The consultation will be most productive if the patient provides medical documentation of the results of previous examinations and previous expert opinions.

It is welcome to have photo and video materials of skin manifestations of allergies, breathing disorders (shortness of breath, whistling, wheezing), etc. in the absence of complaints at the time of consultation.

If you have bronchial asthma, bring your own “pocket” medication delivery devices (metered-dose aerosol inhalers, powder inhalers, etc.) to your appointment.

avoid physical activity 1 hour before the test;

• avoid large meals for 2 hours before the test;

• do not smoke for 1 hour before the test;

• do not drink alcohol for 8 hours before the test;

• stop bronchodilators:

• short-acting beta-agonists (salbutamol, fenoterol) 4-6 hours before the test;

• short-acting muscarinic (cholinergic) receptor antagonists (ipratropium bromide) 12 hours before;

• long-acting beta-agonists (formoterol, salmeterol) 24 hours before;

• prolonged theophyllines (theophylline, theotec, theotard) 24 hours before;

• “ultra-long-term” beta-agonists (indacaterol, vilanterol, olodaterol) for 36 hours;

• long-acting muscarinic (cholinergic) receptor antagonists (tiotropium bromide) within 36 hours

• stop decongestants (nasal vasoconstrictors) 4 hours before the test

Spirometry is performed:

1. Patients who are able to perform the necessary breathing maneuvers due to age and/or mental status (children over 5 years old, in the absence of cognitive impairment, etc.).

2. In the absence of the following conditions:

• the first week after myocardial infarction;

• decrease or significant increase in systemic blood pressure;

• severe heart rhythm disturbances;

• decompensated heart failure;

• uncontrolled pulmonary hypertension;

• acute right ventricular failure;

• clinically unstable forms of pulmonary thromboembolism;

• a history of syncope, sudden convulsive attacks associated with coughing or forced breathing;

• aneurysms of cerebral vessels;

• recent concussion with persistent symptoms;

• in the first 4 weeks after operations on the brain, chest and abdominal cavities;

• in the first week after ophthalmological operations and operations on the paranasal sinuses and middle ear;

• pneumothorax;

• complicated pregnancy;

• late pregnancy;

• pain syndrome that prevents the correct performance of spirometry;

• acute otitis media, sinusitis.

Skin tests are carried out:

• outside of exacerbation of an allergic chronic disease;

• outside of exacerbation of somatic chronic disease;

• outside of an acute infectious disease;

• no earlier than 1 month after suffering an acute allergic reaction.

Medications that should be discontinued before skin testing:

• 1st generation H1-histamine blockers (chloropyramine, diphenhydramine, clemastine, dimethindene, mebhydrolin) – 3 days before;

• 2nd generation H1 histamine blockers (cetirizine, levocetirizine, loratadine, desloratadine, fexofenadine, rupatadine, etc.) – 1 week;

• Antihistamine nasal sprays and eye drops – 3 days in advance;

• Antihistamines used for non-allergic diseases – phenothiazines

antiemetics (promethazine, prochlorperazine) or drugs for dizziness/motion sickness or insomnia (meclizine, doxylamine) – 2 weeks before;

• H2 histamine blockers (famotidine, cimetidine) – 48 hours before the test;

• Topical glucocorticosteroids (cutaneous hormonal agents) – 1 week;

• Calcineurin inhibitors (Tacrolimus) – 1 week before

• Tricyclic antidepressants (amitriptyline, doxepin, nortriptyline, protriptyline, imipramine,

trimipramine) – 2 weeks

• Biological agents (Omalizumab) – within 6 months

To conduct a prick-prick test, you need to bring products to which you need to determine sensitivity.
