  1. Hello! I've worked with Immucor over my entire 18 years in the BB - you should be able to reach out to your account rep for the info you are seeking regarding ABID troubleshooting. They have a collection of white papers that can help you. Regarding your Rh negative confirmation in tube - that sounds like something specific to your facility. It's not an Immucor recommendation that I am aware of, nor do we do that at my facility. The CMT plates are literally just a blank microtiter well, so the reactions are very similar to tube, and are read the same way. The trouble with the instrument reading the reactions is that it will not detect mixed field or rouleaux and can have false positives because of that.

  3. NOBODY has EVER performed either an Indirect Coombs Test (ICT) (or, still worse, an Indirect Coombes Test), or a Direct Coombs Test (DCT) (or, still worse, a Direct Coombes Test). There is most certainly NOT either an Indirect or Direct AHG Test. AHG is a reagent used in both the IAT and the DAT. The correct terminology for the former test is the Indirect Antiglobulin Test (IAT) and for the latter test is the Direct Antiglobulin Test (DAT). It is true that Coombs was the primary author on three papers describing the test1-3, but Mourant and Race were his co-authors on these papers, and they are often forgotten. Indeed, Coombs himself did not like the test being referred to as the Indirect Coombs Test and the Direct Coombs Test4, particularly as the principle of the test had been described in two papers published in the early 1900s,5, 6. 1. Coombs RRA, Mourant AE, Race RR. Detection of weak and ‘incomplete’ Rh agglutinins: A New Test. Lancet 1945, 246, 15-16. DOI: 10.1016/S0140-6736(45)90806-3. 2. Coombs RRA, Mourant AE, Race RR. A new test for the detection of weak and “incomplete” Rh agglutinins. British Journal of Experimental Pathology 1945; 26(4): 255-266. 3. Coombs RRA, Mourant AE, Race RR. In vivo isosensitization of red cells in babies with haemolytic disease. Lancet 1946; 247: 264-266. DOI: 10.1016/S0140-6736(46)91925-3. 4. Coombs RRA.
