Limitations and Contraindications

Numerous foods (pasta, rice, etc) contain galactomannan.  It is thought that damage to the gut wall by cytotoxic therapy, irradiation, or graft-versus-host disease enables translocation of the galactomannan from the gut lumen into the blood and may be partially responsible for the high false-positive rate of this assay.

Interpretation

A positive result supports a diagnosis of IA. Antigen levels decline in response to antimicrobial therapy.
