I'm already certain that I have Asperger's. At 17 years old i don't think there's much use in getting an official diagnosis.
A diagnosis is useful if there are services that are available to people who are diagnosed, such as therapy or educational assistance. It is useful if you feel that your Asperger's may affect employment, because the Americans with Disabilities Act only applies to people with a formal assessment. There may be value in having a diagnosis for social welfare if you foresee a situation of being unemployed etc, and a longer history of diagnosis may help.
Even if you never plan on using the diagnosis, it is better to have it before a problem rather than seeking a diagnosis to deal with a problem, e.g. if you are ever arrested and officers think your speech or actions are suspicious.
Someone said you can not serve in the US military with a diagnosis of Asperger's syndrome, and the people variously claim that health insurance is and is not affected (it isn't where I live, by law), so you need to check these for your own situation and location.
