Correlation of ImmunoBead® and ImmunoSphere™ Immunoglobulin G (IGG) tests on detecting antisperm antibody (ASA) on
Purpose:
To determine the correlation with detection of antibody on sperm by a new ImmunoSphere™ Immunoglobulin test vs. ImmunoBeads®.
Materials And Methods:
A sampling of sperm tested for antisperm antibody (ASA) tested by direct Immunobead? assay with levels varying from zero to 100% were compared to the percentage of sperm positive for ASA by a new test using immunospheres.
Results:
The correlation was not perfect but, in general, there was good correlation.
Conclusion:
Now that the manufacturer is curtailing the manufacture of immunobeads, it is comforting to see a good correlation with immunospheres.
