There are certain tests for diagnosing asthma. You need to pass a biochemical analysis of blood to the level of total protein and conduct a sputum analysis (for asthma, it contains Kurshman spirals and Charcot-Leiden crystals, as well as a large number of eosinophils and neutrophils). Also, in the diagnosis can help chest radiography.
There are also special diagnostic methods: allergy tests - intradermal injections of various allergens, this helps to identify the allergen provoking asthma attacks, and peak flowmetry, which helps to estimate the amount of inhaled and exhaled air. In asthma, these figures are reduced.
