A. Pass a small amount of urine into the toilet and then collect the specimen. This technique ensures that bacteria or debris from the urethra are flushed out before the sample is collected, providing a clean-catch specimen for analysis.

B. Void until the bladder is almost empty and then collect the end portion: This would result in a less accurate sample, as bacteria or debris might accumulate.

C. Let a few drops of urine dribble into the specimen cup: This does not provide enough urine for analysis.

D. Begin voiding into the specimen cup: This may contaminate the sample with bacteria from the external genitalia.
