• A CONTROL Line should always appear as proof the test has worked, and that the sample is suitable for testing.
  • No line on the test area is POSITIVE (or non-negative). We advise that you send this sample to the lab for further testing.
  • Any line, no matter how faint, on the test area is a NEGATIVE result. (See faint lines information.)
  • It is normal for lines to develop at different rates, and have different intensities.
  • A negative result can appear in under a minute.
  • To read a positive result you will need to wait the full five minutes before reading the results.
  • Tests should not be read after 10 minutes.
