How to Use a 18 Panel Drug Test 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. Timing is crucial: Read the results within 5 minutes of testing. Do not read after 8 minutes, as results may no longer be accurate.

Adulterants test
Adulterants testing with these strips is a process that searches for any kind of tampering with a urine sample from the donor.
Those additional ADLTX strips will further increase the minimum chance that the sample can be changed or anyhow tempered with before testing.
Some of the commonly used adulterants in urine drug testing are:
- Table salt
- Household vinegar
- Liquid laundry bleach
- Lemon juice.
- Diluted urine (creatinine below 15 mg/mL).
- Visine eye drops
The urine drug testing cups with adulteration drug test are designed to be user-friendly and reliable.
