How to Use an 18 Panel Drug Screen Cup?
- Collect the Sample
- Remove the urine drug test cup from its sealed pouch and use it immediately for best results.
- Wait and Verify Temperature
- Timing: After 2–4 minutes, check the urine sample’s temperature. Temperature Verification: Look for the green dot on the temperature strip. A green dot will appear next to the corresponding temperature line, confirming that the specimen is within the proper range.
- Read the Results
- When ready to interpret the results, peel off the label from 18 Panel Drug Screen. Timing is crucial: Read the results within 5 minutes of testing. Do not read after 8 minutes, as results may no longer be accurate.
