Least invasive methods include, but are not limited to, external examination without the dissection of the body except that which is necessary for the procurement of blood or bodily fluids for toxicological or other analysis. Most invasive methods include, but are not limited to, dissection of the dead body and the examination of bone, tissue, organs, and foreign objects.
