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 collection tube of swab with the code "Sample 1" and the sampling date.

Step 2
Carefully open the first collection tube by holding the red plastic handle end and carefully remove the sterile swab for buccal cell collection.

Step 3
Sampling: Holding the red plastic handle end of swab, place the cotton tip of the swab inside the cheek and rub it firmly in every direction several times (20 seconds in each cheek). Repeat steps 1-3 with the second collection tube with the code "Sample 1".

Step 4
Air dry the swabs for at least 3 hours (no less) at room temperature while keeping them protected from any source of contamination. When dry, place the swabs back in the collection tubes.

Step 5
Place the two collection tubes containing the biological material to be analyzed in the reply envelope and send it back to DNAlogy along with the completed Consent Form.


BLOOD STAIN PATTERN ANALYSIS

During bloody events, traces of blood are deposited on various surfaces such as walls,  furniture, people, clothes, etc.

Blood stain pattern analysis is the science that studies the form and distribution of blood traces in  order to determine the mechanisms of origin.

Blood stain pattern analysis allows for:
1) the representation and identification of events (chronology of events, the nature of the  weapon used, the number of hits)
2) identification of the positions of the people present in the field (victims)
3) the checking of the compatibility of testimonies
4) a more objective selection of suitable traces for genetic analysis


DNAlogy’s experts, members of IABPA (International Association of Bloodstain Pattern Analysts), offer for the first time in Greece, a service for the analysis of blood traces.
