This young physician stated that his attending physician had asked him to order a “Direct and Indirect Coombs,” and he had done so. The blood bank technologist told him that both tests had been done, but this fine young doctor couldn’t understand why there wasn’t a result in the computer labeled as “Indirect Coombs.” He said that he could accept the result called a “direct antiglobulin test,” but the technologist would not issue a report that was labeled “Indirect Coombs” (he mentioned that his attending was very demanding, and I am pretty sure that he was afraid for his life, but I may have misinterpreted the panic in his voice and the fact that I could hear his heart pounding through the phone). He somewhat forcefully “requested” that I tell my staff to issue an appropriate report. You aren’t alone, though these are two of the most mysterious laboratory tests to clinical staff, students, and less experienced laboratorians.Īnd, if you see nothing wrong with what this young doctor demanded, chances are you don’t understand the Direct and Indirect Antiglobulin tests (DAT and IAT, respectively) quite as well as you could! If you’re thinking at this point that conflict resolution training should be part of medical school curriculum, you are not alone. This post will describe the differences and similarities between the DAT and the IAT, and how each of them is used. ![]() Tuck this away as, regardless of your role in patient care, this is a question you’re likely going to need the answer to at some point. Let’s just start with the “name thing!” In my experience, most clinicians call these tests “Indirect Coombs” and “Direct Coombs,” while most blood bankers refer to them by their more proper names: “Indirect Antiglobulin Test” (IAT) and “Direct Antiglobulin Test” (DAT). That difference is where much of the confusion for clinicians arises, because while everyone is talking about the same tests, they are speaking in different dialects!īeyond dialects, though, there is a slightly longer explanation for the miscommunication frequently invoked by these two tests, and it starts with a look at the two types of immunoglobulin (antibodies) we worry about most in the blood bank: IgG and IgM. These two antibody types react in different ways with target antigens on red blood cells (RBCs). If you're not sure about any step of the process, you can check out the video below.IgG (see blue arrow in image below) is a very important antibody in the immune response, but individual IgG antibodies are hampered in interacting with RBCs (and thus being detected in laboratory testing) by their structure. As you reach the edge of your platform, just jump to the cube and it will carry you all the way to the lost villager. Shut the portal down and start chasing the flying cube. As it approaches the spikes that will destroy it, open the portal and it will make the cube take a turn to the right while you will touch the ceiling. The cubes themselves are easy to miss since they are visible only for a short period of time so just be patient and let the next one arrive. Now, do you remember the cube you rode like an elevator to get to the rotating platforms? It can be reached once you've climbed them - just go the way the game takes you and as soon as you pass the archway that attunes you to the verticality portal, you will be able to see the cube's arrival point at the bottom edge of your screen. Instead, you will know by now that opening a portal on cubes that move vertically will make them start moving horizontally. ![]() ![]() Forest's Edge Villager solutionįinding the solution to this puzzle is not with the rotating platforms or additional moves that you might obtain later in the game. The villager I'm talking about is on top of a massive spiked wall that is much taller than the rotating platforms next to it, which is the reason the peak looks unreachable. For example, the Lost Villager in Forest's Edge may look like it's glitched or impossible to reach but the trick is to have a bit of creativity and remember the previous lessons the game taught you. ![]() But it spans several biomes and hides many secrets. ![]()
