas. The study indicates that several urban areas, primarily in the northeast region of the United States, are expected to experience a "worse than average" year for seasonal allergies. This includes five metropolitan areas within Pennsylvania.
Overall findings:
Among these findings, Scranton, Pennsylvania, emerged as the most challenging place to live with allergies, placing it within the "worse than average" category. Pittsburgh, another city in Pennsylvania, also shared this distinction by securing the fifth position on the list. Allentown, Pennsylvania, ranked 25th in the "worse than average" category. Philadelphia, the state's largest city, was placed at the 28th position, categorizing it as "average." Notably, Harrisburg, Pennsylvania, achieved a "better than average" rating, ranking 78th, with a score below the national average.
Spring allergies:
Several Pennsylvania cities appeared in the top ten metropolitan areas for spring allergies. Scranton and Pittsburgh were among the most challenging places to live with spring allergies, and additional Pennsylvania cities like Allentown, Philadelphia, and Harrisburg were in the top 100.
Fall allergies:
The study also identified the top ten metropolitan areas for fall allergies, with Scranton, Pennsylvania, leading the list. Pittsburgh, Pennsylvania, was again among the top ten regions for fall allergies. Buffalo, New York, also made an appearance on this list.
Allergies across the U.S.:
Data from the CDC's National Center for Health Statistics highlighted the prevalence of allergic conditions across the United States in 2021. Almost one in three U.S. adults and more than one in four U.S. children reported having seasonal allergies, eczema, or food allergies. The data revealed disparities among demographic groups, emphasizing the importance of allergy awareness and care in the United States. These findings underscore the significance of proactive allergy management and the need for accessible healthcare resources.
