DNA Testing and Sampling Guide
Background
DNA is contained in the root of the hair, not in the shaft itself. It is therefore essential that the hair roots (which are clearly visible as bulbous protrusions) are attached to the plucked hairs submitted for DNA analysis.
Sample
It is important that hairs submitted for DNA analysis are clean and dry. Moisture, combined with faecal contamination, degrades the DNA, impacting on our ability to obtain a result.
| 1) Select 10-20 tail hairs and pluck with a rapid sharp motion. Repeat the procedure to obtain about 30 to 40 hairs. |
|
2) The hooked or bulbous hair roots plucked from under the skin should be clearly visible. |
|
| 3) If the samples are contaminated with faeces, trim the distal end (opposite end to the bulbs). Place the hairs in a pbb DNA envelope which should be labeled with the unique identity of the subject from which the sample was collected. |
