The (1,3)-β-D-glucan (BDG) assay, known as the G test, is prone to false-positive results, complicating the diagnosis of invasive fungal diseases.
-
2
A patient with fungal sepsis showed positive G test results for three months despite negative blood cultures, attributed to contamination from sterile gauze.
-
3
The patient's clinical condition improved with antifungal treatment, highlighting the need for careful interpretation of G test results.
-
4
Medical sterile gauze and similar materials contain significant BDG levels, which can lead to misleading G test outcomes.
-
5
Thorough evaluation of G test results is essential when microbiological evidence is lacking, to avoid misdiagnosis and inappropriate treatment.
