If only a control line (C) is visible, the test result is negative (no PP12 and/or AFP were detected). If both the control line (C) and test line (AF) are visible, the test result is positive (PP12 and/or AFP was detected). If no lines are visible, or just the test line (AF) is visible, the test result is invalid and should be repeated. Darkness of the stripes may vary. The test is valid even if the stripes are faint. Do not interpret test results based on darkness of the stripes.
