On asthma suspicion, the doctor will examine and check your lung function. While the interception of the lung is a whistling or hissing sound on the exhale (wheeze and hum). The dynamics of respiration is measured by spirometry or Bodyplethysmografie and determine the gas content of the blood.

During bronchial asthma diagnosis investigation, the physician doctor examined using a small device (peak-flow meters) the highest flow velocity of the air during a forced exhalation. This device is also important for the self-measurement at home. An X-ray examination of the lungs is carried out in asthma diagnosis to rule out other diseases that also cause shortness of breath and coughing.

Allergic Asthma

In addition to the above studies of allergic asthma is trying to identify the triggering substances (allergens) to. To the doctor, blood samples (immunoglobulins investigation) takes and carries skin tests (prick test) to verify a possible hypersensitivity through to specific allergens.

In unclear cases, may in the investigation of an inhaled asthma – bronchial, nasal or conjunctival – provocation test should be conducted. During this investigation, the suspect standing irritant (allergen inhalation). The asthma doctor measures the lung, the patient inhales the pure carrier solution, followed by a low-dose allergen solution. At intervals of five to ten minutes, asthma physician examined whether lung function deteriorates or if patient develops symptoms of asthma (e.g. difficulty in breathing). After an hour, no reaction has occurred, the patient inhales a slightly higher concentration of the allergen. The asthma doctor uses the test continued until a reaction occurs or until the patient has inhaled a quantity of the undiluted allergen solution. Even if the dose increased gradually, it can lead to cardiovascular problems or asthma attack.
