Day 9 🧪 Welcome back to 30 Days of ASCP: Make It Make Sense, because once you get it, you never forget it. Elution and adsorption are both used to separate antibodies from red blood cells, but they serve different purposes. Elution is used when an antibody is already attached to the patient’s red cells; we strip it off to identify what that antibody is, which is especially important in cases like positive DATs or hemolytic disease of the newborn. Adsorption is used when antibodies are free in t

Day 20🧪 Welcome back to 30 Days of ASCP: Make It Make Sense because once you get it, you never forget it. The coagulation cascade looks intimidating, but the structure is simple once you organize it. There are two pathways, intrinsic and extrinsic, and they meet at the common pathway. The intrinsic pathway begins with factors XII, XI, IX, and VIII. The extrinsic pathway begins with tissue factor (factor III) activating factor VII. Both pathways converge at factor X, which enters the common path
