lab217 Posted June 7, 2015 Share Posted June 7, 2015 When testing for A subgroups, do hospitals routinely test the patient's plasma with A2 cells along with A1 lectin testing on the red cells even when the A1 lectin is positive? Link to comment Share on other sites More sharing options...
Malcolm Needs ☆ Posted June 7, 2015 Share Posted June 7, 2015 Certainly, in the UK, this is not, to say the least, a routine procedure. lab217 and Ensis01 2 Link to comment Share on other sites More sharing options...
David Saikin Posted June 8, 2015 Share Posted June 8, 2015 I only use the A1 lectin if I am dealing with a reverse grouping discrepany (grA backtypes as an O). Ensis01 and lab217 2 Link to comment Share on other sites More sharing options...

L106 Posted June 8, 2015 Share Posted June 8, 2015 No. If the patient's red cells demonstrate a positive reaction when tested with Anti-A1 Lectin it indicates that the patient is an A1 individual (and there is no reason to test the patient's plasma against A2 cells.) lab217 1 Link to comment Share on other sites More sharing options...
Malcolm Needs ☆ Posted June 8, 2015 Share Posted June 8, 2015 Actually, I have to disagree L106, as, if the anti-A1 being used is Dolichos biflorus, this lectin will also detect Tn activation and Cad polyagglutinability - both highly unlikely, but both possible.

L106 Posted June 8, 2015 Share Posted June 8, 2015 Dang! I should have slipped in "probably is an A1 individual". (You are very alert for a Monday morning!) Donna David Saikin, Malcolm Needs, mollyredone and 3 others 6 Link to comment Share on other sites More sharing options...
Malcolm Needs ☆ Posted June 8, 2015 Share Posted June 8, 2015 Ah Donna, but it Monday evening here - and I've got to stay alert as Dee (my wife) has gone to A&E having sliced the top off her index finger in the kitchen (looks like a killing field out there at the moment), and so I am waiting up to see how she is. Good job she'd finished cooking dinner first!!!!!!!!!!!!!!!!!!!!! AuntiS 1 Link to comment Share on other sites More sharing options...
tbostock Posted June 8, 2015 Share Posted June 8, 2015 Oh no...hope your wife is OK, Malcolm. And I hope for your sake that she does not EVER see your comment about your dinner. Ensis01 and CMCDCHI 2 Link to comment Share on other sites More sharing options...
Malcolm Needs ☆ Posted June 8, 2015 Share Posted June 8, 2015 Yes thanks Terri, she's back home now and feeling fine - although I suspect that once the shock wears off, it will be mighty painful. Have no fears for me - she will never read the post about the dinner. If she does, PathLabTalk will have one less member!!!!!!!!!!!!!!!!!!!!!!!!!!

ANORRIS Posted June 9, 2015 Share Posted June 9, 2015 Ah Donna, but it Monday evening here - and I've got to stay alert as Dee (my wife) has gone to A&E having sliced the top off her index finger in the kitchen (looks like a killing field out there at the moment), and so I am waiting up to see how she is.

Malcolm Needs ☆ Posted June 9, 2015 Share Posted June 9, 2015 Thanks everyone for your insight! Malcolm, do you see any clinical benefit to testing the patient's plasma with commercial A2 cells. Quite frankly - No!!!!!!!!!!!!!!! Link to comment Share on other sites More sharing options...
CMCDCHI Posted June 9, 2015 Share Posted June 9, 2015 The only time I have ever known of A subgroups to matter is when they cause a type discrepancy or in the case of kidney transfusion. I remember doing anti-A1 titers on a potential kidney recipient to see if the subgroup recipient could tolerate an A1 donor. Link to comment Share on other sites More sharing options...
