What This Book Owns, and What It Sends You Elsewhere For
A legend board: a three by four grid of token chips, each a solid square over its soft fill with the label in mono beneath, the watch chip carrying a hooked arrow and the words SHIFTED IN BOOK 7, and three device miniatures at actual size below the grid, a critical flag breaking a panel edge, a three point trend arrow, and an unticked box.

Legend
- ok normal, or the target you are driving toward
- watch abnormal, monitor and trend. In this book only, the watch swatch is shifted off the topic color so it is never confused with the amber used for headings.
- crit critical, stop and call
- flag device a critical marker that breaks the panel edge, used only where delay causes harm
- trend arrows a three-point set showing rising, flat, and falling
- tick box an unticked square you fill in when you can do the thing unaided
Margin notethey test the call, not the cutoff.
Disclaimer: Reference ranges vary between institutions and between reference laboratories. Answer exam items from one canonical source and practice to local protocol. These books are exam preparation, not clinical decision support.
Takeawayif the question asks what the value means for the patient's disease, that answer is in another book. If it asks what the value is and what you do about it, it is here.
