C. Fasting sample
D. 24-hour



Answer :

Final answer:

Clean-catch midstream urine specimens collected in a sterile container are best for bacterial culture testing due to minimizing external genital bacteria and enabling accurate culture for diagnosing UTIs.


Explanation:

Clean-catch midstream urine specimens collected in a sterile container are best for bacterial culture testing. This method involves letting some urine go before collecting a sample, which helps minimize external genital bacteria, ensuring a more accurate culture. Urine cultures diagnose urinary tract infections by determining the presence of bacteria; E. coli is a common culprit identified via selective and differential media like EMB.
