AB Diagnostic  accuracy  has  been  greatly  enhanced  by  the  sensitive  and  specific  tests  available  in  modern  clinical  laboratories  and  the  rapid  advances  in  clinical  imaging.  However,  it  is  essential  to  recognize  that  proper  use  of  the  laboratory  and  imaging  modalities  is  dependent  upon  accurate  clinical  hypotheses  generated  by  the  clinician  at  the  bedside.  Laboratory  tests  and  diagnostic  imaging  can  provide  reliable  and  valid  answers  to  well-conceived  clinical  questions,  but  they  are  also  liable  to  over  interpretation  and  can  be  quite  misleading  if  not  interpreted  in  the  clinical  context  as  answers  to  particular  questions.  Beyond  a  few  screening  tests,  these  studies  should  be  used  to  test  the  physiologic  and  diagnostic  hypotheses  generated  during  the  history  and  physical  examination.  The  laboratory  and  the  radiology  suite  are  not  the  places  to  go  looking  for  ideas;  they  are  the  place  to  test  your  ideas.  If  you  are  unable  to  generate  testable  hypotheses  after  the  history,  physical  examination,  and  screening  tests,  it  will  be  more  useful  to  seek  consultation  than  to  begin  an  undirected  series  of  laboratory  and  radiologic  studies.
