Urine via catheter is:
a. acceptable.
b. not acceptable.
B
Because indigenous anaerobes are often present in large numbers as normal flora on mucosal surfaces, even minimal contamination of a specimen can give misleading results. Specimens that are likely to be contaminated are unacceptable for anaerobic culture. Although a better specimen method than voided urine, catheterized urine may be contaminated with lower genitourinary tract flora. Material from the bladder for anaerobic culture is best obtained by aspiration using a needle and syringe.
