Clinical Guide: Toluidine Blue Dye

leave a comment »

Over the last couple weeks I’ve received several questions related to using Toluidine Blue dye in sexual assault medical-forensic exams, so I figured it was time to put together a clinical guide on the topic.

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.

Comparison of methods for identifying ano-genital injury after consensual intercourse. (Zink, et al., 2009)

Validation set correlates of anogenital injury after sexual assault. (Drocton, et al. 2008)

Significance of toluidine blue positive findings after speculum examination for sexual assault. (Jones, et al., 2004)

Signs of genital trauma in adolescent rape victims examined acutely. (Adams, et al., 2000)

Use of toluidine blue for documentation of traumatic intercourse. (Lauber & Souma, 1982)

Books

Some of the textbooks make mention of TB dye and its application. I’ve included links to them via Google Books. Just like with the research articles, read with a critical eye–I’m not endorsing any particular textbook, just giving you the particulars of where to find the information.
