Although Huang Shi said it very carefully, in fact, he is half a bucket of water, he knows it but does not know why, he does not understand that blood type is mainly classified according to the blood group antigen contained in human blood, and at the same time, in addition to the blood group antigen mentioned above, there is also a corresponding substance, called blood group antibody.

Blood type A has anti-B antibodies, and blood type B has anti-A antibodies, and when these opposing antigens and antibodies meet, they will undergo the agglutination reaction referred to by biology, which is clinically a phenomenon that dissolves and destroys a large amount of human blood.

However, Huang Shi Zhilu said that his blood type is type O, because this blood type can be exported to people of any blood type, so he is called a universal blood transfusion and a special blood transfusion. On the other hand, AB is a blood transfusion that can accept any blood type, so it is called a universal blood recipient.

However, he also heard Chen Lishui say that in fact, the transportation between different blood types can generally only be transported in small amounts, not large quantities. If you want to have a large blood transfusion, it is best to do it between the same blood type. So at the beginning, Huang Shi thought that if there was no way to test the blood type, he could only act as a mobile blood bank by himself, the chief.

Now that he has the serum reagent, he can let someone else be used as a blood bank, but Huang Shi estimates that he must also be prepared to be drawn blood, although his blood may not be of use, because he also has to set an example for these natives under his command.

"Hong'er, you take out a piece of glass from inside." Huang Shi is ready to instruct Hong'er on how to test her blood type.

Hong'er carefully took out a narrow piece of glass from the box, because the edge of the glass piece was not polished at all, according to the chief, this is easy to cut the gloves or simply cut the hand, so you must be careful when taking it.

A white towel had now been laid out on the table, and the piece of glass was now lying flat on it, and Hong'er was waiting for Huangshi to guide the next step.

"Wait a minute, you're going to use this red straw to suck type A serum, and this blue straw to suck type B serum, don't get confused, do you know it?"

Hong'er nodded, "Zhilu said, chief." ”

"Well, that's good, you can drop a drop of reagent on each end of this now, slower, just one drop."

"Good, chief." Hong'er slowly pinched the red test tube, dropped a drop of reagent on the glass piece, then inserted the red straw into the shelf, took a blue straw, and used it to suck less than half a tube of reagent from another large bottle with the letter B written on it.

Huang Shi saw that Hong'er was dripping no more or less, all one drop, so he nodded and said, "Now you can take a new straw and drip Ah Wei's blood on them." ”

Hong'er took the small bottle on the table, it was taken out of her arms earlier, and it contained Ah Wei's blood, which was specially left by the chief before sending Ah Wei into the upper realm.

Carefully holding a straw to draw blood from the vials, and then Hong'er dropped a drop of serum on both ends of the glass as Huang Shi said, looking at the two drops of dark red blood on the glass piece, she wondered if the blood would turn white or green after a while.

Huangshi didn't know what to do, he just heard Chen Lishui say that this blood type test is to see if there is a hemolytic reaction, as for what the hemolytic reaction looks like, Chen Lishui has not described it to him, so he can only rely on himself to witness and verify it later.

The two little guys next to him were also a little curious, and threw their heads over, "Chief, why hasn't there been any movement yet?" ”

"Wait, they're not that fast." Huang Shi was also a little confused by what they said, and now he was worried about one thing, that is, if the blood was released for a long time or heat, would it deteriorate. If the serum on both sides reacts or does not react, is it really type O or AB?

Just as the four of them poked their heads into staring at this piece of glass, the people who had gone to move the tables came back one after another, "Chief, where are we going to put these tables?" ”

"Put one on my side, and the others on whichever side, and you can line them up again."

……

Looking at his watch, it had been several minutes, and Huang Shi was a little anxious, wondering if he had let his crow's mouth be right, it would be bad. But fortunately, after a while, the sharp-eyed plum exclaimed, "Look, look, here and here, it's changed." ”

"Changed, where?"

"You see there's something on their right."

The other people took a closer look, and sure enough, the blood on the right side seemed to slowly begin to coagulate some small particles. The blood on the left side has not changed at all. This discovery finally made Huang Shi breathe a sigh of relief, and he secretly expressed his gratitude to the Buddha and Marx in heaven.

"I'm testing you, and you say, what kind of blood type is this?" Huangshi, who came down easily, jokingly wanted to test the three of them, because it was the three of them who waited for the specific operation.

"I'm going to think about it......" Umeko bit her finger and was about to recall what the chief had said earlier.

