Chapter 1028 (1/2)

Generally, there are two kinds of allergens, one is in vivo test and the other is in vitro test.

In vivo tests include split skin test, prick test and patch test. Intradermal test and prick test are mainly to prick allergens into the patient's skin to observe whether there is allergic reaction.

For example, penicillin skin test is this method, but this method needs to know what allergy it is, or take several allergens to test one by one to verify which allergy it is, but this girl has been allergic. Now it's not suitable.

The patch test is mainly used for cosmetics or metals. For example, there was a person who was allergic to copper before. As long as you rub the copper product on the patient, you can see immediately. The cosmetics are applied behind the ear or inside the upper arm. Whether there is allergy depends on whether there is redness and swelling.

But it doesn't apply now.

Therefore, only in vitro testing, mainly blood sampling, IgE antibody detection and IgG antibody detection (food intolerance detection), as long as a drop of blood, the accuracy is still high.

The nurse came to draw blood and immediately took it to the laboratory for testing.

At this time, the girl woke up, opened her eyes, and suddenly screamed, stretched out her hands and fumbled, ”where am I? What's the matter with me? ”

”What's the matter? What's the matter? ” The students hurried around.

”I can't see!” The girl burst into tears, groping with her hands blankly, and tears rolled down.

”What?” The students were surprised and looked at the girl. Why couldn't she see with her eyes open?

”Don't be afraid, I'm a doctor. Let me see!” Guo Xiang quickly took out his small flashlight and shone it in the girl's eyes. There was a response, but there was no focal length.

Guo Xiang stretched out his finger and shook it in front of the girl. ”Can you see?”

”I can't see. I can't see anything. It's dark in front of me. What's the matter with me?” The girl cried and panicked with a pair of blank eyes. Other students were shocked. Won't she be blind? How did this happen?

”Don't be afraid, don't be afraid!” Guo Xiang grabbed the girl's hand and comforted her, ”this is temporary. It should be temporary blindness caused by allergy. As long as the allergy is solved.”

”Are you a doctor?” The girl quickly clenched the doctor's hand with tears on her face, ”am I really not blind? Are you blind? Doctor, please help me! ”

”Don't be afraid. You're not blind. Your eyes still respond to light. We are looking for the cause. If we find the cause, the treatment will be good. Are you allergic to anything? ” Asked Guo Xiang.

”I don't think so...” the girl wiped the tears from the corners of her eyes and choked, as if she remembered something.

”But I've been looking for measles for years. My parents also took me to the hospital. I saw both traditional Chinese medicine and Western medicine, and took countless medicines, but it didn't work at all. I still often had a rash. Is this also because of allergies? ”

Guo Xiang nodded, ”very likely. Your classmate said you ate fried noodles just now? Did you eat noodles before? ”

”Yes, but I eat very little. I'm from the south. I usually eat rice and noodles several times, but I'm all right.” The girl said.

”After eating fried noodles with sauce, how long will the sports meeting be held?” Guo Xiang asked the students nearby.

”It didn't take long to start after dinner?”

”But Lin Nan's project seems to be two hours later?”

”She began to warm up for a while before it was her turn. She fainted after running for a while.”

The students began to talk.
