Children can obtain clean-catch urine samples, but they might find it easier with a sterile receptacle placed within the toilet for specimen collection. Pour the sample from the receptacle into a sterile collection cup. Then, with the lid in place on the cup, label the sample and send it to the laboratory for analysis. Do not squeeze samples from a wet diaper or pad, as the results are likely to be inaccurate. Some studies have demonstrated accuracy of some urine tests when urine is collected in a syringe from a disposable diaper.
