SCREENING PROCEDURE ONLY. Positives are not confirmed except where established by Laboratory policy. For other specimens, confirmation testing must be ordered by the physician. The Laboratory recommends that no legal action be taken on a positive screen result without confirmatory testing being performed.


Screening procedures generally target only one or a few specific drugs of a given class. Other drugs of the class may or may not cross react. Comprehensive Drug Screen may detect drugs not detected by this screening procedure.


pH and SG testing are performed to evaluate specimen integrity. Results outside the indicated ranges may or may not indicate an attempt by the patient to adulterate or otherwise compromise the specimen. Repeat testing on a new collection may be indicated if there is a question as to specimen integrity.


All urine drug screen specimens are stored for 10 days. Contact the Toxicology laboratory at 267-2780 for questions about confirmation testing, cross reactivity, Comprehensive Drug Screen, or specimen integrity testing.
