Independent Drug Testing and Forensic Services has a resource for a DNA lab to perform analysis for private, civil, and criminal venues. Turn around time is within 5 days under normal circumstances and paternity analysis is usually within 3 days. DNA can be found as long as there are cells available to extract the DNA. This includes things that are not commonly thought about such as latent fingerprints, cigarette butts, cups and glasses, hair follicle with the root bulb present, and much more.
The future of DNA testing is unlimited and is changing almost daily. The future holds development of testing animals, plants, and pharmaceuticals. Someday drugs can be made to the DNA of an individual to work specifically for them and created just for them.
