Samples collected for ancient DNA (aDNA) need to be handled with great care. Radiography, fluoroscopy, or CT scan should be used to verify precise sampling site location. Additionally, sterile technique should be maintained. The VE is best used to visualize the target location with the sampling tool being introduced from another point of entry into the field of view, as in a laparoscopic procedure. Sampling tools for specimens intended for aDNA analysis should be instruments with a sheath or outer housing into which the sample can be retracted to protect it from contamination upon removal.
