Good doctors test their patients for drug use if they suspect you're abusing. Most legal medicine will have bad interactions with illegal drugs and they could kill you if they don't take that into account.
Doctors do not typically test for drugs unless there is a specific medical reason to do so, such as if drug use is affecting your health or treatment. If drugs are found during a test, the doctor may discuss this with you as part of their overall assessment and treatment plan. However, your confidentiality and privacy will be respected.

All opiate drugs...
They do.
The FAA actually usually does not screen or test for drugs at all. Instead, they tend to screen for diabetes and kidney disease.
They can test you for any and all drugs that could possibly be in your system, prescription or otherwise.
It all depends on what they are looking for because most doctors will only test for what they think is wrong. For example if you have taken drugs the day before and are having a test to see if your anaemic then they wouldn't know about the drugs. A blood test can show HIV,Aids,Pregnancy, high cholesterol, high blood pressure, low blood pressure, hepatitis, anaemia and alot of other things too =)
all of them, just stop using drugs and you won't get into trouble
