An Antibody Was Detected at Immediate-Spin and 37° C That

An antibody was detected at immediate-spin and 37° C that appeared to have anti-Le? specificity.To confirm the antibody identity and determine if there were other antibodies in the serum,a Lewis neutralization technique was performed.
Patient serum + Lewis substance = 0
Patient serum + saline control = 1+
Neutralized serum + Fy(a+b+) red cell = 0
What conclusion can be made from these results?

A) Anti-Le^b is confirmed.
B) Antibody was diluted, therefore no conclusion can be made.
C) Antibody was not neutralized, therefore anti-Le^b has not been identified.
D) Antibody other than anti-Le^b is most likely in the serum.
