History paternity test

Thanks to the many innovations in science, a paternity test is a coherent and reliable method for the determination of the biological links. Scientists have managed many factors differ scoped accuracy of rare blood proteins to prevent blood types. Modern methods introduced testing has become a common practice for DNA paternity testing. SignificancePaternity test was created to establish a credible biological descent. This test is very beneficial for children need life support and protect of their rights. All the progress the medical world, has seen paternity tests, many changes coming to the most accurate results possible.Blood TypingIn 1920s to determine the most basic at fatherhood method was blood type in Gin. Using the system of blood type A-B-O, the protein in red blood cells a person were used to find the blood type. These proteins are inherited from the father and mother; Paternitées results are missing but precisely. Child's blood type is usually determined by the mother, blood type with no significant relationship with the father. Blood typing served only 30 percent accuracy.Serological TestThe next decade used test provide serology for paternity. This method uses the RH, Kell and Duffy blood group in serum test systems. Incompatible proteins on red blood cells are cause reactions, especially during the grafts and transfusion associated. As a result, RH, Kell and Duffy are proteins child to see who the father examined. Once again, it is for deploying only 40% accuracy.HLA TypingIt is inconclusive, until the 1970s was a more precise paternity test method was created. Conclusive results 80Prozent provided HLA typing. This time were white blood cells in particulartested on human leukocyte antigens. Children usually inherit HLA proteins of the parents, however, since HLA types shared with almost Deparents, challenge originated in the scarcity of father HLA type. Excluding the father was more difficult had two or more brothers with the same as testing by RFLPLuckily HLA type.DNA, the advent of genetic testing came in the 1980s. As fingerprints not the same for identical twins, therefore the DNA of every human being. Restriction fragment length polymorphism (RFLP) method uses enzymes mixed with purified DNA samples to fragments to create. Fragments of DNA child meets mother half and half of the father. RFLP assays proved enough boring, and the outstanding results long. However, the accuracy is placed, to 99.99 percent.DNA via PCRThe standard paternity test used create test today in the 1990s was. (PCR) DNA polymerase chain reaction analysis takes less time, with some necessary blood deal. The PCR method proved a convenient scientists and medical laboratory technicians. This is because with only a small drop of blood, DNA samples can be made. This method is now standard form of genetic tests that are used for research.
