There are many methods to freeze and mount specimens in the Mohs lab, but what is the most accurate and precise embedding method?
In this video a sample of tissue was sectioned off at 6 microns. The sample was harvested on a slide and then re-embedded using the True Margin device. The device aligned the sample so precisely that the technician was able to re-harvest the sample in two cuts. It took 2:09 minutes from the time the sample was harvested to the time a full section was re-harvested.
Why does precision matter? Because for every single micron faced-off the block, the chances of the patient undergoing an additional unnecessary surgical procedure is increased. Meaning a larger suture size or larger scar or unnecessary repair.
Next time a case result is positive ask yourself "was it truly positive or could I have been more precise and help avoid unnecessary procedures?"
