Interpretation

Alexon Giardia Monoclonal Antigen Capture Enzyme-linked Immunosorbent Assay (ELISA) is a fecal procedure designed to detect a Giardia specific antigen. This procedure is done in parallel with a double centrifugation concentration flotation procedure for Giardia cysts and any other parasites that may be present in the fecal sample.

The results of this test can be interpreted as follows:

Giardia ELISA Positive/Flotation Positive    
The animal is infected with Giardia.

Giardia ELISA Positive/Flotation Negative
The animal may be infected with Giardia but is shedding cysts below the limits of detection by flotation. Alternatively, the ELISA is a false positive that may be seen most frequently when the results are in the low positive range. To resolve the issue, collect a second sample for analysis.

Giardia ELISA Negative/Flotation Positive  
The animal may be infected with Giardia but is producing antigen below the limits of detection by ELISA. Alternatively, the ELISA is a false negative. To resolve the issue, collect a second sample for analysis.

Giardia ELISA Negative/Flotation Negative  
The animal is not infected with Giardia.
