SNAP 4Dx Plus Test KitThis treatment applies to the following species:
Canine Heartworm Antigen-Anaplasma Phagocytophilum-Platys-Borrelia Burgdorferi-Ehrlichia Canis-Ewingii Antibody Test Kit
For veterinary use only.
SNAP* 4DX* Plus Test
In vitro diagnostics for the detection of Dirofilaria immitis antigen, antibody to Anaplasma phagocytophilum, antibody to Anaplasma platys, antibody to Borrelia burgdoferi, antibody to Ehrilichia canis, and antibody to Ehrlichia ewingii in canine serum, plasma, or whole blood.
Precautions And Warnings
● All wastes 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.
● Male-only heartworm infections typically produce antigen levels that are below the detection capability of this antigen test.
● WARNING: Conjugate - H316/P332+P313/EUH208. Causes mild skin irritation. If skin irritation occurs: Get medical advice/attention. Contains Kathon. May produce an allergic reaction.
● Store at 2-8°C until expiration date.
● SNAP devices and reagents can be stored at room temperature (18-25°C) for 90 days or until the expiration date, whichever occurs first.
● After SNAP devices and reagents are removed from 2-8°C for more than 24 hours, the expiration date is 90 days or the printed expiration date, whichever occurs first. If the 90-day expiration date occurs prior to the printed expiration date, record the new date in the space provided on the kit.
1 or 5 bottles Anti-D. immitis/Anaplasma spp./B. burgdorferi/E. canis/E. ewingii: HRPO conjugate (preserved with gentamicin and Kathon)
5, 15, or 30
Reagents contained in each device:
Wash solution (preserved with Kathon)
Other components: transfer pipettes, sample tubes, and reagent rack
● Samples must be at room temperature (18-25°C) before beginning the test procedure.
● Serum, plasma, or anti-coagulated whole blood (eg. 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 lypemic samples will not affect results.
1. If stored in a refrigerator, allow all components to equilibrate at room temperature (18-25°C) for 30 minutes before use. Do not heat.
2. Using the pipette 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 tube 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 button after the sample has flowed across the result window.
7. Read the test result at 8 minutes.
Note: The positive control may develop sooner, but results are not complete until 8 minutes.
Interpreting The Test Results
Any color development in the sample spots indicates the presence of Dirofilaria immitis antigen, A. phagocytophilum antibody, A. platys antibody, B. burgdorferi antibody, E. canis antibody, or E. ewingii antibody in the sample.
● The A. phagocytophilum/A. platys spot cannot differentiate between the two species: a positive result indicates presence of antibodies to A. phagocytophilum and/or A. platys.
● The E. canis/E. ewingii spot cannot differentiate between the two species: a positive result indicates presence of antibodies to E. canis and/or E. ewingii.
● In a low percentage of samples (0.027% as reported), interfering substances in the patient’s blood can cause all spots on the device to react as positive. In this event, the sample should be re-assayed as plasma or serum to reduce the likelihood of interference.
Only positive control spot develops color.
● Background-If the sample is allowed to flow past the activation circle, background color may result. Some background color is normal. However, if colored background obscures the test result, repeat the test.
● No color development-If the positive control does not develop color, repeat the test.
Idexx Snapshot Dx* Analyzer
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.
Borrelia burgdorferi vaccine cross-reactivity-The Borrelia burgdorferi assay detects antibodies induced as a result of natural infection with the organism and not following immunization with the following vaccines:
Recombitek® Lyme, LymeVax®, and Galaxy® Lyme and Nobivac® Lyme.
