which State are you in?

If you want to be a mid or nurse later, working in path will be great experience for you. Venepuncture (blood taking) is suppose to be a standard in all nursing courses although most students find they don't get to practice it on clinical's and usually find their first practical experience is when they are working on the wards. Most hospitals make you do an independent hospital based course to be able to cannulate someone (it isn't usually taught as part of a Uni course). You won't be cannulating anyone working in a pathology centre but you will become an expert in getting blood out of people!

You don't need nursing quals to be a pathology collector. You do a course through TAFE. You'll also want a senior first aid qual.

Good luck with it!
