First Check 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 DrugTest.
- 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 First Check®
Home Drug Test 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 for 30 minutes before testing.
- 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
