Heartworm Antigen Test Kit

For veterinary use only.

SNAP* HTWM

In-vitro diagnostic for the semiquantitative detection of Dirofilaria immitis (D. immitis) antigen in canine and feline whole blood, serum or plasma.

Precautions and warnings

● All waste should be properly decontaminated prior to disposal.

● Do not mix components from kits with different serial numbers.

● Do not use a SNAP device that has been activated prior to the addition of sample.

● WARNING: Conjugate - H316/P332+P313/EUH208. Causes mild skin irritation. If skin irritation occurs: Get medical advice/attention. Contains ProClin™ 150. May produce an allergic reaction.

Storage

● Store at 2-25°C until expiration date.

● All components must be at room temperature (18-25°C) before running the test.

Sample information

● Samples must be at room temperature (18-25°C) before beginning test procedure.

● Serum, plasma or anticoagulated whole blood (e.g., EDTA, heparin), either fresh or stored at 2-8°C for up to one week, can be used.

● For longer storage, serum or plasma can be frozen (-20°C or colder) and then recentrifuged before use.

● Hemolyzed or lipemic samples will not affect test results.

Test procedure

1. If stored in a refrigerator, allow all components to equilibrate at room temperature (18-25°C) for 30 minutes. Do not heat.

2. Using the pipette that is provided, dispense 3 drops of sample into a new sample tube.

3. Holding the bottle vertical, add 4 drops of conjugate to the sample tube.

4. Cap the sample tube and mix it thoroughly by inverting it 3-5 times.

5. Place the device on a horizontal surface. Add the entire contents of the sample tube to the sample well, being careful not to splash the contents outside of the sample well.

The sample will flow across the result window, reaching the activation circle in 30-60 seconds. Some sample may remain in the sample well.

6. When color FIRST appears in the activation circle, push the activator firmly until it is flush with the device body.

Note: Some samples may not flow to the activation circle within 60 seconds, and, therefore, the circle may not turn color. In this case, press the activator after the sample has flowed across the result window.

7. Read test result at eight minutes.

Interpreting Test Results

Positive Result

Any amount of color development in the sample spots indicates a positive result and color intensity is proportional to the heartworm antigen concentration in the sample.

Low antigen levels

High antigen levels

Negative Result

Only the positive control spot develops color.

Invalid results

1. Negative Control (safeguard against false positives) - If color in the negative control spot is equal to or darker than the color in the sample spots, the result is invalid and the sample should be retested.

2. No Color Development - If the positive control does not develop color, repeat the test.

3. Background - If the sample is allowed to flow past the activate circle, background color may result. Some background color is normal. However, if colored background obscures test result, repeat the test.

Idexx Snapshot Dx* Analyzer

Canine test results can also be read using the SNAPshot Dx Analyzer. A complete description of how to enter patient data and read test results using the SNAPshot Dx Analyzer can be found in the SNAPshot Dx Analyzer Operator’s Guide.
