Because of the personal, occupational, and legal implications that accompany drug testing, laboratories that perform urine drug screenings (UDS) must be confident in their methodology and their ability to interpret screening results.

Read LabGuide 56 and be able to:

• Outline the methodologies used for qualitative urine drug screening
• Verify performance of FDA Approved qualitative methods
• Establish performance of non-FDA approved qualitative methods
• Summarize additional applicable requirements
