- Will toilet paper contaminate a urine sample?
A clean collection device is necessary for accurate lab evaluation. Toilet paper will contaminate the urine and produce an inaccurate result.
- How do you pass a 24 hour urine test?
All urine, after the first flushed specimen, must be saved, stored, and kept cold. This means keeping it either on ice or in a refrigerator for the next 24 hours. Try to urinate again at the same time, 24 hours after the start time, to finish the collection process. If you can't urinate at this time, it is OK.
