Mr. Nguyen Van Toan and his wife Le Thi Lan (both 58 years old, Hanoi) have two sons together named Thanh (2 years old) and Thao (34 years old). In the neighborhood, they were chosen as a model family because of their family style, happy and successful spouses and children.
Mr. Toan and Thanh both work in the field of bridges and roads but in two different agencies. They often go to supervise projects in many localities. By chance, during a business trip in Tuyen Quang, Thanh saw a person like his father carrying a basket full of food coming out of a local stall.
He silently moved closer and secretly observed. The young man was extremely surprised when it was his father. Mr. Toan walked all the way to the end of the alley, then entered a small gate. Two twin boys ran from the house to greet them, shouting loudly, "Bravo, dad is home."
Thanh was speechless. He understood that his father had another woman and children of his own.
Returning home after a business trip, Thanh did not dare reveal this secret to his mother.
A month later, he invited his father to the cafe and told him everything he had seen with his own eyes. After listening, the father was forced to bow his head and confess the whole truth.
Mr. Toan said that during a field survey 6 years ago, he met and worked with Mai - an employee of the district cadastral office. The two liked each other right from their first meeting. Mr. Toan likes her because of her quick manners, polite speech, decency, decency, and cute face. And Mai passionately loves the calm, quiet nature of the man from Hanoi.
Mr. Toan told Mai the truth about his marital status. Even though she knew he had a wife and children, she was willing to accept all conditions to live with him.
A silent wedding party without a representative from the groom's family took place in the countryside where the girl lived. The secret marriage went smoothly until Thanh discovered the truth.
In front of his children, Mr. Toan said he felt truly loved and respected when he was with his concubine. Through his father's comments about his concubine, Thanh believed that the two twins were his younger siblings, but he still wanted scientific evidence to confirm.
After a period of research, he learned that only a DNA test can accurately determine blood parentage. Before taking the twins for testing, Thanh went to hospitals to ask doctors for advice on DNA testing.
He was instructed by the expert to just take hair samples from the two children and his tests would accurately conclude whether the baby was the father's biological child. As a result, Thanh and the twins were not related by blood. Holding the conclusion in his hand, Thanh was stunned and speechless.
He was skeptical about the accuracy of the assessment process, so he went home and secretly took his father's hair and brought it to the testing center to make two samples. One sample is between Mr. Toan and his two twins, the other sample is his and his father's hair.
The examination results showed that Thanh and Mr. Toan were not related by blood, the two twins were his biological children. Holding the DNA test ballot in his hand, Thanh collapsed in the lobby of the DNA analysis and genetic technology center.
That evening, Thanh's family had an urgent meeting among family members. At this time, Ms. Lan confessed that she had kept her husband and children a secret for more than 30 years.
When they first got married, Mr. Toan often went on business trips, while Ms. Lan stayed at home and secretly had sex with her ex-lover. Thanh was her child with that man, not Mr. Toan's.
Tragedy continuously strikes, causing conflicts between members to reach a climax. Ultimately, they decided to divorce. Mr. Toan returned to live with his second wife, Mrs. Lan stayed in that house with Thao, and Thanh decided to rent a house of his own.
According to Ms. Nguyen Thi Nga, Director of Hanoi DNA Analysis Center, DNA paternity testing is the most accurate testing method today. If the DNA samples of the mother, child and father in question match each other in each gene, the accuracy of blood relationship reaches 99.999% or higher. That means that in fact the man tested here is the child's father.
If the two DNA samples of the child and the father in question do not match each other by two or more genes, then this man must be excluded 100% and the possibility of being the father of the child is 0%.
DNA testing using a set of 16 genes has high accuracy up to 99,999%. If you want a DNA test, you only need 10 strands of hair with roots, or fingernails or a blood sample.
