If adulteration is included on the test cup, read the specimen validity test

(S.V.T.), between 3 and 5 minutes. Compare the colors on the adulteration

strip to enclosed color chart. If the results indicate adulteration, do not read

the drug test results.



Read the drug test results at 5 minutes. Do not interpret results after 60 minutes as false results may occur.



NEGATIVE

The control line must be colored to indicate the test is valid. Any visible line, even a faint line, indicates a negative result.




POSITIVE

The control line must be colored to indicate the test is valid. The test area must be snow white to be considered positive.


INVALID

When there is no line in the control line area, the result is invalid. If an invalid result is obtained repeat the test using a new test device.
