There's this site where you can order blood analysis tests without having to see a doctor:

There's a participating lab very close to me, very convenient.

I could order the test online, and go get blood drawn nearby, and have the results sent to me.

They have a December special for sixty bucks to get ten basic analysis done.

I haven't been to a doctor in 22 years, should I do it?

I can't really afford the sixty bucks but I wonder if it's a good idea to spring for it anyway.
