Yup I have to self cath, and the injury had happend at home. Its a really great company but its policy. I have to cath about every 4 hours so its really not a big deal as I cannot feel that area.....grrrrrrr...I have fresh real urine, my family members. I have it in the frig for use tomorrow. I guess i am wondering if by the time I take the test, will there be any of my own urine in there to make me fail. This is the only thing I can think of that could work in my situation. Looking for thoughts.
