How do I interpret a NEGATIVE drug test result with the T-Cube?
A colored band must be visible in each control region (C) to indicate that the test is valid. If a colored band is visible in any of the Test Regions (T), it indicates that the concentration of the drug in the corresponding test zone is absent or below the detection limit of the test. Certain lines may appear lighter or thinner than other lines. ANY COLORED LINE VISIBLE IN THE TEST REGION (T), SHOULD BE INTERPRETED AS A NEGATIVE RESULT. NO MATTER HOW DARK OR FAINT
