    2nd ABO

    We have been doing second ABO/Rh types on transfusion candidates with no previous history since 2002! We use previously drawn hematology specimens whenever possible. Since nursing does some of our draws, we send a small pink top tube to the floor to be used (we are the only department allowed to order and use these tubes) for the "confirm type". We use parafilm around the cap so we can make it "tamper proof" to some extent. Before we did this step, industrious people would draw two tubes at the same time and save one, waiting for our request of a second draw. They would pour over the saved tube into our special tube....now they can't. We do second types on all ABO types, we don't exclude type O.....they too can be WBIT.....which could affect other lab departments.....we let them know if we find mistypes. We also don't exclude emergency transfusion......that is when the most errors happen because people seem to lose their minds in high stress situations. We stick with type O until the confirm type has been drawn. We tried the two signatures on the tube route, but found they were just grabbing anyone and having them sign the tube whether they witnessed the draw or not. Fun times in the blood bank! :)

    2nd ABO

    We test any sample that meets the manufacturer's specimen requirements and ours are more than 24 hours. We even validated citrate tubes so we could use them for blood types. I'm comfortable with getting a second draw on only non-O patients because we also have a BB banding system and an electronic patient ID system. The problem is the rogue humans who decide to make end runs around the systems but with belts and suspenders and duct tape, I feel pretty confident. We are also lucky in that we do the prenatal testing for most of our OB patients. That's a point to consider in making the determination of how many specimens you will have to collect.

  3. And Admissions sometimes selects the wrong patient's record to admit--usually someone with the same name. You would hope that we have enough checks to catch this pretty quickly these days, but strange things happen.

    Yes, I rather thought so, so it was more likely to be evidence of a weak anti-G in the polyclonal anti-D, than a genuine anti-C (particularly as most anti-C reagents, including monoclonal reagents, believe it or not, are actually anti-Ce, rather than a pure, monospecific anti-C). Thank you for your reply.

  5. Of course. There is no link between a previous admission and a current one that is reliable enough to allow for transfusion of any product without at least confirming the ABO/Rh. We have even had a few patients who have been admitted with a friend or relative's ID in order to piggy-back on insurance! Scott

  6. It is, nevertheless, true. Thorpe SJ, Boult CE, Stevenson FK, Scott ML, Sutherland J, Spellerberg MB, Natvig JB, Thompson KM. Cold agglutinin activity is common among human monoclonal IgM Rh system antibodies using the V4-34 heavy chain variable gene segment. Transfusion 1997; 37: 1111-1116. Thorpe SJ, Ball C, Fox B, Thompson KM, Thorpe R, Bristow A. Anti-D and anti-i activities are inseparable in V4-34-encoded monoclonal anti-D: the same framework 1 residues are required for both activities. Transfusion 2008; 48: 930-940.
