Leszczyna Pospolita Prick Test Hal Allergy (Corylus Avellana L.)

The product contains a homeopathic extract of Corylus avellana. When the solution is introduced into the skin, it binds to mast‑cell bound IgE that is specific for hazel allergens. Cross‑linking of IgE triggers mast‑cell degranulation, producing a localized wheal‑and‑flare response that indicates sensitization.

The amount of solution applied is determined by the prescribing clinician or allergist. Typically a single drop is placed on the skin and a lancet is used to create a superficial puncture. Exact dosing and administration protocol should follow the practitioner’s standard testing guidelines.

Safety data are limited. The product should only be used in pregnancy or lactation if the expected diagnostic benefit outweighs any potential risk. Clinicians are advised to discuss the decision with the patient and consider alternative testing methods when appropriate.

Leszczyna Pospolita Prick Test is a homeopathic preparation, whereas many alternative reagents are standardized extracts. Both aim to elicit a skin reaction, but the homeopathic form may have different potency levels. Choice depends on clinician preference, regulatory requirements and the specific diagnostic protocol used.

Store the prick test solution at ambient temperature, preferably below 25 °C. Keep it in the original sealed container, protect it from direct light and moisture, and avoid freezing. Ensure the vial is labeled with the expiry date and batch number before use.

The solution is applied topically to the forearm or back. A sterile lancet creates a shallow puncture through the drop, allowing the extract to contact the dermal immune cells. After a standard observation period (usually 15–20 minutes), the size of the wheal and flare is measured to interpret the result.

The most serious risks are systemic allergic reactions, including anaphylaxis, generalized urticaria, bronchospasm, hypotension, and angioedema. Immediate medical supervision and emergency equipment should be available during testing to manage any severe reaction promptly.

Patients with a known severe reaction to hazel pollen, those on beta‑blockers or ACE inhibitors who cannot be monitored closely, and individuals with uncontrolled asthma or cardiovascular instability should avoid this test. Children under two years of age are also not recommended for this specific preparation.
