Some companies make test strips for that purpose (BG comes to mind) but you'll probably have a buy more than you need. A reasonable analysis is to smell them and look at the color. If any are dark and/or smell burned replace them.
For about $20 + shipping each you can send them to Blackstone in Indiana for chemical analysis. I'm not sure about brake and steering fluids, but I sent my ATF to them, and also send motor oil every so often.
