[Laboratory diagnosis of invasive aspergillosis]

Area of Science:

• Medical Mycology
• Infectious Diseases
• Immunocompromised Host Research

Background:

• Invasive aspergillosis poses significant morbidity and mortality risks in immunosuppressed individuals.
• Delayed diagnosis of invasive aspergillosis contributes to poor patient outcomes.
• Current diagnostic challenges hinder timely intervention.

Purpose of the Study:

• To highlight the importance of early diagnosis in invasive aspergillosis.
• To review current diagnostic strategies for invasive aspergillosis.
• To emphasize the role of laboratory markers in early detection.

Main Methods:

• Review of diagnostic techniques for invasive aspergillosis.
• Integration of imaging (high-resolution computed tomography) findings.
• Utilization of laboratory methods: direct examination, culture, and molecular markers.

Main Results:

• Circulating markers such as galactomannan and Aspergillus DNA are detectable at early infection stages.
• Combination of imaging and laboratory markers improves diagnostic accuracy.
• Early detection facilitates prompt treatment initiation.

Conclusions:

• Early identification of invasive aspergillosis is critical for improving patient survival.
• A multimodal diagnostic approach incorporating imaging and sensitive laboratory markers is essential.
• Advancements in detecting circulating Aspergillus markers offer promising early diagnostic capabilities.
