How likely is it ADOS will DX and be wrong?

[hereidrawtheline]

DS is being referred for the ADOS test and I am getting cold feet. Basically I wont beat around the bush I am afraid he is just precocious and the negative stuff is too much my fault. I dont want him being mislabelled as ASD. If the ADOS test says he is on the spectrum what are the odds they are wrong?

Thank you. I am getting myself quite upset thinking about it all atm. I know it is a positive thing really but don't feel ready to face up to it...don't feel I ever will.
