Nugent score

The Nugent Score is a Gram stain scoring system for vaginal swabs to diagnose bacterial vaginosis. The Nugent score is calculated by assessing for the presence of large Gram-positive rods (Lactobacillus morphotypes; decrease in Lactobacillus scored as 0 to 4), small Gram-variable rods (Gardnerella vaginalis morphotypes; scored as 0 to 4), and curved Gram-variable rods (Mobiluncus spp. morphotypes; scored as 0 to 2). A score of 7 to 10 is consistent with bacterial vaginosis without culture. The Nugent Score is now rarely used by physicians due to the time it takes to read the slides and requires the use of a trained microscopist. Bacterial vaginosis diagnosis is done by evaluating the pH, the presences of Lactobacillus spp. versus a mixed flora consisting of Gardnerella vaginalis, Bacteroides spp, Mobiluncus spp, and Mycoplasma hominis. Nugent's test for bacterial vaginosis is performed by measuring the pH, evaluating the presence of clue cells, white discharge an odor of amines after mixing with KOH. Prior to the development of Nugent's test, assessment of bacterial vaginosis was based on culturing G. vaginalis, examining a gram stain of vaginal discharge and gas chromatography.Lactobacillus morphotypes — average per high powered (1000× oil immersion) field.
