I took several surveys conducted by persons in the psychiatric healthcare field. Ultimately, it was a team of psychiatrists that made the diagnosis.

I definitely am not a proponent of self-diagnosis tools. In my opinion they are at best tools that may be indicators of mental health issues but should never be used by a layperson for diagnosis purposes. Rather, you are best to seek the help of a professional.

To my knowledge there is not a physical test (ie. blood work) that will diagnose a mental illness.

Mind you, Switzerland has always been at the height of knowledge and practices within mental healthcare services. There may be practices there 'light years' ahead of what is routine in the rest of the western world. Would I be correct to assume too that access to these services is more readily available?
