Storage Instructions: N/A (Requirement not needed as this test can only be ordered on samples that have been submitted for drug screening)

Transportation Instructions: N/A (Requirement not needed as this test can only be ordered on samples that have been submitted for drug screening)

Test Methodology: Liquid chromatography/mass spectrometry or gas chromatography/mass spectrometry

Additional Information: Must have Department of Corrections (DOC) approval to perform test
