AB Modern  medicine  relies  extensively  on  the  clinical  laboratory  as  a  key  component  of  health  care.  It  is  commonly  held  that  at  least  60–70%  of  all  critical  clinical  decisions  rely  to  some  extent  on  a  laboratory  result.  For  many  diseases,  the  clinical  laboratory  provides  essential  diagnostic  information.  As  an  example,  histopathologic  analysis  provides  basic  information  about  histologic  type  and  classification  of  tumors  and  their  degree  of  invasion  into  adjacent  tissues.  Microbiologic  testing  is  required  to  identify  infectious  organisms  and  determine  antibiotic  susceptibility.  For  many  common  diseases,  expert  groups  have  produced  standard  guidelines  for  diagnosis  that  rely  on  defined  clinical  laboratory  values,  e.g.,  blood  glucose  or  hemoglobin  A1C  levels  form  the  basis  for  diagnosis  of  diabetes  mellitus;  the  presence  of  specific  serum  antibodies  is  required  for  diagnosis  of  many  rheumatologic  diseases;  and  serum  levels  of  cardiac  markers  are  a  mainstay  in  diagnosis  of  acute  coronary  syndromes.
