🧪 Specimens Used

We offer a variety of test types to meet your needs:

• Urine: Most common and widely accepted for workplace testing
• Saliva (Oral Fluid): Non-invasive, ideal for recent-use detection
• Hair: Long detection window, useful for long-term screening
• Sweat or Blood (limited use): Specialized circumstances

⚖️ Cut-Off Levels & Detection Periods

Understanding what a test can (and cannot) detect is crucial. Each drug and test type has its own cut-off level—the concentration at which a result is considered positive—and detection window, or how long a substance can be identified after use.

This matrix summarizes substances commonly screened using urine, oral fluid, and hair. Use this reference to determine the right panel and specimen for your compliance or workplace testing needs.
