AB Sensitive  and  specific  laboratory  tests  and  imaging  studies  are  essential  to  accurate  diagnosis  in  many  clinical  settings.  Proper  use  of  the  laboratory  and  imaging  requires  accurate  clinical  hypotheses  generated  at  the  bedside.  Laboratory  tests  and  imaging  provide  reliable  and  valid  answers  to  well-conceived  clinical  questions.  They  are  also  liable  to  overinterpretation  and  can  be  quite  misleading  if  not  interpreted  in  the  clinical  context  as  answers  to  specific  questions.  Beyond  a  few  screening  tests,  these  studies  should  be  used  to  test  the  physiologic  and  diagnostic  hypotheses  generated  during  the  history  and  physical  exam.  The  laboratory  and  the  radiology  suite  are  not  the  places  to  look  for  ideas;  they  are  the  places  to  test  hypotheses.  If  you  are  unable  to  generate  testable  hypotheses  after  the  history,  physical  exam,  and  screening  tests,  it  will  be  more  useful  to  seek  consultation  than  to  begin  an  undirected  series  of  laboratory  and  radiologic  studies.  A  full  discussion  of  the  proper  use  of  diagnostic  tests  is  beyond  the  scope  of  this  text.
