PATCH test complex, without PATCH system cost

Allergy is an individual response of the immune system to certain substances. These can be food, plant pollen, book dust, animal hair or chemicals. Allergy can manifest in different ways: from mucosal edema and redness to Quincke's edema and anaphylactic shock.

Allergic contact dermatitis is one of the most difficult allergies to diagnose. Exposure to allergens causes redness and swelling on the skin, spots in the form of eczema, papules. Problem with diagnosis is because of delayed body's reaction to an allergen manifesting itself after a few days, so it can be quite difficult to determine the allergen.

There is no specific treatment for allergic dermatitis and its minor manifestations can be removed by eliminating an irritant causing the body's immune response. In more severe cases, a doctor prescribes antihistamines and corticosteroid ointments.

As it can be quite difficult to identify an allergen, a modern and effective patch testing system is used to identify the substances causing allergic dermatitis. The patch testing is available at the Dobrobut MC network.

The patch testing is the placement of patches on the patient's skin. Due to the high reliability of the obtained results, simplicity and safety of the procedure, the patch testing is the basic examination method and golden standard for diagnosis of allergic contact dermatitis according to the modern European and American clinical guidelines.

Indications

• conditions that may be the result of a delayed type IV contact allergic hypersensitivity reaction, such as contact dermatitis, polymorphic erythema, coin-shaped eczema, lichen planus (Wilson's), psoriasis with localization on the hands, granulomatous or lymphomatoid reactions; 
• deterioration of atopic, seborrheic, hemostatic dermatitis, coin-shaped eczema, suspected concomitant allergic contact dermatitis; 
• drug-induced dermatitis; 
• mucosal reactions: conjunctivitis, stomatitis, vulvitis; 
• before implant placement and prosthetics in dentistry and orthopedics in case of suspected allergic reaction to metals and other materials.

Contraindications

• use of corticosteroids, immunosuppressants or other drugs that affect the state of the immune system. These medications should be discontinued 2 weeks before the PATCH test. In this case, taking antihistamines is a contraindication to testing.
• severe or generalized previous reaction to hapten allergen - is not included in the testing panel (you should inform the doctor at the initial consultation).
• severe or generalized active dermatitis.
• skin damage at the site of application of the PATCH system
• Pregnancy and breastfeeding may be a conditional contraindication, since, despite the extensive experience of PATCH testing, there is still no data on the risk or safety of this diagnostic procedure for mother and child.
