title: Correlation of ImmunoBead® and ImmunoSphere™ Immunoglobulin G (IGG) tests on detecting antisperm antibody (ASA) on sperm.
abstract: OBJECTIVE
  To determine the correlation with detection of antibody on sperm by a new ImmunoSphere™ Immunoglobulin test vs. ImmunoBeads®.
  
  
  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.
  
  
  CONCLUSIONS
  Now that the manufacturer is curtailing the manufacture of immunobeads, it is comforting to see a good correlation with immunospheres.
