Workup: the contaminated draw

One specimen, four stations. QC is in control, yet a basic panel from 4 North does not fit its patient. At the run review you find what got into the tube, you call the nurse for a new specimen, and you dilute the CK on the redraw.

Each station asks one thing, and its answer changes what the next one sees. The debrief at the end shows every decision you made on one timeline, with the lesson behind each one.
