You're also supposed to save the tick to make diagnosis of tick-borne illness easier. Years ago I had what felt like a four-day hangover after getting bit so I went to the doctor; he gave me Doxy and sent my blood off to the lab which later confirmed that I had Rocky Mountain spotted fever. Supposedly it's easier/more conclusive to test the tick itself for pathogens than your blood.
