AB The  Gram  stain  is  used  to  rapidly  identify  organisms  in  a  patient  specimen  and  classify  them  as  either  gram-positive  or  gram-negative.  This  assay  can  identify  in  minutes  a  pathogenic  organism  if  it  is  present  in  sufficient  number  and  the  test  is  performed  correctly.  This  test  requires  microscopic  examination  of  a  stained  slide,  and  recognition  that  gram-positive  organisms  are  purple  and  gram-negative  organisms  are  red.  The  specimen  from  a  patient  which  may  contain  pathogenic  organisms  is  applied  to  a  glass  slide,  and  then  fixed  and  stained  in  a  series  of  steps  that  ultimately  leads  to  the  differential  staining  of  gram-positive  and  gram-negative  organisms.
