Song Tingshen nodded, eighty percent is fine, at least it will be closer, if you are lucky, the other pair does not match at all, and the closer pair is.

"I have a case here, the child has liver cancer and wants to have a liver transplant, but his parents are not his biological parents, and now I have found a suspected one, can you help me do a paternity test for them?" Song Tingshen said.

"Yes, but as I said earlier, the success rate is not 100 percent......," Zhang Ming said.

"It's okay, just use the elimination method." Song Tingshen said.

"That's okay, you can let them come over, or just draw blood and send it over." Zhang Ming said.

"Okay, I'll have my student send it to you." Song Tingshen hung up the phone and said to An Zehan: "You take these two couples to have their blood tested, and then take a tube of the blood of the two who are AB type and Chen Yuan, pack them in a crisper box, and send them to this address......

Song Tingshen tore up a prescription and wrote down Zhang Ming's address, "Give the blood sample to a teacher named Zhang Ming." ”

"Okay." An Zehan nodded and took the two couples to a blood test.

"Doctor, after this examination, do you know who Yuanyuan's biological parents are?" Chen Yuan's mother asked in surprise.

Song Tingshen nodded, "If nothing happens, you should know." ”

It is unlikely that both of them are genetically similar to Chen Yuan, and even if they do not match 100%, they can still be identified.

"When will we find out?" Chen Yuan asked urgently, he couldn't wait any longer.

"It may take a week, and I'll urge it again later, to see if I can expedite it, and if it is expedited, it should be done in two or three days." Song Tingshen said.

"Two or three days?" Chen Yuan's mother was a little disappointed, thinking that the results would be available immediately.

"It's already fast, and it's not in a hurry." Song Tingshen said, "Either you find a place to live first, and then come back in two days to get the results, if there is a match, you also have to check your body to see if you can do it." ”

"By the way, if there are Chen Yuan's parents among them, are they willing to donate their livers to Chen Yuan?" Song Tingshen asked, after all, they haven't lived together for so many years, if they want to say that the relationship is definitely not deep enough, it depends on whether they value family affection or not, after all, Chen Yuan is a dying person, and it will not affect them if he is not there.

"We talked about Yuanyuan, and they were very sympathetic, after all, Yuanyuan could also be their child, and they would not die without help." Chen Yuan's father said.

"That's good." Song Tingshen nodded, "Then wait for the result." ”

After a while, the two couples came back and said that they had determined that Aunt Wang and Uncle Lin had AB blood type, and An Zehan drew blood for them.

An Zehan followed from behind, "Chen Yuan, you can come too, your blood hasn't been drawn yet." "I forgot about it just now.

"Oh!" Chen Yuan answered and went over with An Zehan.

After the blood was drawn, a few people went out to find a small hotel to live in, and naturally Chen Yuan's family was responsible for the expenses.

Invite them to come to the capital, if they can help them find their biological son, they will be happy, even if it is not the pair of Chen Yuan's parents, they will be regarded as traveling to the capital, so when they heard Chen Yuan say that he wanted to bring them to the capital, they all agreed very happily.

Two days later, Zhang Ming came to the conclusion that Aunt Wang and Uncle Wang should be Chen Yuan's parents, because the other pair of leukocyte antigens are too different, this is the elimination method, and Wang's pair is Chen Yuan's biological parents.

"You're my real parents?" Chen Yuan was very excited and finally found it.

Aunt Wang and Uncle Wang were also very excited and a little sad to hear that Chen Yuan was their biological son, the son they had raised for decades was not biological, this person who had cancer was still biological, how could people not be sad.

"Child, we ......" the two also burst into tears, "You are our son?" ”

"Then your child is our son?" Chen Yuan's parents were surprised and delighted.

What is surprising is that Chen Yuan is still not his biological child after all, but he is happy that his biological son has found it, and he is still a healthy person, and Chen Yuan also has hope that he can be cured.

Uncle Lin and Aunt Lin were also very happy for them, "Congratulations! ”

Aunt Wang and Uncle Wang hugged Chen Yuan and cried bitterly, "Child, you have suffered!" ”

After some acknowledgment, the two sides slowly calmed down.

"In this way, I want Aunt Wang to donate her liver to Chen Yuan, are you willing?" Song Tingshen asked.

"Yes, yes, of course I am willing to save my son." Both couples nodded.

Song Tingshen nodded, "Then do a series of examinations to see if your body is suitable." ”

He took out a questionnaire and asked for his name, age, etc., and then asked if he had any previous medical history.

"Have you had any previous diseases, or have you had high blood pressure, heart disease, etc.?" Guo Xiang explained.

"I don't have high blood pressure or heart disease, but I did have liver cancer." Aunt Wang said.

"What?" Everyone was shocked, "You also have liver cancer?" ”

"yes, but that was last year, but fortunately, I found it early, had an excision, and now it's all fine." Aunt Wang said.

Song Tingshen looked at Aunt Wang and put down the pen in his hand, "That's not good, it can't be done." ”

"Then why didn't you say it earlier?" Chen Yuan's mother's voice suddenly raised.

"You didn't ask, but besides, wouldn't it be good for me? I'm doing well now. Aunt Wang said.

Everyone was speechless, and it was impossible to ask a person who had had liver cancer to donate his liver to others.

"That'...... Is there no hope again? Chen Yuan's spirit suddenly declined, the whole person withered like a cramp, looking for so long, traveling so far, but coming to such a result, how can it not make people sad?

"I, this ......, can't give my liver to the child? Isn't that kid hopeless? "Aunt Wang and her husband are also in pain, is the son who has just been recognized going to die?

"Why not?" Uncle Lin question.

"Aunt Wang has had liver cancer, the liver has been damaged, although the tumor has been removed, the stool liver is not a healthy liver, she is fine now, but the liver function is working. In addition, although the tumor is removed, there is no 100% guarantee that there are no cancer cells in the liver, and in fact, liver cancer is easy to recur. ”

"And with a liver like hers and half of it, let alone herself, even if it is given to Chen Yuan, I am afraid it may not be successful, what we need is a healthy liver." Song Tingshen said.

"yes!" Guo Xiang nodded, "A healthy liver can't be 100% guaranteed to succeed, let alone a damaged liver, I'm afraid the two of them won't be able to save it at that time." ”

"What then?" Chen Yuan's mother exclaimed.

Everyone was silent, and there was nothing they could do.

Chen Yuan smiled bitterly, why did God torture himself like this?

Obviously gave hope and shattered it fiercely.

"This ...... Was it inherited from Aunt Wang to Chen Yuan? Aunt Lin couldn't help asking.

"Not really." Guo Xiang shook his head, "Liver cancer itself is not hereditary, but liver cancer is clustered in families, mainly related to hepatitis. It may be that Aunt Wang is a carrier of hepatitis B, and Chen Yuan who gave birth to her is also a carrier of hepatitis B. Now newborns are not vaccinated against hepatitis B......"

In later generations, almost every newborn will receive the first dose of hepatitis B vaccine within 24 hours of birth, just to block the virus carried from the mother.
