Identity testing, formally DNA identity testing, is often seen on TV shows. It is used in forensic pathology and surgical pathology.
Technique
- Looks for short tandem repeats in non-coding regions of the genome.
Uses
- Tissue floater.[1]
- Suspected specimen mix-ups.[2]
- Decendent identification - uncommonly used, despite the impression one may have from TV shows.
- Chimerism analysis - post-bone marrow transplantation.[3]
