Seznam normálních laboratorních hodnot převzat z www.coursewareobjects.com/objects/evolve/E2/pdf/SD_Quick_Reference_Tool… a www.student.med.umn.edu/wardmanual/normallabs.php
Ačkoli máte během zkoušek USMLE Step 1 a Step 2 CK seznam normálních laboratorních hodnot k dispozici na počítači, je výhodné je umět zpaměti. Ušetříte si tím spousty času a stresu.
