Lesson 1Choosing Sample Tubes, Additives (EDTA for CBC, Glycolytic Inhibitor for Glucose) and WhyThis lesson detail the right tube types and additives for glucose and CBC tests, explaining how EDTA keep cells in good shape and glycolytic inhibitors hold glucose steady, plus tube colors, how much to fill, and common errors in picking tubes.
