Consider referring a patient with suspected allergic bronchopulmonary aspergillosis (ABPA) to a respiratory specialist for further evaluation when there is diagnostic uncertainty, when the patient has severe or uncontrolled respiratory symptoms, or when the diagnosis needs confirmation and optimisation of therapy.
Referral is appropriate to confirm the diagnosis, optimise treatment, and exclude other conditions such as bronchiectasis or fungal infections that may mimic or complicate ABPA.
Specialist assessment is also indicated if the patient has frequent respiratory infections, haemoptysis, or symptoms disproportionate to lung function, as these may require further investigation and management.
Early referral can help in managing complications and tailoring corticosteroid or antifungal therapy appropriately.
These principles align with general respiratory referral guidance for complex or severe pulmonary conditions.
