This list is not necessarily inclusive of all possible drugs that could be identified.
This test is intended for use in the clinical management of patients. It is not intended for use in employment related testing.
Not the preferred method, as the detection window is shorter and detectable drugs levels lower than in urine specimens. Should only be used for patients that are not producing urine. Test of choice for optimal detection is Compliance Drug Analysis, 8742/LAB8742
