How likely is a false negative parvo test?
A recent study found that the Idexx SNAP test detected 80%, 78% and 77% of parvovirus 2a, 2b, and 2c respectively. As with any test, false results are possible. Negative results will occur later in the course of disease when virus is bound by antibody or no longer being shed.
What can cause a false negative parvo test?
False-negative: Because dogs begin shedding the virus in their feces within 4 to 5 days of exposure,1 the antigen test can produce a false-negative result if performed before shedding begins. False-positive: Because the parvovirus vaccine contains a modified-live virus, recent vaccination can affect testing.
Do you have to have a test for Parvo?
On the other hand, a test to confirm parvo may not really be necessary. The parvo virus causes severe illness. Since the condition is managed with supportive care rather than cured, it is not always necessary to run diagnostic tests. The treatment will likely be the same with or without a definite diagnosis.
Which is the most accurate test for canine parvovirus?
The CPV fecal PCR test detects small pieces of viral DNA that are specific to CPV in the stool of an infected dog. This test is very accurate (more so than CPV fecal ELISA), but requires that a fecal sample be sent to a laboratory that specializes in performing PCR-based testing, so it generally requires more time than a CPV fecal ELISA.
What happens to a dog when it is infected with Parvo?
If the combination of factors is just right and a dog does become infected, a specific sequence of events is begun as the virus attacks the body. What happens during infection? Once a dog or puppy is infected, there is an incubation period of three to seven days before the onset of first symptoms.
When did parvovirus type 2 first appear in dogs?
What causes parvovirus infection? The virus that causes the disease known as “parvo”, canine parvovirus type 2 (CPV), first emerged among dogs in Europe around 1976. By 1978 the virus had spread unchecked, causing a worldwide epidemic of myocarditis and inflammation in the intestines (gastroenteritis).
When to read the results of the SNAP Parvo test?
The test result must be read 8 minutes after the device is activated. The test does not contain stop solution, and after 8 minutes, color development that is not related to the sample may occur. Do not report results read after 8 minutes. Using the SNAP®Parvo Test with the SNAP Pro®
On the other hand, a test to confirm parvo may not really be necessary. The parvo virus causes severe illness.

What should every dog owner know about parvovirus?
Make sure all dogs in your household are vaccinated, and be very careful when socializing your puppy. Dog parks and other places where dogs congregate are potential sources of parvo, so plan on socializing your puppy in a less public environment. Socialization and training are very important for puppies.
How long does it take for Parvo to show in a puppy?
Puppies and adult dogs with parvo start shedding the virus within 4-to-5 days of exposure. Unfortunately for conscientious owners, this time period does not always coincide with the first parvo symptoms, which means dogs can be contagious before owners even realize that they are sick.
