thank you. these are urine tests for her nephrologist. i don't know if they are checking for infection. they are checking her kidney levels via blood and urine tests. we did this 3 months ago., too. my mom is so upset every time we have to get a specimen.... i asked the lab about my problem, and they couldn't help me. i asked for a hat and they stated they could become contaminated and you wouldn't get a sterile specimen. i'm wondering if there is a sterile hat or something. i had to clean her commode and around it smell of urine and got on her clothes at home. we didn't get much. finally, at the lab, i went into bathroom with her and we got one. it was messy all over my hand. please help. thank you
