INSTRUCTIONS FOR BUCCAL CELL COLLECTION: DNALOGY-KIT
39352129

In the course of sampling, DNAlogy offers you free-of charge the DNAlogy-kit including the sterilized cotton swab, sampling instructions and a consent/order form for the applicant.
The aim of sampling is to collect as many cheek cells as possible and to transfer them to the sterilized cotton swab, which is going to protect DNA until its transfer to our laboratory.
Attention: Avoid any contact with the cotton tip end of the swabs.
Do not eat, drink or smoke for at least 30 minutes before sampling.
For the sampling procedure, each individual should use 2 swabs.

Step 1
Label the swabs with a unique identifying name and sampling date.

Step 2
Carefully open the sterile swab packaging holding the red plastic applicator end and remove the swab from the packaging.

Step 3
Sampling: Rub the cotton tip of the swab firmly against the inside of both cheeks several times (20-30 seconds) in each direction.

Step 4
Air dry the swabs for at least 1 hour at room temperature while keeping them protected from any source of contamination. When dry, place the swabs back in their packaging. Repeat the steps 1-4 with the second swab

Step 5
Send the swabs back to DNAlogy along with the completed questionnaire (consent and order form) by using the reply envelope.

TRACES AND FINGERPRINTS

The IGNA group belonging DNAlogy, has built a team specialized in developing and analyzing traces and fingerprints, since 2006.

We have set up networks of devoted specialists perfectly  cooperating with the genetic fingerprint teams. Due to these two  combined activities, more comprehensive services are available  within one institution, and thus, the outcomes of judicial  investigations are optimized. We offer you this double approach at  the site in Athens.

 


Methodology:

1) An expert carries out all fingerprint developments (on site or in the laboratory).
2) Our development methods have been elaborated in order to preserve the DNA and to allow all parallel or additional tests.
3) Due to the close cooperation of the experts in different activities, there are many tests that can be conducted on the same sample.
4) For ballistic tests of weapons, we have implemented a protocol together with our partner in ballistics to take over the samples.
5) We keep all other traces found during the tests (e.g., shooting residues), likely to serve further in the investigation.
6) Unique management of samples to limit transportation and handling; all being taken care of on the same site.

Advantages:

For the same sample, genetic and fingerprint tests are conducted in the same laboratory using protocols allowing preservation of both traces. This facilitates :

1) Administrative tasks.
2) Organising transportation.
3) A smaller number of interveners.
4) Optimum outcome. 

 

As far as fingerprint traces are concerned, we have invested in equipment which has allowed us to develop, acquire and preserve other invisible traces to the naked eye: Traces of pressure gradient, writing, weighing, etc.

This service is provided only if appropriate preservation is provided. It is important that it is conducted before fingerprint development.
