lOMoARcPSD|3920845Common Laboratory Values Cheat Sheet
Diagnostic tests are crucial in any aspect of clinical practice since they assist clinicians in establishing and determining the particular
condition of the patient. Nurses are often tasked of patient preparation and specimen collection during these diagnostic procedures.
It is of utmost importance that nurses are knowledgeable about the different procedures and their values and results to make
informed clinical decisions. To assist nurses, here are the common laboratory values listed in an organized and easy-to-understand
table.
