Mare milk Ab.IgE

This test detects IgE antibodies specific to mare (horse) milk, measuring your immune system's allergic response to this protein. IgE is an antibody your body produces when it identifies a substance as a threat, even if it's harmless. A positive result indicates a mare milk allergy, which can cause symptoms ranging from mild itching and swelling to severe anaphylaxis. This test is useful for diagnosing food allergies in people who consume mare milk products, which are popular in some cultures and alternative medicine practices.

Carya illinoinensis tree Ab.IgG4

This test measures IgG4 antibodies against pecan or hickory tree pollen. IgG4 antibodies develop with prolonged or repeated allergen exposure and may indicate tolerance or desensitization, particularly after allergy immunotherapy. Elevated IgG4 (compared to IgE) can suggest successful allergy treatment. This test is used to assess the effectiveness of allergy immunotherapy and monitor immune tolerance development to tree pollens. It's more specific than IgE for evaluating long-term immune responses.

Wheat dust Ab.IgE

This test measures IgE antibodies against wheat dust, relevant for people with occupational wheat exposure or wheat allergies. Elevated IgE indicates an allergic sensitization to wheat proteins. Wheat allergies differ from celiac disease; allergies cause immediate immune reactions while celiac is an autoimmune condition triggered by gluten. Symptoms can range from itching and swelling to severe anaphylaxis. This test helps identify wheat allergies in symptomatic individuals, particularly important for workers in grain and flour industries, bakers, and others with high wheat exposure.

Sheep milk Ab.IgE

This test detects IgE antibodies against sheep milk proteins, indicating allergic sensitization to sheep dairy products. Unlike cow milk, sheep milk is less common in typical diets but found in specialty cheeses and yogurts. People with cow milk allergies may also react to sheep milk due to protein similarities, though some tolerate it better. Elevated sheep milk-specific IgE suggests risk of allergic reactions with potential symptoms ranging from mild (itching, hives) to severe (anaphylaxis). This test is particularly relevant if you consume specialty dairy products or have unexplained allergic symptoms after eating sheep dairy.

Prunus dulcis tree Ab.IgE

This test detects IgE antibodies to almond tree pollen, indicating a potential environmental or food allergy. Tree nut allergies, including almonds, are among the most common food allergies and can be severe. Some people allergic to almond pollen may also react to almond nuts due to cross-reactivity. Reactions range from oral itching to anaphylaxis. This test helps identify tree nut sensitivity and guide avoidance strategies and treatment options.

(Acer negundo+Betula verrucosa+Quercus alba+Ulmus americana+Juglans californica) Ab.IgE

This test detects IgE antibodies to five common tree pollens that trigger allergic reactions. Tree pollen allergies are a major cause of seasonal rhinitis and asthma, particularly in spring. This panel identifies which tree pollens trigger your immune response, helping explain seasonal symptom patterns. Results guide allergy management timing, allergen avoidance strategies, and treatment decisions including antihistamines, nasal sprays, or immunotherapy.

Bran wheat Ab.IgE

This test detects IgE antibodies to wheat bran, the outer layer of wheat grain, indicating an immediate-type allergic reaction. A positive result suggests that consuming wheat bran products could trigger allergic symptoms ranging from mild itching in the mouth to severe reactions like anaphylaxis. Wheat bran allergy is distinct from celiac disease or gluten sensitivity, representing a true IgE-mediated food allergy. This test helps confirm wheat bran allergy diagnosis in individuals with suspected reactions, guiding dietary avoidance of wheat bran-containing foods and products.

Solanum melongena Ab.IgE

This test detects IgE antibodies against eggplant allergens, indicating a potential food allergy. Eggplant allergies are relatively uncommon but can cause oral itching, swelling, or gastrointestinal symptoms in sensitive individuals. Some people with eggplant sensitivity may also react to related plants in the nightshade family, such as tomatoes or peppers. A positive result helps you identify this vegetable as a trigger and guides dietary planning. It's useful for distinguishing true allergies from other digestive sensitivities.

