3. Specimen collected at other times are acceptable.
Specimen Rejection:
1. Urine samples exceeding specimen stability.
2. Urine samples <2 mL in volume.
3. Urine samples below minimum fill line for BD vacutainers.
Males

2. Circumcised patients clean beginning of urethra with provided towelette.
3. Uncircumcised patients withdraw foreskin and clean beginning of urethra with provided antiseptic towelette.
4. Urinate a small amount into toilet, then collect a midstream portion of urine into container, void remainder into toilet.
5. Label container with patient’s name (first and last), date and actual time of collection, and type of specimen.
Females
1. Before beginning collection, wash hands with soap and water.
2. Thoroughly clean urethral area with soap and water or with provided antiseptic towelette.
3. While holding labia apart urinate a small amount into toilet, then collect a midstream portion of urine into container, void remainder into toilet.
4. Label container with patient’s name (first and last), date and actual time of collection, and type of specimen.
