Can a dog test positive for Lyme disease and not have it?

A dog that tests positive for the Lyme bacteria on a blood test, however, doesn’t necessarily have Lyme disease and don’t necessarily need to be treated. Veterinarians will routinely screen for exposure to Lyme bacteria.

Does Lyme disease show up in regular blood work?

You do not usually need tests to show that you have Lyme disease. In most cases, there’s a clear sign of Lyme disease—a painless, spreading rash that often grows to look like a bull’s eye. If you have this rash, and you recently had a tick bite or were in an area known for Lyme disease, you don’t need a test.

What happens if your dog test positive for Lyme disease?

Once your pet is Lyme positive it is important to monitor for clinical signs such as lameness, swollen joints, fever, lethargy and decreased appetite. If these signs are noted it is possible that Lyme is the culprit; however, other causes can often be identified.

What can cause a false positive Lyme test?

Infection with other diseases, including some tickborne diseases, or some viral, bacterial, or autoimmune diseases, can result in false positive test results. Some tests give results for two types of antibody, IgM and IgG. Positive IgM results should be disregarded if the patient has been ill for more than 30 days.

What is the most accurate test for Lyme disease?

A blood test does not only detect Lyme disease; it is the most accurate and preferred test for diagnosing the disease. If a patient with Lyme disease shows signs that the central nervous system has been affected by the disease, western blot testing on the cerebrospinal fluid (CSF) can be performed.

Can you get a false positive for Lyme?

A positive result means that Borrelia antibodies were found and that you may have had or have Lyme disease. False-positive results sometimes do occur. This means the test could say you have the infection when you don’t.

Can you test for Lyme disease years later?

Your immune system continues to make the antibodies for months or years after the infection is gone. This means that once your blood tests positive, it will continue to test positive for months to years even though the bacteria are no longer present.

Can a light positive Lyme test be negative?

A light positive is still a positive, according to IDEXX, the SNAP test manufacturer. The IDEXX website notes the amount of antibody or antigen is different from dog to dog and “any color development in any of the sample spots indicates a positive result.” In other words, even if the coloration on the sample is faint, it’s positive.

Where can I get a blood test for Lyme disease?

The test can be done by your veterinarian in-clinic or the blood sample can be sent to an outside laboratory for testing. If the C6 test is positive, what is the next step? A positive C6 test means antibodies to C6 were found. The next step is to do a QC6 test, which determines if the levels of antibody are high enough to justify treatment.
