Accurate diagnosis of Bacterial Vaginosis is important because its symptoms can resemble those of yeast infections and sexually transmitted infections, which require different treatments. Gynaecologists use a combination of symptom assessment, pelvic examination, vaginal pH testing, and microscopic evaluation of vaginal fluid to establish the diagnosis. Timely treatment helps relieve symptoms, prevent recurrent infections, and reduce the risk of complications, particularly in pregnant women and those undergoing gynaecological procedures.
