DNA Testing Resources
Non-standard samples
There are certain cases where it is not possible to collect a cheek swab from the party to be tested. However since the DNA is the same in virtually every cell in the body, it is possible to obtain DNA from other sample types. In our laboratory, we refer to any non-cheek swab sample as a non-standard sample.
Chain of Custody
For any Legal DNA case, the Chain of Custody of the sample is of utmost importance. Therefore Orchid Cellmark has developed strict procedures and systems to ensure that the procedures have been followed.
Chain of Custody involves procedures that apply to the following steps of a DNA test:
- Identification of the tested party
- Obtaining Consent
- Collection of specimens from the tested party
- Packaging of the specimens
- Shipment of the specimens
- Receipt of the specimens by the DNA laboratory
- Transfer of specimens within the DNA laboratory
- Storage of the specimens
