Dengue Fever IgG/IgM Antibody Test
What is a Dengue Fever IgG/IgM Antibody Test?
A dengue fever IgG/IgM antibody test is a blood test that can detect whether you have been infected with the dengue virus, which causes dengue fever. The test looks for two types of antibodies that your body produces in response to the virus: IgG and IgM.
IgG antibodies are produced by your body's immune system after you have been infected with the virus. They can stay in your blood for months or even years after you have recovered from the infection.
IgM antibodies are produced by your body's immune system in the early stages of an infection. They usually disappear from your blood within a few weeks after you have recovered from the infection.
The presence of IgG antibodies in your blood means that you have been infected with the dengue virus in the past. The presence of IgM antibodies in your blood means that you have a current or recent dengue virus infection.
Why is a Dengue Fever IgG/IgM Antibody Test Done?
A dengue fever IgG/IgM antibody test may be done to:
Diagnose a current dengue virus infection
Determine if you have been infected with the dengue virus in the past
Determine if you are immune to the dengue virus
How is a Dengue Fever IgG/IgM Antibody Test Done?
A dengue fever IgG/IgM antibody test is a simple blood test. A healthcare professional will draw a small amount of blood from a vein in your arm and send it to a laboratory for testing.
What Do the Results of a Dengue Fever IgG/IgM Antibody Test Mean?
The results of a dengue fever IgG/IgM antibody test are usually reported as follows:
Negative for both IgG and IgM antibodies: You have not been infected with the dengue virus.
Positive for IgG antibodies only: You have been infected with the dengue virus in the past.
Positive for IgM antibodies only: You have a current or recent dengue virus infection.
Positive for both IgG and IgM antibodies: You have a current or recent dengue virus infection.
What are the Limitations of a Dengue Fever IgG/IgM Antibody Test?
A dengue fever IgG/IgM antibody test is not always able to detect all cases of dengue virus infection. The test may be less accurate in the early stages of an infection, when IgM antibodies may not yet be present in the blood. The test may also be less accurate in people who have been vaccinated against dengue fever.
What are the Risks of a Dengue Fever IgG/IgM Antibody Test?
A dengue fever IgG/IgM antibody test is a safe procedure with few risks. The most common risk is bleeding or bruising at the site of the blood draw.
What Do I Do if I Test Positive for Dengue Virus?
If you test positive for dengue virus, your healthcare provider will discuss your treatment options with you. Treatment for dengue virus infection usually involves rest, fluids, and pain relievers. In severe cases, hospitalization may be necessary.
How Can I Prevent Dengue Fever?
There is no vaccine to prevent dengue fever, but there are steps you can take to reduce your risk of infection:
Use insect repellent when you are in areas where dengue fever is common.
Wear long sleeves and pants when you are in areas where dengue fever is common.
Use mosquito nets when you are sleeping in areas where dengue fever is common.
Empty standing water from around your home, as this can be a breeding ground for mosquitoes.
If you are traveling to an area where dengue fever is common, talk to your healthcare provider about taking preventive medications.
