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.

FAQ
Why should I choose DNAlogy laboratories?

• QualityDNAlogy laboratories are accredited by the Hellenic Accreditation System ESYD according to ELOT EN ISO/IEC 17025:2005 quality standard and certified by the International Organization of External Control GEDNAP and the International Society for Forensic Genetics (ISFG) for the validity of the DNA analysis results.

• High Standards: All procedures that take place at DNAlogy laboratories are automated and are performed with robotic systems, minimizing the “human error” factor and providing quick, reliable and inexpensive analyses. Our administration and laboratory staff, has done postgraduate studies (MSc or/and PH.D.) so that you can be sure that your samples are handled with responsibility and scientific specialization inside and outside of the lab

• Discretion and Confidentiality: At DNAlogy, all analyses are performed with discretion and results are absolutely confidential. When samples arrive, they are given a unique barcode that follows them throughout the analysis, maintaining complete anonymity.

• Saliva sampling: Collection of biological material is done through rubbing of the inside of the cheek with special sterilized buccal swabs. In contrast, to blood sampling which is a painful and invasive method, saliva sampling is a simple, quick, painless and non-invasive procedure.

• Reliability: The validity of our results is 100%. By using 17-24 internationally certified genetic markers for all the analyses and performing every stage of the analysis process based on the international standards and rules we guarantee that the results you receive are completely trustworthy.

What is a Genetic Identity?

Each person’s DNA is the basis of his existence, the program to be followed for creation of life…

Each person’s DNA is unique and distinguishes him from everybody else. Between our genes that code for all our characteristics and are alike between humans, there are non-coding regions that do not code for any information and that show high levels of polymorphism. By studying 16 – at least- such regions, we can create a person’s “Genetic Profile” that offers uniqueness on earth.

*These domains should be internationally certified.

How many types of paternity test are offered at DNAlogy and what is the difference?

DNAlogy gives you the opportunity to perform 2 different types of quick and accurate paternity testing:

Paternity testing for personal reason when someone seeks genetic proof of paternity of a child. Saliva sampling can be performed at DNAlogy laboratories from our staff or you can do the sampling yourself at home since it does not require specialization. Mother’s participation is recommended but optional. You can find the saliva sampling DNAlogy-Patrotis-kit® in your nearest pharmacy.

Paternity testing for legal reason to prove paternity or non-paternity. Saliva sampling must be performed by our DNA Experts or by a certified third party (lawyer, doctor, scrivener etc) and requires participation of the mother in case the child is not an adult. DNAlogy can represent you in Greek and European court if needed thanks to the international scientific team of experts.

How is DNA used for proof or exclusion of paternity?

Each person inherits 50% of his DNA from his biological father and 50% from his biological mother. For each genetic marker that is analyzed, each person has 2 copies (alleles) one of paternal and one of maternal origin. If during analysis, the child shows alleles that are not found in the father’s DNA, then paternity is excluded 100%. If during analysis, the child shows alleles that are also found in the father’s DNA, then probability of paternity is mathematically calculated based on the frequency of the particular alleles in the general population and is practical proven when probability reaches 99.99%.

How safe are the results?

The validity of the results at DNAlogy is 100%. We use 16-23 internationally certified genetic markers for all the analyses and every stage of the analysis process follows strictly the international standards. This is our guarantee that the results you receive are completely trustworthy.

How can I get the DNAlogy-Patrotis-kit ® for saliva sampling?

There are three (3) ways to get the DNAlogy-Patrotis-kit®:

1. Find the Nearest Pharmacy of our network that sells the kit.

2. Visit DNAlogy laboratories at 98 Vouliagmenis Ave, Glyfada, to take the kit and discuss with our DNA experts.

3. Order the kit by telephone or by filling the on-line order form.

Saliva sampling procedure is simple, quick, painless and non-invasive. Each packet contains swabs for 2 persons. For more information, click here.

 

Is blood better than saliva?

Until today, people tend to believe that blood analysis is more reliable for DNA testing. This is mistakenly spread because of the use of blood in medical diagnostic testing. Αll human cells (except red blood cells that do not have a nucleus), contain the same genetic information. Blood, saliva or any other human tissue (nails, hair roots etc.) or human body secretion, can lead to a trustworthy DNA test result.

Advantages of using saliva: At DNAlogy we have developed and use a novel protocol of DNA extraction from saliva samples. In this way, we offer a procedure that is simple, quick, painless, non-invasive, with easy sample transportation (by post) and conservation (>20 years, room temperature). Saliva sampling does not require specialized staff and can be performed by the participants at their place.

 

Is there a time limitation from the day a sample is collected until the day it becomes analyzed?

In general, there is no time limitation from sample collection to analysis, as long as the basic collection guidelines are followed. Try to avoid contact with the samples in bare hands and keep all samples away from sun exposure, high temperatures and moisture. For wet samples, either follow a drying procedure or keep refrigerated. For more information regarding sampling procedure please click here or contact our DNA Expert team.

For how long can a sample be safely stored?

There is no time limitation if the sample has been stored in the appropriate conditions. In general, samples shouldn’t be exposed at the sun or high temperature/humidity.
Especially for saliva storage at DNAlogy we use the FTA cards where DNA can be conserved for up to 20 years.

 

Is mother’s participation necessary in a paternity test?

Participation of the mother does not change the result of a paternity test but raises the accuracy of the result. This happens because the child’s DNA can be precisely attributed to both parents instead of 50% identification in case of a motherless (child-father) paternity test. In legal paternity testing, participation of the mother is highly recommended while in personal paternity testing participation of the mother is also recommended but optional.Yes. As long as there are personal items of the father, on which we can detect genetic material. Such items can be a toothbrush, hair with the roots, notes, clothes or underwear that has been worn, teeth, bones etc. Avoid any contact with the items in bear hands in order not to leave your DNA on them.
