What is this test?

This test looks for neutralizing antibodies against Duck Hepatitis Virus 2 (DHV-2) in your blood serum. Neutralizing antibodies are proteins produced by your immune system that can block or neutralize the virus, preventing it from infecting cells. The test uses a neutralization assay, which is a laboratory method that checks whether antibodies in your blood can prevent the virus from causing infection in cell cultures.

How is the test performed?

A healthcare professional will draw a blood sample from a vein in your arm. This blood sample will be sent to a laboratory where it will be processed to separate the serum (the liquid part of blood without cells). The serum is then tested using neutralization techniques to detect the presence and level of neutralizing antibodies against DHV-2.

What do the results mean?

A positive result means that neutralizing antibodies against Duck Hepatitis Virus 2 were detected in your serum, indicating previous exposure to the virus or vaccination. A negative result means no antibodies were detected, suggesting no prior exposure. Your healthcare provider will interpret these results in the context of your overall health and medical history.

Reference range

Negative: <1:8 titer; Positive: ≥1:8 titer. Presence of neutralizing antibodies indicates prior exposure to Duck hepatitis virus 2.N/A

Specimen: serum

No special preparation required. Standard venipuncture procedures apply.

Frequently asked questions

Is Duck Hepatitis Virus 2 dangerous to humans?
Duck Hepatitis Virus 2 (DHV-2) is a virus that primarily affects ducks and is not known to cause disease in humans. It is classified as an avian virus, and there is no documented evidence of DHV-2 infection in humans.
Why would this test be ordered?
This test may be ordered in veterinary diagnostic settings to monitor exposure in duck populations, or in specialized research contexts. If ordered for a human patient, it may be part of specific research studies or immune response investigations. Discuss the reason for this test with your healthcare provider.
Do I need to prepare for this test?
No special preparation is typically needed for this blood test. You should follow any instructions provided by your healthcare provider, such as fasting requirements if specified. The test simply requires a standard blood draw.
Are there any risks from the blood draw?
The risks are minimal and include slight pain or bruising at the injection site, lightheadedness, and in rare cases, infection. These risks are the same as with any standard blood draw.
