Nugent score



In 1981, Nugent et al. described a Gram stain scoring system of vaginal smears 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 (G. vaginalis morphotypes; scored as 0 to 4), and curved gram-variable rods (Mobiluncus spp. morphotypes; scored as 0 to 2) and can range from 0 to 10. A score of 7 to 10 is consistent with bacterial vaginosis. Nugent score is a tool in the study of vaginal eco-organ.
