HESKA Solo Step FH Feline Heartworm Test Cassettes

2. Using the pipette, draw up the patient sample into the stem portion of the pipette. Do not fill the bulb (Figure 2).

3. Holding the pipette vertically, dispense 3 drops of the sample into the round sample well of the test cassette (Figure 3).

4. Allow the test cassette to sit undisturbed for 5 minutes (Figure 4).

5. Read the results in the rectangular Results Window 5 minutes after applying plasma or serum. A blue line (Procedural Control Line) must appear on all samples, and a red line (Test Line) may or may not appear (Figure 5).

Interpretation Of Test Results

Procedural Control Line (C): You must see a blue line within 5 minutes of adding serum or plasma for the test to be valid. This blue procedural control line indicates proper flow of the sample through the test cassette. If the blue line does not develop, the test is invalid and should be repeated. Discard the test cassette, and repeat the test with a new test cassette.

Test Line (T): Any visible red line within 5 minutes of adding serum or plasma indicates a positive result. Antibodies to D. immitis are present. This means one or more of the following:

● Adult heartworms are present in the heart and/or pulmonary arteries.

● The cat is infected with late L4 or adult worm(s).

● Heartworm infection has been cleared, but antibodies are still present.

● Ectopic heartworm infection may be present.

In the presence of suggestive clinical signs and other supportive diagnostic data (e.g., radiographic findings, echo-cardiographic findings, etc.), a positive result will help confirm cardiovascular heartworm disease.

No red line within 5 minutes of adding serum or plasma indicates a negative test result. There are no antibodies to D. immitis present. This means one of the following:

● The cat is not infected with D. immitis.

● The cat was infected less than 60 days prior to collection of the sample. The dog is infected with adult male worms only.

If a negative result is obtained and clinical signs are present, a retest within 2-3 months is recommended. Additional diagnostic tests should be employed to rule out other causes of the clinical signs.

Sample Collection And Storage

Plasma: Collect an anticoagulated blood sample using standard clinical laboratory procedures. Separate plasma by centrifugation. Plasma samples may be stored refrigerated (2°-8°C) for up to 72 hours; for longer storage, freeze at or below -20°C in vials with air-tight seals.

Serum: Collect and prepare serum samples using standard clinical laboratory procedures. Serum samples may be stored refrigerated (2°-8°C) for up to 72 hours; for longer storage, freeze at or below -20°C in vials with air-tight seals.

Precautions

1. Do not expose the test cassette to direct sunlight.

2. Do not use to test species other than cats.

3. After 10 minutes, a very faint red line may appear in the Results Window with samples from some cats which are negative for heartworm infection.

4. Do not use the test cassette more than once.

5. Use the test cassette immediately after opening the foil pouch.

Storage and Stability

1. Store at room temperature (15°-30°C [59°-86°F]).

2. See package for expiration date.
