Dip cards are designed to allow the user to test in 3 easy steps!     NEGATIVE The control line must be colored to indicate the test is valid. Any visible line, even a faint line, indicates a negative result.  POSITIVE The control line must be colored to indicate the test is valid. The test area must be snow white to be considered positive.  INVALID When there is no line in the control line area, the result is invalid. If an invalid result is obtained repeat the test using a new test device.  |
