A blood check or saliva oral exam for checking testosterone level?

I wanted to check my testosterone levels next time I turn to the doctors, but which test is best? Blood test or saliva test? I want something that's pretty accurate.
Answers:    Blood test are the ONLY accurate tests.

Even so, understand that testosterone is given in a RANGE base on AGE and sex (yes even females generate SOME testosterone). An exact number is not important, What is important is where that number lies surrounded by the "range chart".
BLOOD
