Can people's hospitals dispense with skin tests when injecting drugs?
Not all drugs need a skin test, but drugs that don't need a skin test are not necessarily allergic. Allergies are caused by a person's special constitution. Even if common and commonly used drugs are allergic, even if the skin test of drugs required to be tested is negative, there is no guarantee that allergies will not occur during use. So you go to see what medicine you are using, and whether there are any requirements for skin test in the instructions or even in the Pharmacopoeia. If you don't do it, you can talk to the hospital for theory. If you don't ask for it, you can't do anything. Use less drugs in the future, especially to explain your allergic history to your doctor.
