Types Of Allergy Blood Tests
Allergy blood tests detect and measure the amount of allergen-specific antibodies in your blood. When you come into contact with an allergy trigger, known as an allergen, your body makes antibodies against it.
The antibodies tell cells in your body to release certain chemicals. These chemicals are what cause allergy symptoms. Immunoglobulin E is an antibody that’s strongly linked to the body’s allergy response.
Allergy blood tests usually screen for at least 10 of the most common allergy triggers, including dust, pet dander, trees, grasses, weeds, and molds related to where you live. They are also particularly helpful in diagnosing food allergies.
Allergy blood tests may be referred to as immunoassay tests and include:
- Enzyme-linked immunosorbent assay
- Radioallergosorbent test
The ELISA test measures the amount of allergen-specific antibodies in your blood.
The RAST test also looks for specific allergen-related antibodies in order to identify your allergy triggers. Since the introduction of the ELISA test, RAST testing has not typically been used.
Allergies can cause an increase in certain types of white blood cells. Blood tests to check your white blood cell counts, including a count of a type of white cell called an eosinophil, may also be done if your doctor thinks you have allergies. However, it is important to keep in mind that many other health conditions can cause an increase in white blood cells.
Talk With Your Doctor About Allergy Testing Or Allergy Shots
Allergy testing can help your care provider diagnose your exact allergies and come up with a treatment plan to help relieve your symptoms.
Allergy tests are pretty simple. The tests are performed on your skin at your clinic, to determine what allergens are causing your symptoms.
Depending on how severe your allergies appear to be, your doctor may recommend immunotherapy with allergy shots to help reduce and maybe even eliminate your bodys reaction to environmental allergens.
These shots help teach your body to not be allergic and are given over the course of a couple of years until a target dose is reached. Once the right dosage has been reached, your doctor will work with you on a maintenance schedule.
Allergy shots are the most effective way of treating allergies and work better than most prescription medications. A course of allergy shots can give you long-term symptom relief for three to five years. Many people have symptom relief the rest of their life. You can discuss the cost of allergy shots with your insurance provider.

What Allergy Treatments Are Available
Treatments can help a great deal, says Dr. Hsu. Allergy treatment has changed over the past 10 years, with a number of first-line medications now available over the counter, she says. So, while we have lots of consultations with patients, we dont necessarily send a prescription to the pharmacy. We often advise people on what to buybut we want to be very specific, because there are certainly a lot of over-the-counter medications that we would not recommend as first-line treatments.
For instance, she might start with antihistamines for itching and runny nose, steroid nasal sprays for nasal passage congestion, and antihistamine eye drops for ocular symptoms. If a patient is still uncomfortable, she might recommend a decongestant, but not for daily use, since its a medication patients can become overly reliant on. Likewise, some patients should avoid antihistamines that are excessively sedating, she says.
The problem is that some people think theyll just grin and bear it. But… you can take steps to minimize those weeks of misery.Yale Medicine pediatric allergist Stephanie Leeds, MD
Its helpful when patients have a skin or blood test to find out exactly what they are allergic to. If you are really symptomatic, its helpful to get tested at least once. I dont think you need to be re-tested year after year, but at some point, establishing the specific triggers can be helpful, because then you can take steps to avoid exposure, Dr. Leeds says.
Handling An Allergic Reaction In The Wild
So many different variables can create an allergic reaction. Whether its an anaphylactic reaction to a food like peanuts or tree nuts, a skin reaction to poison oak or poison sumac, or a dangerous reaction to a bee sting or a specific medication, they can sneak up on us and they can be really scary. Food, plant, insect, and medication allergies can all quickly become a serious issue.
You should be worried about the same allergies in the backcountry as we worry about in the front country. These include food, medications, and bee stings. Tod Schimelpfenig, curriculum director of National Outdoor Leadership School Wilderness Medicine, told The Dyrt. Hes been with NOLS for the last 45 years and also serves as an EMT, so its safe to say hes a good guy to have around when things dont go as planned.

