Clinical Significance
The Aspergillus EIA is used for the detection of galactomannan antigen in serum. The Aspergillus EIA is an aid in the early diagnosis of invasive aspergillosis. This assay is to be used and test results interpreted in conjunction with other conventional diagnostic procedures such as microbiological culture, histologic examination of biopsy samples and other signs and symptoms for detection of Aspergillus infection.
