AB Cotton wool balls have been used to aid the collection of urine from infants. Concentrations of two urinary proteins, albumin and retinol binding protein, decreased by 40 and 80% respectively within 15 minutes of contact with the cotton wool. Cotton wool balls should not be used when investigating proteinuria.
