Methacholine Challenge Test or Bronchoprovocation Test or Bronchial Challenge Test

The Methacholine Challenge Test, also known as the Bronchoprovocation Test or Bronchial Challenge Test, is a specialized diagnostic procedure used to assess airway hyperresponsiveness. During this test, patients inhale increasing concentrations of methacholine, a substance that causes the airways to narrow. By measuring lung function before and after inhalation, the test determines the sensitivity of the airways and helps diagnose conditions such as asthma. The Methacholine Challenge Test is a safe and effective way to evaluate the presence and severity of airway hyperresponsiveness, providing crucial information for accurate diagnosis and guiding appropriate treatment strategies for patients with suspected asthma.
