Hi there, I was hoping that someone could help me out with the following grouping anomalies and what their interpretation is.

 

1)what group would this be - reaction with anti-A -4+, Anti-B - neg, PVP-neg, A1 cells - 2+, B cells 4+ and O cells - 2+

 

2)what causes this?  reaction with anti-A - 4+, Anti-B -1+, PVP-neg, A cells- neg, B cells-4+ and O cells-neg.

 

thanks

Sorry to be a pain, but what does PVP mean?  Is it the auto (patient versus patient)?

hi yes it is sorry

1.  You've probably got a group A patient with a cold (non-ABO) antibody.  Try putting up a room temperature identification panel.  It'll probably come up as a P1 or an M or a Lewis or something like that.  Or might be an I

2.  Depends on your reagents but if you are using a reagent that picks up aquired B, that would be my first reaction

Sorry NAN47, I meant to answer earlier, but my answer would have been identical to Anna's.
