|Additional information||STAT Gram stains are read by Hematology at Moffitt-Long and by Mount Zion Laboratory.
STAT Gram stains are done on normally sterile site only.
Normally sterile site specimens include CSF and other sterile body fluids (e.g. vitreous, pleural, peritoneal, ascites, amniotic, or joint fluids, bile, dialysates), sterile body tissues, and other specimens from specialized invasive procedures (e.g. bronchoalveolar lavage), and transfused blood product in the case of a transfusion reaction
