Reference Range:

Comments:

This test has not been evaluated in neonates and reference ranges have not been established for this age group.

Negative results do not exclude the diagnosis of invasive Aspergillosis.

False negative results may be seen in patients receiving concomitant anti-fungals, and patients with chronic granulomatous disease and Jobs syndrome.

A single positive test result (index equal to or greater than 0.5) should be clinically correlated by testing a separate serum because many agents (e.g. food, antibiotics) may cross-react with the assay. False positive results may also be seen in very young children, patients with altered intestinal barrier, and patients infected with other genre of fungi such as Penicillium, Alternaria, Histoplasma, and Geotrichum.

If invasive Aspergillosis is suspected in high-risk patients, serial sampling is recommended.

Aspergillus Galactomannan Antigen
