4. Methacholine Challenge Test
   • Purpose: Tests airway hyperreactivity.
   • Procedure: Patient inhales increasing doses of methacholine, a substance that can cause airway narrowing.
   • Results: A significant decrease in lung function after methacholine inhalation indicates asthma.
5. Fractional Exhaled Nitric Oxide (FeNO) Test
   • Purpose: Measures the level of nitric oxide in exhaled breath, which can indicate airway inflammation.
   • Procedure: Patient breathes into a device that analyzes exhaled nitric oxide.
   • Results: Elevated FeNO levels suggest eosinophilic airway inflammation, commonly seen in asthma.
6. Allergy Testing
   • Purpose: Identifies specific allergens that may trigger asthma symptoms.
   • Procedure: Skin prick tests or blood tests (e.g., specific IgE tests).
   • Results: Positive reactions to specific allergens can help identify triggers.
7. Chest X-Ray or CT Scan
   • Purpose: Rules out other conditions that may mimic asthma symptoms, such as infections or structural abnormalities.
   • Procedure: Imaging of the chest using X-rays or CT scans.
   • Results: Normal or showing signs consistent with asthma.
8. Blood Tests
   • Purpose: Identifies elevated levels of eosinophils or immunoglobulin E (IgE) that may indicate allergic asthma.
   • Procedure: Blood sample analysis.
   • Results: High levels of eosinophils or IgE can support the diagnosis of allergic asthma.

Diagnosis Confirmation

• Symptom Pattern: Correlation of symptoms with asthma triggers, and improvement with asthma treatment.
• Response to Treatment: Monitoring how symptoms respond to asthma medications, such as inhaled corticosteroids or bronchodilators.

Ongoing Monitoring
