HELLO! I don't know much about medical tests and what human-grade things can be used for ferrets....but.....there's a centrifuge and other medically-related items available on a special website that is really helpful. It's called SHOPGOODWILL.com and it's kind of like eBay. It's an auction site for Goodwill stores across the US. You can bid on everything from new/used jewelry to clothing to antiques to cars. They occasionally have medical stuff that may be useable for ferrets - but, even if not for ferts, you might find something cool for yourself. Check it out when you get a chance..... oxox.....ferretmama [Posted in FML 8044]
