If you intend to take a paternity test or other relationship DNA testing, the following article gives you all necessary information on how to proceed to collect samples of your test.

The purpose of the exercise is to obtain samples of cheek cells from which scientists at the laboratory will extract DNA to examine and identify genetic relationships. To do this you will need to take with buccal swabs samples from those concerned to know the mother, father and child in the case example of traditional paternity test. Do not worry – it is not at all painful and the process is very simple and concise.

Before the start, we recommend that you ask all those involved in DNA test not to eat and drink at least 30 minutes before giving their samples, in order to avoid contamination of the sample that could negatively influence the test. It is also recommended not to smoke one hour before taking samples for DNA testing.

The samples once collected must be clearly marked indicating the names and roles of people involved on the envelope and the form supplied with the kit DNA sample. Samples of each person must also be stored separately to avoid any risk of contamination that could negatively influence the results of DNA testing. The envelopes are usually provided with color coded to help differentiate them. Carefully remove the samples is crucial for a reliable test for it is strongly recommended to carefully follow the instructions in the kit DNA sample.

The collection of samples you have in fact two rods per person buccal sample to allow all goes well if one fails. With cotton swab isolated from any contact that may contaminate the DNA, rub against the inside of the cheek to collect saliva and cells that contain DNA. Also in isolating the piece of cotton stem any possible infectious agent, let dry for about 60 minutes before sending to the laboratory. Follow the same process with the stems of sampling for all persons involved in paternity testing.

Once the samples are collected and filled the forms, you can send your package to the lab to conduct DNA testing. It is generally recommended to send DNA samples by mail as recommended to ensure their receipt by the laboratory.

You can get wherever you are on your DNA test results, which may take several days or weeks depending on the test chosen.

However, there are cases where the alleged father is unavailable for testing since died. Many believe that in such circumstances there is no solution to this problem and authorship can never be established conclusively.

In reality, there are a number of options available to confirm the identity of the father. One of them is the relationship of DNA testing, which is similar to test DNA paternity test but requires immediate members of the family to confirm the different types of relationships. Tests can be made between siblings, uncle / aunt and niece / nephew and grandparents. These tests are not the subject of this article but are worth being explored as options if the father is not available for testing.

In case of death, we will explore three possible scenarios and what should the client:

Case 1: If the person has just died and it is still possible to obtain biological material from the body (usually the period not exceeding one week after the death), it is recommended that the client tries of obtain (if possible) samples of hair with the root and also fingernail clippings. A technically qualified laboratory should be able to extract DNA from these samples and used for the comparison of paternity.

Case 2: In cases where the body was already buried, samples can be obtained in an indirect way – for example with a toothbrush, comb (might contain useful hairs), dentures or cigarettes were smoked recently. It is likely that all these samples contain substances that DNA can be used for testing. However, success in obtaining DNA from such samples depends on a number of factors and most importantly the state of the sample and the amount of DNA it contains (eg cigarette smoke completely against another relatively unused.)

Case 3: In cases where the body was buried for a number of years, and samples available are skeletal remains, it is recommended that a bone fragment from the axis of the femur and / or l ‘humerus weighing approximately 2 grams and / or two teeth per individual are obtained.

The options mentioned are some among many other available. The important thing is to get a sample from the deceased which may contain DNA. Naturally the costs and difficulties to obtain will be relatively higher than just getting some hair or nails of the body (for example 3 by the body require exhumation). However, each case has its own details and it is always advisable to seek advice from an expert in this field (eg forensic) or company who will solicitée to the test.
