Routine results are reported within 8 hours of receipt in the Laboratory
Gram stain results are dependent on the morphology and Gram reaction of organisms and amount of inflammation present. The gram stain is assessed using the Nugent scoring system.
Microscopic examination of a stained specimen and use of Nugent scoring of organisms observed.
Indicative of bacterial vaginosis based off of the gram stain using the Nugent scoring system of relative amounts of microbial morphotypes. It can provide rapid presumptive diagnosis of infectious agents and also be used to assess the quality of clinical specimens.
The Gram stain is the most basic stain in bacteriology, delineating major structural and taxonomic groups of organisms. The Nugent scoring system is the definitive laboratory method for diagnosis of bacterial vaginosis (BV) in women of childbearing years and post-menopausal women on estrogen replacement therapy. It can also aid in the diagnosis of vaginitis.
