Urine: Collect urine samples in clean glass or plastic containers. Fresh urine specimens do not require any special handling or pretreatment, but an effort should be made to keep pipetted samples free of gross debris. Samples should be within the normal physiological pH range of 5‑8. No additives or preservatives are required. It is recommended that urine specimens be stored at 2‑8 °C and tested within 5 days of collection.
