Everyone was stunned by Jiang Huaixu's behavior. Fang Zhan, the head of the Fang family, heard this and hurried forward to ask.
Jiang Huaixu said, "Now Doctor Qiao can only keep your son alive by giving him medicine. His success depends entirely on whether he can survive today and tomorrow. I have another method to help him recover his energy and blood, but it may be difficult for you to accept, just like the cesarean section. I would like to ask Mr. Fang and Mrs. Fang for your decision."
"Tell us first, and then the master and I will consider whether to use it or not after we hear it." Wan said.
"This method isn't particularly unusual. Since the patient has lost excessive blood, we need to replenish their blood. There are only a few common types of blood in the human body. By transfusing blood from someone with the same blood type as the patient, we can achieve the goal of replenishing their blood."
As soon as Jiang Huaixu said this, it caused a commotion in the crowd.
One student couldn't help but ask, "How do you know there are only a few blood types in the world? Don't they all look the same? I'm afraid you got this from some sorcery?"
"I've never heard of such a thing. If blood transfusions are really possible, the blood of a close relative should be used. How can we use blood that is not from the same bloodline?"
······
After listening to the students' discussion, Fang Zhan was also very confused. "If Doctor Jiang needs blood, he can use mine and Aunt Xia's, but..."
He paused and continued, "Has your method ever worked? If the blood of two people can truly blend, why have I never heard of such a thing?"
Jiang Huaixu explained simply, "Because a blood test is required before a blood transfusion. I just said that only blood of the same type can be mixed. If you randomly transfuse blood and make the wrong choice, it can be fatal. The method I know is the blood test method, which is the only way to do this. As for whether this method has been used, I won't lie to you, I haven't used it, but I have seen others use it successfully."
Fang Zhan and Wan looked at each other, not knowing what to choose for a moment.
Wan asked again, "How much blood is needed?"
"As long as there are enough people with the same blood type, a little blood from each person will be enough. You don't need a lot."
As soon as Mrs. Wan started speaking, Jiang Huaixu suddenly remembered something. She cast a subtle look at Fang Zhan. She quickly added, "I think I've made it very clear. A small amount of blood loss from an injury is not harmful to the body. I only need to make a pinhole-sized incision to draw the blood out. You don't have to worry about losing too much blood. If you are willing, please step forward first."
After she finished speaking, she ignored what the county school students said and said to Fang Zhan, "Master Fang, please ask the servants to clear out another room so I can draw blood."
Fang Zhan thought for a moment, then gestured to the servant, who then left. He then said to Jiang Huaixu, "Take mine first. Blood relatives should always have the same blood type."
"I, I can also draw blood. As long as it can save my son, just do it!" Aunt Xia's emotions were not very stable. Her eyes on her fair face were slightly red and swollen, which made her look more fragile.
It's hard to tell from her appearance that she is a mother of three children.
Fang Zhan's face showed a look of heartache. "Your foundation is not good to begin with. Losing blood will be harmful to your body. I'm here, so you can relax."
"Don't worry, I still need to make some preparations before this."
After comforting the two, Jiang Huaixu said to Wan, "Madam Fang, I need something. After thinking it over, I think it's most appropriate to talk to you. How about we talk for a moment?"
Wan nodded and followed Jiang Huaixu away. Behind them, Aunt Xia covered her face with her hands and shed tears, while Fang Zhan was still whispering consolation to her.
"Mrs. Fang, I called you here to talk to you about blood type." Jiang Huaixu said in a low voice.
Wan looked confused and puzzled. "Although I don't quite understand what you're saying, I'm willing to have my blood tested if you need me to."
"No, that's not what I'm talking about," Jiang Huaixu said. "A parent's blood type can determine a child's blood type. In other words, the parent's blood type can be used to infer a child's likely blood type. If a child's blood type isn't within the inferred range, it means one or both of the child's parents are someone else."
After making his words as easy to understand as possible, Jiang Huaixu glanced at Wan's still calm expression and continued, "Of course, this method also has coincidences. It's common for a child's mother to be known, but the father isn't. If the adoptive father and biological father have the same blood type, then it's impossible to determine. Ultimately, this kind of thing depends on luck."
Wan was silent for a while, then she said with a bitter smile: "It seems that you have made up your mind."
Jiang Huaixu shook his head. "I'm not sure. I wouldn't be sure until I feel Master Fang's pulse. But it just so happens that something like this happened, and I know you're hesitant, so I'm thinking about whether to give you a push. Of course, whether to do it or not is entirely up to you. It's just a gamble."
"No wonder my cousin said you don't act like a child. You have such insight and foresight at such a young age. It's truly admirable." Wan took a deep breath and said, "Since you want to gamble, then let's do it. If you lose, I'll never mention this again. If you win, I won't allow anyone else to taint the Fang family's bloodline!"
A smile spread across Jiang Huaixu's face. "Then I'll go get ready."
Since she accidentally exposed this matter, she should put an end to it. The most important thing is that according to the information she has collected in recent days, Mrs. Fang is a good person, and good people should be rewarded. It's as simple as that.
Jiang Huaixu walked into the room prepared by the servants and called Jiang Erlang in. Blood tests require serum, which is available in this medical space.
The blood test was simple. She simply explained to Jiang Erlang how to do it and left the job to him.
Afterwards, she asked Fu Tuan to help her find some inconspicuous blood-drawing devices in the system mall, such as thin rubber tubes, small porcelain jars, etc. She connected the needle to the thin rubber tube that had been rolled in boiling water and tied it tightly, and then connected it to the porcelain jar to make a simple blood-drawing device.
