Nugent score

From WikiMD's Wellnesspedia

Nugent Score is a diagnostic tool used in the field of gynecology to determine the likelihood of bacterial vaginosis. It is named after Dr. Robert P. Nugent, who first introduced the scoring system in 1991.

Overview[edit | edit source]

The Nugent Score is calculated based on the presence of three types of bacteria in a Gram stain of vaginal fluid: large gram positive rods (Lactobacillus morphotypes), small gram variable rods (Gardnerella and Bacteroides morphotypes), and curved gram variable rods (Mobiluncus morphotypes). The score ranges from 0 to 10, with a score of 7 or higher indicating bacterial vaginosis.

Scoring System[edit | edit source]

The Nugent Score is calculated as follows:

  • Lactobacillus morphotypes: 0-4 points (4 points for absence)
  • Gardnerella and Bacteroides morphotypes: 0-4 points (4 points for heavy presence)
  • Mobiluncus morphotypes: 0-2 points (2 points for heavy presence)

Clinical Use[edit | edit source]

The Nugent Score is widely used in clinical and research settings due to its high reproducibility and specificity. However, it requires a trained microscopist and is therefore not suitable for rapid diagnosis at the point of care.

Limitations[edit | edit source]

While the Nugent Score is a valuable tool in diagnosing bacterial vaginosis, it has some limitations. It does not account for the presence of other organisms that may contribute to the condition, such as yeast or Trichomonas. Furthermore, it does not correlate well with clinical symptoms, as many women with a high Nugent Score do not have symptoms of bacterial vaginosis.
