What kind of work up is required for iui? also what kind of testing is to be done if iui+meds didn't work?

Details: Depends on how many details you really want! You would have likely gone through hormonal testing and pelvic ultrasound and possibly even be taking meds to stimulate ovulation. Your partner would likely have had sperm testing and depending on the situation hormonal labs and ultrasound himself as well although less likely. If the IUI doesn't work the recommendation would likely be to try IVF.
