Can I trust my ASD diagnosis?

So last year I got diagnosed by my psychiatrist. I live in the US if that matters. He did not give me the ADOS or any testing. He just asked me questions based off of the DSM-5 and about my life, social problems etc. After about a 15 minute talk I was given a diagnosis of autism. However online it says if there was no ADOS testing, or other tools it may not be accurate. Now I’m questioning myself. Do you think I should get retested?
