Understanding Faint Lines.

What causes a faint T-line?

Simply answered, here are some possible reasons for a faint T-line:

The use of detox/cleansers, CBD, drinking a substantial amount of fluid prior to testing, or tampering/diluting the urine sample with a substance. See our  “How to Ensure an Accurate Test Result” page for more information.

  • The test was not left in the urine sample long enough.
  • There is not enough THC in the system to trigger a positive result; a small trace amount in the urine sample may cause a faint line.
  • Low detection level test may cause a faint T-line (ie. THC 20 ng/mL test, THC 15 ng/mL, COC 150 ng/mL).
  • Taking a medication that is chemically similar to the drug being screened.
  • The test is past its expiration date.
