Thanks to the latest advances in technology and the emancipation of some of the laboratories, tests for genetic are now accessible to all.
Well-known to the public, the paternity test (in order to find the biological father) is now very widespread.
The maternity test, for its part, deserves a bit of lighting :
In what cases does it is a maternity test ?
This dna test between the breeder female and the child is asked when there is a doubt about the relationship. This doubt can provide in case of any suspicion of exchange of infant at birth, in the case of adoption (child in search of his mother or, conversely, a mother wishing to find a child), in the case of in vitro fertilization (donor egg / oocyte), or simply a separation, loss of a view for a long period of time.
It may also be asked to do the test in some process of naturalization or family reunification.
How is this dna test for parentage ?
The dna represents the genetic heritage which is given to us by each of our two parents. Thus we inherit a part of the dna of our mother and part of the dna of our father. This combination makes us unique and differentiated.
During the dna test, we compare what is called the “profile” genetics of each of the two persons to :
- exclude the possibility of parentage
- either prove parentage with a high similarity
This genetic profile is built from a number of DNA markers. In fact, it would be tedious to sequence the entire genome of the two participants in the test. Establish a profile from a number of markers sufficient to establish a statistical evidence : if a large number of markers is different, we may exclude 100% of the relationship. On the contrary, when the relationship is established, it is with high precision, greater than 99%.
The realization of the test: simplicity and efficiency
In spite of this, a large number of people consider, take a sample DNA is not complicated, it is actually very simple.
Zero obligation to physically go to a lab to do it, just have a DNA kit. You will then be asked to take a sample ( saliva or cheek cells). To do this, simply rub the inside of your cheek with the swab provided. It is a process completely painless.
To perform the test it will be necessary, therefore, to provide a sample of the child as well as a sample of the alleged mother. This implies the acceptance of the two donors involved.
The samples are then sent to the testing lab maternity dna analysis, and the results will be provided confidentially.
You must, therefore, remember that a maternity test is simple to implement and fast to analyze. And the reasons for which you need to perform are quite serious and real.