Ah Jing had already spoken, "Chief, I think it should be Type A." ”

Huang Shi let out a "wow" in his heart, and now his understanding of the logic and memory ability of geniuses has been upgraded to a higher level, and then he saw that the other two people were still frowning and thinking, people's answers have already come out, and people are really incomparable.

"Okay, then tell me, what is Type A?"

Seeing that the chief did not deny his answer, Ah Jing knew that he was right, so he replied with a smile, "Chief, after I heard you say it just now, I thought so. Left and right are not condensed, it is O-type; The right is condensed and the left is not condensed, which is type A; The right is not condensed and the left is B-type; It is condensed on the left and right sides and is an AB type. ”

"Ah, that's a very good point." Huang Shi didn't expect Ah Jing, he was able to summarize a set of slips by himself in a short period of time, which is much stronger than the XX, XY and other sayings that he copied from Chen Lishui, and his two adults are not as good as a child, which is really embarrassing.

……

Ah Jing wrote his brother's name on the notepad in a dignified manner, and wrote a big "A" in the middle of the page, and then handed it to Huang Shi to read, "Chief, do you think this will work?" ”

Looking at the dignified and beautiful little guy written down on the paper, Huang Shi in addition to the secret appreciation, but also a little ashamed of his dog crawling words, was about to praise him, suddenly remembered to write like this, it seems that it is easy to make mistakes, or more detailed and specific, and can be rechecked.

So he took the pen from the hand of the Ajing, and after drawing a few lines in the notebook, he said to him, "Add the gender and age of a man and a woman to them here, and then you write serotype A here, no response below, serum type B here, blood coagulation reaction below, and then write the Gregorian date here." ”

"Yes, chief, that's a good idea." Ah Jing glanced at it, thought about it, and understood Huangshi's intentions, and he quickly wrote it on the paper.

That is natural, Huang Shi is also a little complacent in his heart, thinking that he was in Xitong Company, he can slowly climb from a programmer to the position of vice president, in addition to his own hard work, continuous innovation of management methods has also helped him a lot, such management details are not everyone can imagine.

"Chief, what am I going to do?" Meizi saw that Ah Jing had something to do, but she was left aside, and hurriedly pulled the chief's sleeve, she found out today that the chief was not as majestic and terrible as she imagined, but very much like an amiable uncle, and couldn't help but get a lot closer.

"You, you have something very important." Huang Shi looked at the little girl, a little funny, because she seemed to be very sticky. The little girl's eyes are big, and her fleshy little face is a little dark, but she is still a very cute little girl.

"What is it, chief?"

Seeing that the little girl was a little anxious, Huang Shi didn't tease her anymore, "What about you, you have three jobs, one, you have to use this cotton swab dipped in alcohol to disinfect the fingers of each of them for blood testing, do you understand?" ”

"Well, chief, I understand." Meizi nodded, she had helped Ah Jing eliminate the poison just now, it was not difficult at all.

"And second, you're going to use this." Huang Shi took out another cardboard box from the storage box next to the table and put it on the table, "You want to use this lancet to prick their sterilized fingers, puncture them, and then squeeze the blood onto the glass piece, do you understand?" ”

Meizi thought for a moment and asked Huang Shi, "Chief, is it like Ah Wei's blood just now, is it going to drip on both sides?" ”

"yes, but don't prick someone's finger too much, just prick it gently." Huang Shi was afraid that Meizi would have no experience, so he made a special explanation.

"Okay, chief, I wouldn't do that, so what's the third one?"

"Thirdly, you have to take a clean cotton swab and let them press it to stop the bleeding, and then let them go to the back to rest."

Meizi nodded, indicating that she understood everything, it seemed that her work was very important, and there were three more jobs, and she was now looking forward to when she would start.

Huang Shi saw that the two little guys were eager to try, only Hong'er was a little nervous, if it was when the two of them were alone, he would definitely pinch her slender hand, or pat her small waist to express his encouragement to her, but it was not suitable now, so he could only smile at her and say, "Hong'er, don't be nervous, look at the two of them, they can't wait." ”

Hearing this, all three laughed.

Huang Shi saw that Hong'er's nervousness had eased a lot, so he continued, "Okay, just like we said earlier, now let's start the first blood test." ”

"Okay, chief, let me be the first to come." Ah Jing put the notebook in his hand on the table, stretched out his left hand, and then handed it to Meizi.
