Chapter 682 (2/2)
In July, the results of the postgraduate entrance examination came out, and sure enough, they were admitted. Then they went to the school for a second examination. After the interview, they basically nailed it on the board.
Lu Xiaobei didn't tell Cheng Juan and Lu Yuanping about all this. He just got the notice and left.
Cancer hospital, Guo Xiang, they mentioned Chen Yuan who came to see a doctor two months ago, ”it's been two months. They haven't come yet. Haven't they found his biological parents yet? I'm afraid it's too late if they don't come again.”
”It's hard. It's not easy to find someone now. It's ok if they are all in the same county. Where can we find outsiders?” Guo Xiang shook his head.
While he was talking, several people poured in. Guo Xiang was surprised to see that it was Chen Yuan and them. ”Are you back?”
”Have you found your biological parents?” Anzehan also asked hurriedly.
”If you find it, you don't know which one it is.” Chen Yuan nodded with a trace of joy on his unhealthy face.
”What do you mean?” Song tingshen asked, did you find it or not?
There are two couples standing behind Chen Yuan's parents. It seems that they are very simple in dress. They should not be from a big place.
”We searched for a long time and asked a lot of people. At that time, four people gave birth to their sons in a delivery room.” Chen Yuan's mother said, ”we asked the hospital. Except for one blood type that is obviously wrong, the two couples are very consistent with Yuanyuan's blood type.”
”What a coincidence?” Guo Xiang was surprised.
”Yes, after knowing the blood type, we immediately tested the blood when we found someone, and specially asked the doctor about the inheritance of blood type. I have type AB blood, so my parents may be type A and type B, one type A or type B, and the other is ab.”
”Just like Uncle Wang, he is type a blood, Aunt Wang is type AB, uncle Lin is type AB blood, and aunt Lin is type A.” Chen Yuan said.
”What is your son's blood type?” Asked Guo Xiang.
”It's all type A.” One of them said, ”we didn't know what the blood type was before, or did we know it after Yuanyuan found the child. But our children are type A, isn't that our own children? ”
”This is not necessarily. You may also have a child with type AB blood. Chen Yuan may still be your child.” Guo Xiang said.
”But in this way, how to judge who is Chen Yuan's biological parent?” Asked anzehan.
”This...” Guo Xiang paused for a moment. Yes, it seems that there is no DNA test at this time. It seems that it only existed in the 1990s. What can we do?
Although any one of them with type AB blood can donate liver to Chen Yuan, the one who is not has no obligation. After all, the operation is still risky.
Moreover, when the project was approved, it was stipulated that only parent liver, that is, the liver of immediate relatives, could be used, so others were willing but could not be used without parent relationship.
Guo Xiang asked song tingshen, ”teacher song, can't you do paternity testing now?”
Song Ting thought deeply, ”wait, I'll call and ask.”
Song tingshen called a classmate who was engaged in genetic research.
When the phone was connected, a man's voice came out, ”Hello, who?”
”I'm song tingshen.” Song tingshen spoke.
The other party seemed surprised, ”tingshen, long time no see, how did you think of calling me today.”
”Zhang Ming, I want to ask you something.” Song tingshen said, ”with current technology, how can we identify whether a father and son or mother and son are biological?”
”DNA technology has been identified abroad, but our country has not yet. At this stage, it is mainly through the anti original of white blood cells for paternity identification, but the success rate is not high, up to 80 percent.” Zhang Ming said.
