Today we’d like to take some time and answer one of the questions we get asked most often. So you’ve purchased a home drug test, followed all the directions and provided your sample. You wait 10 minutes and you interpret the test. When you view the results, you have a faint line adjacent to the Test (T) region of the strip. What does this mean?
What’s a faint line indicate?
First off, a faint line is a negative result. It typically means there is some drug present in your system, but not enough to trigger a positive result. For example, if you use our THC 15 ng/mL test and your results show a faint line, this means your levels are below 15 ng/mL, which is considered very low. Most laboratory drug screens test THC at the 50 ng/mL level, so in this example you would pass the test. The best thing to do is not to over worry about a faint line. For a positive result, the line should appear next to the “C” and not the “T”.
A faint line could also mean you’ve got something else in your urine. It could be a urine sample that has a the wrong pH level, too much protein, high levels of sediment, a low specific gravity because of over-hydration or odd color due to medication.
In addition, all urine home drug tests have a shelf life. If your test is expired, it could cause a faint line.
