Specimen Handling
Additional Information	Urine is the required specimen for comprehensive drug screens as it is most sensitive and optimized for our methodology. FDSU TAT: up to 5 days Refer to Clinical Toxicology testing section C for a complete list of drugs which can be identified. FDSU is intended for routine priority testing and requires a completed Medical Drug History Form #DS3601 .
