Can Blood Test Detect Distemper in Dogs?

Understanding Blood Tests for Canine Distemper

Blood tests can be used to detect canine distemper, but they are not always the most accurate method for diagnosing the disease. While blood tests can identify antibodies or antigens related to the Canine Distemper Virus (CDV), the results may not always be conclusive, especially in the early stages of infection. The gold standard for detecting CDV involves PCR testing and virus isolation. However, rapid blood tests, such as those offered by SaberVet, are useful for providing quicker results in clinical settings.

What is Canine Distemper?

Canine distemper is a contagious viral disease caused by the Canine Distemper Virus (CDV), affecting multiple systems within the dog’s body, including the respiratory, gastrointestinal, and nervous systems. It is primarily spread through respiratory secretions and contact with infected animals. Distemper can cause severe symptoms and, if untreated, may result in death.

Symptoms of Canine Distemper

Common symptoms of canine distemper include:

• Fever
• Discharge from eyes and nose
• Coughing and difficulty breathing
• Vomiting and diarrhea
• Neurological signs, including tremors and seizures

Because these symptoms overlap with other diseases, diagnostic tests are required to confirm the presence of CDV.

How Blood Tests Detect Canine Distemper

Blood tests for canine distemper typically focus on detecting either antibodies or antigens. Here’s how these tests work:

• Antibody Test: This test looks for antibodies produced by the immune system in response to CDV. A positive result indicates past exposure or vaccination. However, it may not confirm an active infection, especially if the dog was recently exposed.
• Antigen Test: This test detects the presence of the virus itself in the blood. A positive result indicates an active infection, but the test is less sensitive than PCR and may require confirmation with other diagnostic methods.

While these tests can be useful, they are generally not sufficient for definitive diagnosis, especially in the early stages of the disease.

Confirmatory Tests for Canine Distemper

In addition to blood tests, the gold standard tests for confirming canine distemper include:

• PCR Testing: This method amplifies the virus’s genetic material, making it easier to detect even small amounts of CDV in blood or other samples. PCR is highly sensitive and specific, making it ideal for early detection.
• Virus Isolation: This involves growing the virus in a laboratory setting to confirm its presence. While highly accurate, virus isolation is time-consuming and not typically used for routine diagnosis.

SaberVet Canine Distemper Virus Antibody and Antigen Rapid Tests

SaberVet offers rapid testing solutions for canine distemper, which can be used in the field or clinical settings to quickly identify CDV. These tests are designed to detect either the presence of CDV antibodies or antigens in a dog’s blood, serum, or plasma.

SaberVet Canine Distemper Virus Antigen Rapid Test

• Sample Type: Whole blood, serum, or plasma
• Results in: 10 minutes
• Technology: Immunochromatographic assay
• Benefits: Quick, non-invasive, and portable for on-site diagnostics

SaberVet Canine Distemper Virus Antibody Rapid Test

• Sample Type: Whole blood, serum, or plasma
• Results in: 10 minutes
• Technology: Immunochromatographic assay
• Benefits: Determines past exposure or vaccination status

How to Perform SaberVet’s Rapid Tests

1. Collect the required sample (blood, serum, or plasma) from the dog.
2. Apply the sample to the test device and add the buffer solution.
3. Wait for 10 minutes and interpret the result.

Reading the Test Results

• Positive: Two lines (test and control) indicate the presence of CDV.
• Negative: Only the control line appears, confirming no CDV detection.
• Invalid: No control line, requiring a retest.

Precautions for Accurate Blood Testing

For optimal accuracy, ensure the following precautions are followed:

• Use fresh, uncontaminated samples.
• Test at room temperature for the best results.
• Interpret results within the specified timeframe for accuracy.

Conclusion

While blood tests can provide some information about canine distemper, they are not the most reliable diagnostic tool on their own. PCR testing and virus isolation remain the gold standard for detecting CDV. Rapid antigen and antibody tests, such as those offered by SaberVet, provide fast results, but they should be used alongside more definitive diagnostic methods to confirm the presence of the virus.
