@jdcowle5 - Thank you for considering living donation! As for the kit, there should be instructions inside the kit. Take it to your local lab, they will draw the blood and should ship it back to Mayo Clinic for you. If there are further questions while you are there (or before you go) you can contact our living donor phone line at 866-227-1569. As for your return to work, every patient is a little bit different. If you have a sedentary desk job, you can likely return sooner than someone who has a physical labor job. The average is 3-6 weeks, depending upon your type of work, your recovery, and any issues you may have after surgery. Your nurse coordinator can give you a better estimate once they see you in evaluation. If you have any further questions, let us know. And thanks again for considering donation! - Kristin
