Hi,

I cannot find Aspergillus fumigatus Ag on Serum. The only one I find is on Tissue. Thank you!

Hello Maria,

Does your assay happen to test for the galactomannan antigen, that is common across several fungi genus. Here’s the RELMA definition : Galactomannan is a polysaccharide cell wall component in certain species of fungi. The assay is used for the early diagnosis of invasive aspergillosis in immunocompromised patients undergoing hematopoietic stem cell transplantation and in patients with hematological malignancy. Other fungal sources galactomannan include Alternaria, Penicillium and Paecilomyces species, but these fungi are rarely seen in invasive disease.

This is the analyte I use in client mappings; there are several serum specimens available.

Best regards,

Pam
