Correlation of ImmunoBead (R) and ImmunoSphere (TM) Immunoglobulin G (IGG) tests on detecting antisperm antibody (ASA) on sperm

摘要

Purpose: To determine the correlation with detection of antibody on sperm by a new ImmunoSphere (TM) Immunoglobulin test vs. ImmunoBeads (R). Materials and Methods: A sampling of sperm tested for antisperm antibody (ASA) tested by direct Immunobead (R) 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.
