Dna Paternity Testing: Submitting Non-Standard Samples

 - by admin

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.
