Is there such a thing as a red meat allergy?

Ticks and Red Meat Allergy



In recent years it has been discovered that a tick bite can lead to a delayed food allergy to mammalian meat products (meat from any kind of mammal). Red meat typically includes beef, pork, goat, and lamb, but patients can still tolerate chicken, turkey, and fish. In contrast to other food allergies, which are typically immediate (5-30 minutes), red meat allergy usually occurs 3 to 6 hours after ingestion. Another common name for this is Alpha-gal allergy. The Lone Star tick, Amblyomma americanum, is thought to be the sensitizing tick in the United States. Typical symptoms include hives, angioedema (swelling of the soft tissues), upset stomach, or anaphylaxis. Several patients report waking in the middle of the night with symptoms. This often makes diagnosis very difficult. History, along with blood work and/or a skin test, is key for making a diagnosis. Treatment consists of ALL red meat avoidance and carrying an epinephrine auto injector. If you think you might be allergic to red meat, contact us. We can help!

Gel Nails and Allergic Contact Dermatitis

By Dr. Nicholas Cline • July 10, 2026
Allergic Contact Dermatitis from Gel Nail Polish (HEMA / Methacrylates) What is happening? The itching, swelling around the cuticles, small blisters, and peeling skin are signs of allergic contact dermatitis — an allergic reaction caused by chemicals in gel nail polish called (meth)acrylates. The most common culprit is a chemical called HEMA (2-hydroxyethyl methacrylate). Why did this happen after months of use? This type of allergy is a delayed immune reaction. The body needs repeated exposures — often over many months — before the immune system becomes sensitized. This is why the product may have seemed perfectly fine at first. Why are home kits riskier? Gel nail polish must be fully "cured" (hardened) under a UV or LED lamp. When the polish is fully cured, the chemicals become locked into a solid polymer and are no longer irritating. The problem occurs when the polish is not fully cured — leftover uncured chemical monomers sit on the skin and trigger the allergic reaction. Home kits are riskier because: The lamp may be underpowered or mismatched to the polish formula Layers may be applied too thickly for the lamp to cure completely Curing times may be too short Technique without professional training increases skin contact If you're having an allergic reaction to at-home gel nail kits, discontinue use and review your products and technique to ensure quality ingredients, sufficient curing times, and properly powered lamps.

Mail-in Allergy Testing

By Dr. Nicholas Cline • May 27, 2026
If you spend any time browsing the internet or social media, you’ve likely seen advertisements for mail-in allergy kits. They promise to test for hundreds of food intolerances and environmental sensitivities using just a few strands of your hair or a quick saliva swab. It sounds incredibly convenient, painless, and comprehensive. But if it sounds like a gimmick, it probably is. While these mail-in tests are heavily marketed, they often lack scientific backing and can leave patients feeling more confused than comforted. The Science of Allergy Testing. What Are We Looking For? To understand why hair and saliva tests don't work, we have to look at how the immune system reacts to allergens. When you have a true allergy, your body produces a very specific type of antibody called IgE (Immunoglobulin E) . These antibodies bind to mast cells (allergy cells), which are on high alert to protect you from perceived invaders like pollen, dust mites, or specific food proteins. The fundamental flaw with mail-in hair and saliva kits comes down to basic biology: Wrong Locations: Mast cells and IgE antibodies are not traditionally found in your hair follicles or saliva. Unreliable Results: Because these testing methods are looking in the wrong place, they are highly unstandardized and unvalidated. You are highly likely to get a flood of false positives or false negatives that are impossible to interpret accurately. What the Experts Say: Major medical organizations strongly advise against these methods. The National Institute of Allergy and Infectious Diseases (NIAID) explicitly recommends against using hair analysis for food allergy evaluations due to a lack of diagnostic value. Furthermore, the American Academy of Allergy, Asthma & Immunology (AAAAI) and the American College of Allergy, Asthma & Immunology (ACAAI) have issued strong practice guidelines stating that hair analysis should not be used to evaluate food allergies. The Big Misconception: IgE vs. IgG Many mail-in companies charge anywhere from $150 to upwards of $600 for "sensitivity" panels. When patients produce these multi-page reports, the testing is almost always checking for IgG (Immunoglobulin G) antibodies, not IgE. There is a massive difference between the two:
