Clinical Guide: Toluidine Blue Dye

Research

There’s been very little written about TB dye in the peer reviewed literature over the past 30 years, so I have included all of it (that I could find) here. Some discuss the utility of TB dye in greater depth than others. As with any research, it is imperative that you read these articles (particularly the older ones) with a critical eye toward the methodology used and the relevance of their findings in light of advances in the science. All links go to PubMed abstracts.
