Our SP platform now offers an automated Gram stain
in addition to sample concentration, purification and homogenization with second- to-none performance.
When the aerobic or anaerobic bottle was identified as positive, a Gram stain

Urine Gram stain
is not a routine study done in our institution, but it may be warranted in this subset of patients to aid in the work-up of UTI," Dr.
