The easy test is to get out on the freeway and accelerate up to the
speed limit (will maybe a little over) in a bit of a hurry. If it is
blocked, you should feel a lack of power and slow acieration. It may
hit like a brick wall. This is not a sure test, but it works well
most of the time.

If you don't know, likely it is not overly clogged.

Why do you think it is clogged?
