Aspergillus-Antigen Testing:Introduction, Principle, Clinical Significance, and Keynotes

Aspergillus-Antigen Testing-Introduction, Principle, Clinical Significance, and Keynotes

Introduction Aspergillus species, particularly Aspergillus fumigatus, are major causes of invasive aspergillosis (IA), especially in immunocompromised patients, such as those with hematological malignancies, transplant recipients, or those with prolonged neutropenia. Diagnosis of IA is often challenging because clinical symptoms and radiological findings are nonspecific. Aspergillus …