Reducing Redness On The Face
To get remove redness on the face, its helpful to have a daily skin care routine. Every day, wash your face with a gentle cleanser or water, pat the skin dry on the areas that are inflamed to soothe them, and then use a water-based moisturizer such as a cream or lotion to lock in moisture and reduce redness. This can really help to reduce inflammation fast!
Looking into your facial soaps, cleansers, and make-up products can help to see if there are harsh ingredients such as sulfates, exfoliants, or fragrance that might be causing your skin to break out.
Eczema on the face is typically patches of red and inflamed skin. This makes facial dermatitis especially difficult for children and adults to deal with, as it can be quite obvious and apparent!
Inflammation can also worsen due to outdoor triggers such as poor air quality such as pollution, dust, and dry weather. Because the skin has very little protection, its important to remove potential irritants and triggers.

Allergies That Last A Lifetime
Some childhood allergies can grow less severe over time. This is particularly true for egg allergy. However, most allergies last throughout life.
You can also develop allergies as a result of repeated exposure to a toxin, such as bee stings or poison oak. With enough cumulative exposures over a lifetime, your immune system can become hypersensitive to the toxin, giving you a severe allergy.
Treating Allergies On The Skin
For allergic reactions that cause skin symptoms, including those associated with allergens found in animal saliva, poisonous plants, drugs, chemicals and metals, additional treatment options include:
- Topical corticosteroid creams or tablets. Corticosteroids contain steroids that reduce inflammation and itching. Mild forms of these creams can be found online, and a doctor can prescribe stronger versions.
- Moisturizing creams. Emollient creams with soothing ingredients, such as calamine can treat skin reactions.
- Bite or sting medication. Medication targeted to reduce allergic reactions to insect bites or stings have a similar effect to other allergy medications.
- Ice pack. Applying an ice pack wrapped in cloth to the area for 10- to 15-minute intervals can reduce inflammation.

What To Do When You Have An Allergic Reaction In The Woods
This post is brought to you by our friends at Wild Zora, who produce delicious backpacking food that are gluten-free, grain-free, nut/peanut/tree nut-free, and soy-free.
Allergy season: that time when were torn between our excitement to get outside, and the misery of runny noses and itchy throats, often due to pollen. Lets be honest, allergies can really get you down when youre camping or hiking, but theres a big difference between sniffling and being unable to breathe.
While seasonal allergies are annoying on a hike, they pale in comparison to more serious reactions such as anaphylaxis. A severe allergic reaction can be downright scary and life-threatening, so its important to know how to deal with the situation if it arises, especially in the wilderness.
Even if you dont suffer from any serious allergies yourself, understanding allergies can help save a life when someone around you does.
Allergy Blood Test Results
A positive result means allergy-specific antibodies were detected in your blood. This is usually a sign of an allergy.
The blood test will reveal what exactly you are allergic to. However, you can test positive for something but never have had an allergic reaction to it.
A negative result means you probably do not have a true allergy. That means your immune system probably does not respond to the allergen tested. However, it is possible to have a normal allergy blood test result and still have an allergy.
Allergy blood test results should be interpreted with caution by an allergy specialist. Your doctor will also consider your symptoms and medical history when diagnosing a specific allergy.

Common Flu Shot Side Effects
Repeat: The flu vaccine won’t give you the flu, but you can experience mild symptoms because of how the vaccine works.
“The flu vaccine is designed to stimulate your immune system to build antibodies to the virus. That stimulation can cause a low-grade fever, a decrease in appetite, loose stool, mild fatigue or myalgia and even a scant cough,” Teague says.
According to Teague, these symptoms usually resolve after a few days and are no cause for alarm. You may also experience some redness, swelling or soreness where the shot was injected, which is also normal.
The CDC says you can experience “flulike” symptoms after getting the vaccine, such as:
- Soreness, redness, and/or swelling at the injection site
- Headache
- Nausea
- Muscle aches
The symptoms listed above should resolve in a few days. Also, keep in mind not everyone has symptoms, but those are the most common. When it comes to other symptoms, or symptoms that last longer, it’s important to keep in mind that you can still catch a cold, or other virus, right after you get the flu shot.
So if you experience other symptoms that seem like the flu, it could be another illness and it doesn’t mean the shot made you sick. The flu shot also takes about two weeks to become effective at protecting you from the flu, so you could technically catch the flu within that two-week window.
British Columbia Specific Information
