2004年12月2日 · Anti-A1 is the same as most examples of anti-N, -P1, -Lea, etc. If non-reactive at 37C, crossmatch-compatible RBC can be issued and antigen-negative units are not required. Cases of hemolysis caused by anti-A1 produced by A2/A2B patients exist but are rare.

2016年1月8日 · In this scenario we would set up A1 cells, A2 cells and group O screening cells as well as a patient auto control and incubate all at Room temp. Occasionally, an antibody other than anti-A1 (e.g. cold auto antibody, anti-P1 etc.) will be reacting with reverse grouping cells.

2017年11月27日 · I would also think of resolving ABO discrepancy. If there is Anti-A1 in your patient's plasma, then you have to find type A red cells negative for A1 antigen. In my opinion, it is easier and more practical to use the reagent A2 cells. You have to consider the cost of Anti-A1 lectin and resources used to find A1 negative cells.

2015年10月7日 · I would advise giving cross-match compatible units of group A, whether they be A 1 or A 2 (or any other subgroup of A), unless the anti-A 1 is of the very rare type that reacts strictly at 37 o C, as this is the only kind of anti-A 1 that may be clinically significant).

2017年2月27日 · Well, unless the anti-A 1 really is one of the exceedingly rare clinically-significant ones, reacting at STRICTLY 37 o C, the donor does not have to be group O - indeed, unless the anti-A 1 does come into this incredibly rare type, you can …

2014年8月10日 · Anti-A: 4+ , anti-B: 4+, anti-A1 Lectin: 0, A1 cells: 3+, B cells: 0, A2 cells: 0; DAT: neg; antibody screen: neg. I am wondering if this patient is a real group A2B as I thought usually A2B is only 2+mf with anti-A and 1+ with A1 cells. Patient has no history of BMT, but has liver and kidney failure.

2012年11月2日 · In the case of Anti-A1 lectin reagent, the purpose of the controls are to demonstrate that the reagent can correctly distinquish between A1 and A2 cells.. In a facility where appropriate controls cannot be tested and the test is being done to resolve an ABO discrepancy in a patient who may require blood transfsion, one could make a case for ...

2012年12月7日 · a) report the antibody as Anti-A1 (if it reacts at 37C, it is 'clinically signficant') for now. give him O cells for the next few months to eliminate the confusion. c) if this patient continues to have a positive IgG-DAT due to Anti-A1 after all those A1 cells are out of his system, then I'd change it to an auto-antibody and transfuse accordingly.

2010年4月30日 · Anti-A1 almost always falls into the category of being clinically insignificant. That having been said, it is almost impossible to persuade some people that this is the case. Amongst those who are difficult to persuade, it would seem to me, are the renal transplant surgeons.

2024年9月25日 · ABID- Anti-M and inconclusive. Before getting the absc result.. my tech decided to work on the extra reaction backtype discrepancy thinking that it's a subgroup.. anti-A1 lectin was negative and RT tube screen was positive at IS.
