The patient should be in hospital conditions under the supervision of the attending doctor. Positive reaction – localized or widespread redness (>2 mm), swelling of the point of application of the allergen.
  • Indirect skin test injection. The dose of the stimulus is accompanied by a dose of serum, has high sensitivity to the allergen. The reaction is evaluated through 1 or more days. The result – a hazard assessment of that particular stimulus to the patient.
  • Provocative samples are assigned in case of a mismatch the reactionary characteristics data development of allergies. Distinguish conjunctive, nasal and inhalation tests. The last should be taken in patients with asthma.
  • Decoding results

    After the test, the doctor monitors the body’s reaction to allergens and evaluates the results. If the site of allergen formed the redness, swelling, assumes the existence of allergies. But in some cases, diagnosis requires identification of the degree of sensitivity, that is, the intolerance of the organism to a particular concentration of a substance. In this case it is necessary to take repeat samples, tracking the dosage of the drug.

    All results are measured under bright lighting within 1-3 days after the test. A positive reaction is a papule of more than 2 mm in diameter. A single study may not include more than 15-20 test reactions.
