Testing Tips for Yourself

First Check® Home Drug Tests are only as accurate as the urine sample being tested, so here are some tips to help ensure a reliable result.

  • Read the instructions COMPLETELY before taking the test and have a clock or timer available.
  • Wash and dry your hands thoroughly before taking a First Check® Home Drug Test.
  • Use first-morning urine when possible since it’s typically the most concentrated urine of the day, which makes it best for detecting any drugs that may be in the body.
  • Collect the urine sample before drinking anything in the morning. This will prevent having a diluted urine sample by drinking excessive amounts of fluid.
  • Ensure the First Check test is placed on a level, flat surface.
  • Do not touch the First Check test while the results are processing.
  • Be sure to read your results at 5 minutes but not after 10 minutes. Results are considered invalid after 10 minutes.
  • You may choose to refrigerate the sample for testing at a later time. When you are ready to take the test, remove the sample from the refrigerator and allow it to sit at room temperature.

Certain over-the-counter medications or prescription drugs may cross-react with the First Check® Home Drug Test and cause a preliminary positive result. For a complete list of substances which may cross-react with this test, click here.
