I understand wanting to know one's IQ and to have a good result... there's a tacit value attached to it in pop culture, and much is made of people who are thought of as 'intelligent' at work.
I don't think the IQ score as a raw indicator of potential is wholly pointless as much as it is severely limited in scope. As Pondering above pointed out, there are different forms of intelligence. It's been often enough that I've met people who - and I appreciate I'm assuming and may be wrong - didn't seem conventionally gifted as in 'high IQ', but who were definitely smart and talented, just not in a rocket scientist-way. But the proverbial rocket scientist might not be a great (or even mediocre) actor, or profoundly and implicitly understand people's motivations, group dynamics, presentation, communication...
It's a simplistic example. But, I find that often enough, people who I suspect - and I again I may be way off! - might not be particularly intelligent in the conventional way that IQ tests measure, would be very misclassified (terrible word) as average or not gifted or just plain 'not (very) intelligent'.
For what it's worth, I got presentable results in the IQ tests I was given, but the fact that those scores are documented in a folder somewhere has never done anything for me. (Nor was it intended to, I suspect.)
It seems like nothing to worry about unless it's used against you. Otherwise, your IQ test score is fundamentally unimportant, generally. If you're seeking entrance to a job / career path / field of study that administers some sort of IQ test upfront - I believe you can train for them, contrary to what is generally said. And I think it was mentioned upthread: if you're not motivated, not focused or not feeling well, it will affect your result.
As far as figuring out your actual intelligence - tough one. I'm not aware that it's currently possible, and I'm not sure what a truly comprehensive IQ score, if it were to exist, would come to mean. I think it might come to be too easily equated with a person's worth.
I'm sure you have talents, interests and abilities - those are the things that matter. As far as IQ scores go, the most benign consequence seems to be that they don't matter. I can think of more ways that they could be used to hurt a person than to help them.