Bertholletia excelsa recombinant (rBer e) 1 Ab.IgE

This test measures IgE antibodies against a specific protein found in Brazil nuts, helping identify true allergic sensitization to this allergen. Brazil nut allergies can cause reactions ranging from mild itching to severe anaphylaxis. The test uses recombinant protein technology for improved specificity and accuracy. A positive result indicates your immune system has developed an allergic response to Brazil nuts, which may warrant dietary avoidance and consideration of emergency medications.

Corylus avellana Ab.IgE/IgE.total

This test measures hazelnut-specific IgE antibodies as a percentage of total IgE in blood, providing both sensitization detection and relative severity assessment. Hazelnut is a tree nut allergen that can trigger allergic reactions ranging from oral allergy syndrome to anaphylaxis. The percentage indicates what proportion of your immune response is directed at hazelnut allergen. Higher percentages suggest stronger allergic sensitization and greater risk of significant reactions upon exposure.

Cow milk boiled Ab.IgE

This test detects antibodies indicating allergic sensitivity specifically to boiled cow's milk. Boiling milk changes some proteins, so some individuals may react to boiled milk but tolerate raw or pasteurized milk, or vice versa. A positive result suggests potential allergic reactions when consuming boiled milk products. Milk allergies are distinct from lactose intolerance and can trigger immune responses ranging from mild to severe.

Goat milk Ab.IgE

This quantitative test measures the level of IgE antibodies against goat milk proteins. Goat milk allergy is distinct from cow milk allergy, though cross-reactivity can occur. Symptoms may include itching, hives, gastrointestinal upset, or respiratory reactions after goat milk or goat cheese consumption. A positive result indicates IgE-mediated goat milk allergy. This test is useful for individuals exploring alternative milks due to suspected cow milk allergy or those experiencing reactions after goat dairy product consumption.

Triticum aestivum pollen Ab.IgE

This test detects IgE antibodies against cultivated wheat pollen in your blood, indicating allergic sensitivity to wheat pollen exposure. Wheat pollen allergies cause seasonal allergy symptoms like sneezing, nasal congestion, and itchy eyes, typically during wheat-growing and harvesting seasons. This differs from wheat food allergies or celiac disease, which involve different mechanisms. A positive result confirms wheat pollen allergy and helps you anticipate seasonal symptoms and use preventive treatments during high pollen periods.

Fagopyrum esculentum Ab.IgE

This test detects IgE antibodies specific to buckwheat (Fagopyrum esculentum), indicating your immune system's allergic response to this grain. A positive result suggests a potential IgE-mediated buckwheat allergy, which could trigger symptoms from mild oral itching to severe reactions. Buckwheat is used in some flours, noodles, and baked goods. This test helps confirm suspected buckwheat allergies and identifies cross-reactivity risks with related allergens.

Corylus avellana pollen Ab.IgE

This test detects IgE antibodies against hazelnut pollen (Corylus avellana) in your blood. Hazelnut is a tree that releases allergenic pollen in early spring. A positive result suggests your immune system reacts to hazelnut pollen, causing seasonal allergic symptoms like sneezing, nasal congestion, and itchy eyes. Hazelnut pollen allergy often occurs alongside birch pollen allergy due to cross-reactivity. This test helps identify spring pollen allergies and guides allergy management strategies.

Egg yolk Ab.IgE

This test detects IgE antibodies specifically against egg yolk proteins in your blood, indicating a potential allergy to this part of the egg. Egg yolk allergies are distinct from egg white allergies and may occur alone or together. A positive result suggests your immune system reacts to egg yolk, causing allergic symptoms ranging from mild itching to severe reactions. This test helps identify egg yolk sensitivity and guides dietary choices, medication selection, and meal planning.

Pistacia vera Ab.IgE

This test detects IgE antibodies against pistachio proteins, identifying potential allergic sensitivity to pistachios. Pistachio allergy is a tree nut allergy that can cause various symptoms, from mild oral itching to severe reactions including anaphylaxis. A positive result indicates your immune system recognizes pistachio proteins as a threat. Tree nut allergies are typically lifelong and can be serious, making accurate identification essential for safety.

Carya illinoinensis nut Ab.IgE
