In the case of urinary tuberculosis,definitive diagnosis requires the recovery of acid-fast bacilli (AFB)from the urine.Early morning voided urine specimens in sterile containers should be submitted daily for at least 3 days.The procedure for collection is the same as that used to collect a clean-catch midstream urine specimen for routine culture.Because of excessive dilution,higher contamination,and difficulty in concentrating,24-hour urine specimens are undesirable.
