DNA test is the most reliable test that can confirm (99.99 percent) or exclude (100 percent) paternity. The paternity test, based on a genetic test, compares samples of genetic material taken from the father and the child. What exactly is the paternity test? How much does such a DNA test cost?
Paternity testo, based on geneticDNA test , i.e. an analysis of a chemical substance in which an individual is writtengenetic codepassed on to the child by biological parents, it gives 100% certainty when investigating paternity.
Paternity test: what is needed for genetic DNA testing?
A hair (preferably with a root), a piece of a nail, a fragment of the epidermis or a bit of any secretion is enough to carry out genetic DNA testing. In the investigation of paternity, blood drawn from the child, mother and alleged father is most often used. An equally reliable test can be performed by collecting a mucosa fragment from the inside of the cheek.
Properly performed genetic DNA testing is tedious, requires the use of complex equipment, sterile conditions and time. You have to pay about PLN 2,000 for them. For comparison - serological blood analysis costs 700-800 PLN. Each group of samples is tested and evaluated in two or three times to avoid error. After the samples are marked in the laboratory, DNA isolation begins. The obtained results are provided to the interested parties in a form agreed with them in advance, e.g. by phone after entering the password.
For the court, in paternity cases, the results from the facility certified by the Forensic Hemogenetics Committee of the Polish Society of Forensic Medicine and Criminology are reliable. The sample must be taken by an authorized person in the presence of parents. It is necessary to draw up a protocol. In support court cases, tests are often done without the mother's participation.
How is DNA genetic testing done?
The genetic material is treated with reagents that dissolve cell membranes and release DNA. Then, in special centrifuges, it is separated from the remaining parts of the cells and collected on a special membrane. This is pure DNA of the test person. Then the properties of the multiplied material are marked.
