This project investigated the accuracy of laboratory results of urine samples collected from cotton balls as compared with samples collected from catheterization, preemie pampers and newborn pampers. Also, it examined the cotton ball's effect on the infant's skin upon its removal. Comparisons in test results were made concerning the Directigen test for Group B strep (GBS) and labstick analysis, using descriptive and inferential statistical analysis. The infants (21) who were tested for GBS using catheter and cotton ball samples yielded the same results.

Urine samples subjected to labstick analysis were obtained from 30 infants, the urine being extracted from preemie pampers, newborn pampers, and cotton balls placed in preemie pampers. Samples obtained from cotton balls and preemie pampers yielded equivalent results. However, significant differences were found in pH and specific gravity between newborn pamper samples and samples obtained from cotton balls or preemie pampers. No redness or skin breakdown was observed.
