As like as two peas in a house, a girl who had been separated from her sister for many years saw a girl who lived in a house. He saw a familiar book. He remembered that he had sent his sister a copy of his book. He told him that he was his sister. So he took a hair from her comb and hid it. But after going to the hospital and comparing DNA with his father, the girl was not his sister, but they were brothers and sisters. Why did the DNA authentication result like that? Is it reliable to use hair as blood certification? Is hair paternity testing authoritative or not?
As mentioned above, the man just took a hair on the comb and hid it. The paternity test sample must have hair follicles. He may take broken hair. Secondly, he cannot touch the hair follicles of the hair sample with his hands. In fact, hair paternity testing is not to analyze the composition of hair or others, but to analyze the cells in hair follicles and then compare genes. It can be seen that the paternity test of hair is still reliable, but there are many precautions. It is recommended to test the living cell tissues such as blood, cavity and mucosal cells.
What should we pay attention to in paternity testing? What are you going to prepare? First of all, of course, is the mentality. If your own flesh and blood is OK, don't be too sad and disappointed. When collecting samples, clean hands, preferably medical gloves, followed by clean envelopes. Write the names of the father and child on the envelope, put the hair with hair follicles respectively, and pull out at least 5 hairs from the hair, eyelashes, armpits, etc. This identification method is not recommended for too young children. And it is recommended to go to a regular large hospital for examination. Generally, there are identification results within two weeks.
In a word, hair can be used for paternity testing, and the accuracy is also very high.
