When you test every dog every year with the SNAP® 3Dx Test, you can provide valued benefits for your
patients, your clients and your practice, including:
-
Prevalence data—you'll learn what's prevalent in your area
-
With known prevalence, you have the data to support the use of prevention with dog owners
-
Positive tests identify dogs that require additional workups; dogs that would have gone
unnoticed in the past
|
|
|
-
Screening for disease allows you to find it in a subclinical state instead of waiting for these
dogs to come through the door with clinical signs
-
Negative results help you reinforce that owners' efforts and expenses are paying off,
especially with the prevalence data you generated to show they're in an endemic area
 |
|
|
"The [SNAP 3Dx] test has definitely increased revenues in my practice, but more importantly, we
have more satisfied clients because we can identify disease states earlier."

IDEXX SNAP 3Dx Test Benefits:
- Identify Lyme disease in clinically
and subclinically infected dogs.
-
This fast, in-house test specifically detects antibodies to E. canis,
the cause of canine ehrlichiosis.
- The SNAP® 3DX®
Heartworm Test delivers the most trusted results available.
1. Identify Lyme disease in clinically
and subclinically infected dogs.
The SNAP® 3DX® Test
identifies an antibody that is produced only as a result of a B. burgdorferi infection
(unlike IFA, which isn't specific for B. burgdorferi infection). The difference is the
unique, revolutionary C ELISA technology.
-
C identifies infection
The SNAP 3DX Test is based on detection of antibody to a highly specific, conserved,
immunodominant region of VIsE, a surface antigen, called C. Antibody
concentrations are believed to have a high correlation to the presence of viable spirochetes.
-
C wanes rapidly post-treatment
If left untreated, Lyme disease symptoms can become very serious. Studies have shown that
antibiotic therapy is beneficial to both clinically and subclinically infected dogs. C antibody declines rapidly after successful treatment and may be
well-suited to determine response to therapy.
-
C doesn't cross-react
-
Antibodies from currently available Lyme vaccine have been shown not to cross-react with
SNAP® Lyme antibody detection, so you can identify
infection in vaccinated dogs.
-
Because no Lyme vaccine is 100% effective, even vaccinated dogs should be tested for Lyme
disease during every annual screening visit.
-
The SNAP 3Dx Test offers superior sensitivity and specificity:
-
When you test before vaccinating, you won't be vaccinating subclinically Lyme-positive dogs
and giving owners a false sense of security.

2. This fast, in-house test specifically detects antibodies to E. canis,
the cause of canine ehrlichiosis.
Early detection is the most effective way to protect
your patients because the prognosis is good for early-stage infection, but variable-to-guarded for
chronic infections.
The SNAP 3DX Test allows for inexpensive in-house E. canis screening, helping you
diagnose sooner. Therefore, treatment can be initiated to prevent the dog from progressing into
later stages, where the illness is more difficult to manage.
Ehrlichia specificity is high on the SNAP 3Dx Test.
The SNAP 3Dx Test uses an E. canis-specific peptide for accurate, reliable confimation
of exposure to E. canis, with a specificity of 99%.

3. The SNAP® 3DX®
Heartworm Test delivers the most trusted results available.
With the superior accuracy of ELISA
technology, you can:
-
Find low worm-burden cases sooner and more often, and begin treatment when you can do the
most good. It's the only test proven to be more sensitive than other in-house tests
in detecting low worm-burden.
-
Count on flexibility to test your way, because ELISA is equally
effective on whole blood, serum or plasma.
-
Interpret the test results easily every time—it's the only pet-side
test with a built-in wash step and amplification of a positive reaction, making
positives easier to detect.
The SNAP 3Dx Test reinforces your current heartworm protocol of "diagnose, prevent and
treat"—the cornerstones of building your practice—because it:
-
Delivers the hightest sensitivity of all currently available in-house assays
-
Is easy to interpret, instilling confidence that a heartworm-positive dog is correctly
diagnosed
-
Offers convenient, patient-ready, room-temperature storage
