4. Holding the Chase Buffer Bottle vertically, add 3 drops of the chase buffer into each sample well.
5. Read the results at 8 minutes. Do not read the results after 10 minutes. Colored lines that appear after 10 minutes are not diagnostic and should be ignored.

VI. INTERPRETATION OF TEST RESULTS
Positive Results
A test is positive if a colored line appears under the Lyme (L), Anaplasma (A), Heartworm (H), or Ehrlichia (E) areas and a line appears under the Control (C) area in the same row. Any intensity of the Test Line (L, A, H, or E) area should be considered positive. Colored lines may be lighter or darker than each other.
Negative Results
The test lines for each row are negative if only one line appears at the Control line (C) area on that row.
Invalid Results
The test row is invalid if no colored line appears at the Control line (C) area on a given row. Even if a colored line appears in the Test line (L, A, H, or E) areas, there must be a control line (C) on that same row.
