Did you have a lot of tests, and what were they like?

I had a pin test where they injected (under my skin) tiny amounts of the stuff that can cause allergies. I had that test because allergies can cause the symptoms of asthma or make asthma worse. They also put a "sleeve" on my finger to measure the amount of oxygen in my blood. And I had to blow as hard and as long as I could into a peak flow meter so they could figure out how well my lungs work.
