Dating of wounds
Certain tests can be done to date wounds.
However, wounds change over time and there can therefore be a significant
overlap, so that dating may not be absolutely conclusive. Wound changes are due
to the tissues' response in trying to heal the wound.
The following is of importance in dating of
Macroscopic appearance, in other words colour changes, swelling, et
cetera, as seen with the naked eye.
Microscopic appearance, in other words cellular changes in the form of
inflammatory cells and connective tissue elements, visible under a microscope.
Biochemical analysis, for example to detect enzyme changes. This is a
highly specialised field and it is seldom used?
