How do I know if the First Check Home Drug Test worked properly? What if I am unsure of the result?
The test is working properly as long as a red or pink colored line appears next to the word Control or the letter C (depending on the test you have purchased). The result is Negative when a red or pink colored line appears next to the word Drug or the drug abbreviation (depending on the test you have purchased). The result is Preliminary Positive when NO line appears next to the word Drug or the drug abbreviation (depending on the test you have purchased). If you have questions about your results call 1-888-788-5716 to speak with one of our First Check representatives. If you are unsure about your results please re-test using a new First Check Home Drug Test.
