  1. Incubating patient plasma with patient red blood cells and then applying the antiglobulin test is no longer a Direct Antiglobulin Test but an Autocontrol test which is an Indirect Antiglobulin Test. Some may think an Autocontrol test gives the same results as a Direct Antiglobulin Test, but that is not always true.

  2. No guidelines, just clinical common sense. There are absolutely no data to support the need for excluding heterozygous donors, nor the need for heterozygous recipients to receive only AA blood. Heterozygous patients are physiologically normal except for some data to suggest that under extreme conditions of dehydration, altitude they are slightly more susceptible to complications that occur even among hemoglobin AA patients.

  3. We have been AABB since the 70's. My manager dropped it last year. He dropped CAP also. We are just Joint Commission.

  4. Based on an observational study of ABO grouping in Gel I reported at the 1997 AABB Annual Meeting, ABO Plasma Grouping discrepancies occurred in 0.8% (26/3183) adult ABO grouping tests in Gel. Anti-B was not detected in 24/26 patients, anti-A was not detected in 2/26 patients, and anti-A1 was not detected in 3183 patients. In comparison, anti-A and anti-B was detected in 19/26 patients by the immediate-spin tube test, and was detected in 7/26 patients after 10 minute incubation room temperature incubation and centrifugation. Based on this study and 20 years of gel testing since that time have shown me the anti-A1 is rarely detected in Gel and that 70-80% of ABO plasma grouping discrepancies are resolved using the immediate-spin tube test. Centrifugation is used quite differently in gel versus tube testing. Centrifugation is used to separate agglutinated cells from un-agglutinated cells within the gel column, but is used to enhance agglutination in standard tube tests by forcing cells together at the bottom of the tube. This may contribute to the increased sensitivity of tube testing in ABO Plasma grouping tests.

  6. I agree with David and would not bother with the expense of AABB accreditation.

  7. It used to be that AABB accreditation meant you achieved a level of sophistication encompassing Quality System Essentials. Today, I am not certain that is the case. CAP has deemed status and has upgraded their standards to be at least as stringent as AABB's (some are even more so). Probably the only selling point are the CE materials and the national meeting every year. Hospitals I have worked in have all been AABB accredited. My current employer, we dropped AABB about 15 years ago because there wasn't any bang for the buck to be accredited by them. This was my decision - was an AABB member and assessor/inspector for 20+ yrs.
