sona Aspergillus Galactomannan Lateral Flow Assay for serum and BAL samples IMMY 50 tests

The sōna Aspergillus Galactomannan Lateral Flow Assay (Asp GM LFA) is an immunochromatographic test system for the qualitative detection of Aspergillus Galactomannan in serum and BAL samples.
The Asp GM LFA is a test which, when used in conjunction with other diagnostic procedures such as microbiological culture, histological examination of biopsy samples and radiographic evidence, can be used as an aid in the diagnosis of aspergillosis.
The LFA is constructed by having Aspergillus Galactomannan specific antibodies conjugated to colloidal gold that binds to any Galactomannan that may be present in the specimen sample as it wicks up the test strip. If any binding occurs, the antibody-antigen complex will migrate up the strip by capillary flow until it is captured by the Aspergillus Galactomannan specific antibodies in the test line, resulting in the formation of a visible test line. Additionally, control antibodies conjugated to gold wick along with the specimen and are captured by the control antibodies present on the control line, regardless of positive or negative test results. Positive test results create two lines (test and control lines) and negative results form only one line (control line). If a control line fails to develop, the test is not valid.
The sōna LFA Cube Reader (LFARDR) supplied separately is intended to be used as an aid in the interpretation of results of the sōna Aspergillus Galactomannan Lateral Flow Assay and removes objectivity when reporting results. Using an LED light source at 525 nm to read the test strip the Cube Reader displays test results in two ways: 1) an index value displayed numerically and 2) as “POS” or “NEG”.
