Skin test is why can needles be used repeatedly

In layman's terms, skin testing is to test your ** with a trace amount of medicine to see if there is an allergic reaction.

The needle can only be used once.

It cannot be used repeatedly, the skin test is only a test for allergic reactions.

For example, penicillin, a skin test is to see if you're allergic to penicillin, because penicillin allergies can kill people.

For example, penicillin, the skin test is to see if you are allergic to penicillin, because penicillin allergy can kill people, and it cannot be used repeatedly, because on the one hand, it will be contaminated by environmental pathogens, and on the other hand, everyone will have a different disease, and if the first person has an infectious disease, the next person will be very dangerous.
