Hundeepithelien Hal Allergy (Dog Epithelia)

Hundeepithelien Hal Allergy is employed in clinical settings to evaluate sensitisation to dog allergens. It is used as part of a standardized skin prick or intradermal test to help clinicians confirm a suspected dog allergy.

• Diagnosis of IgE‑mediated allergy to dog epithelium
• Assessment of occupational exposure to canine allergens
• Support for allergen‑specific immunotherapy planning
• Baseline testing before initiating desensitisation protocols
• Comparative testing when multiple animal allergens are suspected

• The dog epithelium extract in Hundeepithelien Hal Allergy contains protein antigens that bind to specific IgE antibodies on cutaneous mast cells. When introduced into the skin, cross‑linking of IgE triggers mast cell degranulation, releasing histamine and other mediators that produce a localized wheal‑and‑flare reaction, which can be measured to assess sensitisation.

Adverse reactions are generally limited to the test site, but they can vary in frequency and severity.

Common

• Redness (erythema) at the application site
• Small raised bump (wheal) lasting up to 30 minutes
• Mild itching or tingling sensation
• Transient swelling that resolves within an hour

Serious

• Large, prolonged wheal exceeding 15 mm
• Severe itching or urticaria extending beyond the test area
• Systemic allergic reaction (anaphylaxis) requiring emergency care
• Respiratory difficulty or wheezing after testing

Before using Hundeepithelien Hal Allergy, clinicians should consider several safety factors.

• Verify that the patient has not taken antihistamines or other interfering medications within the recommended wash‑out period.
• Confirm no history of severe anaphylaxis to dog allergens.
• Perform a control test with saline to differentiate irritant reactions.
• Use the lowest effective concentration for skin testing.
• Have emergency equipment and trained personnel available during testing.
• Document any prior skin test reactions or dermatologic conditions.

Certain substances can affect the accuracy of skin testing with Hundeepithelien Hal Allergy or increase the risk of adverse events.

Avoid

• Recent use of systemic antihistamines, corticosteroids, or leukotriene antagonists.
• Concurrent administration of other allergen extracts at the same test site.
• Application of topical irritants or anesthetics on the test area.

Use with caution

• Beta‑blockers, which may mask anaphylaxis symptoms.
• ACE inhibitors, which can potentiate angio‑edema.
• Immunosuppressive drugs that may alter IgE responses.
• Pregnancy, where skin testing may be deferred unless essential.
