It's not that difficult to open a hospital in another world, right?

Since it is handled by modern medicine, it is natural to follow the ideas of modern medicine. Grete calmed down and looked at the child carefully again: what he had observed before was correct, the child's face was swollen, and there were wind masses on his face and hands, which was mainly due to allergies. He turned to the peasant woman who came in with her child and continued to ask:

"Didn't you eat any strange fruits? Didn't you pick any flowers? Where did the child go to play this afternoon?"

"How can you play! Little Remy is very sensible. Two years ago, he would have helped the family with work!"

Uh...disrespect. Grete wiped away cold sweat. How the original person spent his childhood was not yet fully connected in his memory, so he couldn't remember it for a while. But in my previous life, I was definitely still a primary school student when I was seven or eight years old!

Carrying a small schoolbag, I go to school every day, and I don’t even have time to think about how to blow up the school!

However, Grete still knew how naughty seven or eight-year-old children could be. When I was in the emergency department, parents rushed in every day with their children injured, sick, and for various reasons that were unbelievable. It simply challenged the limits of human imagination. Sometimes adults don’t think that their children’s peers may not know——

"Are there any children working with him? Can you call him and ask?"

Grete asked patiently. Before the peasant woman could answer, Uncle Edmund, the farmer holding the child next to him, had already answered:

"Yes, yes! There are two or three of them! - Why are you still standing there, go and call!"

Immediately some people ran away. Grete frowned and continued to think hard, trying to figure out what else might be the cause of the disease. On the side, the priest, who had finished looking at the child's throat, came over boredly:

"Why do you ask these questions?"

Gretel: "..."

Check for allergens!

Grete bit her tongue and almost stopped what she was saying. Allergy, this word was so common in the past life, even if you are not a doctor, you know what it is. But to say it in this strange world...

Grete is 100% sure that the curious baby priest in front of him will definitely get to the bottom of it. When asked, how to explain?

——Hypersensitivity, also known as allergic reaction, refers to an abnormal adaptive immune response that causes physiological dysfunction or tissue and cell damage when the body is stimulated by certain antigens?

It's very simple, very clear, just one sentence in the textbook...

It would really kill someone to explain!

Let alone another world, even if Grete had asked a non-medical professional to explain the word "allergy" in his previous life, if you put a complete set of 53 medical textbooks in front of him, he would be able to flip through the books for half an hour and then yell out. :

“Which book should I read if I’m allergic?”

That's right, for half an hour, I didn't even understand which book was about allergies...

Fortunately, Grete was the deputy director of the emergency department in his previous life, and he has rich experience in communicating with patients and family members. He tidied up his words and answered slowly:

"I ask these questions to see if the child has eaten, drank, or touched anything he can't stand."

"Poisoned?"

"It's not poisoning..."

Brother, who used the detoxification technique just now? Isn't it you?

After spending a long time talking and sweating all over, I finally explained the appearance of "allergy". The child's playmates during the day were also called. There were three of them, the oldest was less than ten years old, and the youngest looked to be only four or five years old. Gretel asked the question again in detail, and as expected he asked something different:

"It's salted fish! I saw Remi break off a piece of the salted fish hanging on the beam!"

"You're talking nonsense! We, Remy, are the most well-behaved and never steal food!"

The peasant woman jumped up like a female animal guarding her cubs, baring her teeth and claws and making a sharp voice. Mothers screamed, children ran, and men shouted to stop. The hall became a mess, and the volume reached 120 decibels again.

Gretel sweated. He shouted loudly amidst the noise in the hall:

"Stop arguing! - Someone go get that salted fish!"

No matter how much he suspects that salted fish is to blame, in the field of modern medicine, no doctor dares to make a diagnosis without conducting tests. Gretel has a salted fish in his left hand and a bowl of water in his right hand. Look left, look right——

"what fish is this?"

Forgive him that in his previous life he only knew how to eat, never buy or cook. The cooked dishes are placed in front of you. You can also identify what kind of fish it is. A raw fish is placed in front of you. This...

Can't do it, don't recognize it, say goodbye.

Fortunately, if he doesn't recognize it, someone will. The priest of the spring goddess stuck out his head, studied it with great interest for a moment, and finally came to a conclusion:

"It's cod.—Is that what you're causing trouble by eating?"

Just cod. Grete nodded secretly: People in such inland areas usually cannot eat sea fish. It is normal for them to be allergic if they occasionally eat it. He smiled and nodded to the priest:

"I guess the possibility is not small. However, we still need to verify it."

"How to verify? - Let the child eat again?"

"..."

Gretel Khan:

"The throat is swollen like this. If you let him eat, he has to be able to swallow it!"

"What should we do?"

No matter how you experiment, generations of doctors in previous generations have paved the way for those who come after you. The doctor didn't need to worry at all. He suspected it was an allergy and just sent him for a skin test.

It costs tens of dollars to do a test, put two needles in your arm and drop a drop of antigen, and the results will be available within half an hour. But now, now...

To do a skin test, you must first have an antigen!

Antigens that are sterile, have no obvious side effects, and whose protein content has been measured are displayed in large boxes in the laboratory. They seem to be readily available; but if there are no ready-made antigen products, they must be extracted from raw materials...

Gretel was a clinical major in his previous life, not pharmacy. But he also heard his pharmacy classmates cry that they had to extract the fish by hand when doing the project. They had to cut the fish into pieces, grind it with liquid nitrogen, add acetone to remove fat, stir, let it stand, and put it in a centrifuge...

After completing a set of procedures, it would take several days and nights, and I would be so busy that my hair and facial features were unkempt. It goes without saying how many drugs and instruments are needed in this process.

In previous lives, various seemingly ordinary conditions were supported by the country's strong industrial strength. In this alien world, the only thing Gretel can be sure of is:

What he can currently do is only the first step in preparing the antigen.

——Cut the fish into small pieces and soak it in water...

Gone.

Then, jump directly to the last step of the skin test.

"Bring two needles here! And a bowl of water!"

On the child's left forearm and right forearm, put a drop each of clean water and water mixed with fish meat, then use two needles to pass through the droplets and prick the skin gently each time to pierce the skin without bleeding. Gretel pinched his wrist, silently counted 60 times, wiped the droplets of fluid on the child's arms, and then——

"What to do now?"

"wait."

For the prick test in the skin test, the results of Type I allergies—that is, seafood allergy, nut allergy, and paint allergy—are observed 20 to 30 minutes after antigen stimulation. The child is temporarily out of danger, and the next step of treatment has to wait for the test results. What can be done now...

Just wait.

Look left, look right, sit there, doing nothing.

Gretel: "..."

No, I have to wait for half an hour. Is there no one to send me to eat? !
