Answer

Urine specimen collection

  • A midstream, clean-catch specimen may be obtained from children who have urinary control

  • Suprapubic aspiration or urethral catheterization should be used in the infant or child unable to void on request

Suprapubic aspiration is the method of choice for obtaining urine from the following patients:

  • Uncircumcised boys with a redundant or tight foreskin

  • Girls with tight labial adhesions,

  • Children of either sex with clinically significant periurethral irritation

Culture of a urine specimen from a sterile bag attached to the perineal area has a false-positive rate too high to be suitable for diagnosing UTI; however, a negative culture is strong evidence that UTI is absent. [3]
