Dengue is a viral infection that is transmitted by mosquitoes. IgG and IgM are the antibodies that are produced by the immune system in response to an infection. This tests detects the presence of these antibodies in case of exposure to dengue. You can order this test if you have signs and symptoms associated with dengue following travel to tropical locations where the virus is present. Some of the signs and symptoms include sudden high fever, headaches or pain behind the eyes, bone or joint pains, easy bruising.
The Dengue Fever IgM & IgG Antibody Test is a blood test used to detect antibodies produced by the immune system in response to the dengue virus. It helps diagnose if a person has recently been infected with dengue or has had past exposure to the virus.
The test differentiates between IgM and IgG antibodies by their appearance at different stages of the infection. IgM antibodies are produced earlier, typically within a week after infection, while IgG antibodies appear later and can persist for long periods after the infection has resolved.
The test is performed to confirm a diagnosis of dengue fever during the early phase of infection when symptoms are present. It can also help determine if a person has been previously exposed to the dengue virus or is immune to certain strains.
Common symptoms of dengue fever include high fever, severe headache, joint and muscle pain, rash, nausea, vomiting, and in severe cases, bleeding and organ damage. However, not everyone infected with dengue virus will show symptoms.
The test is most effective when taken within the first few days of symptoms appearing, as it helps in detecting the initial immune response. However, it can still be performed later during the infection, depending on the presenting symptoms.
A positive IgM result typically suggests a recent dengue infection, usually within the previous 2-3 weeks. A positive IgG result indicates previous exposure to dengue virus or immunity. Negative results for both IgM and IgG antibodies usually point to the absence of a dengue infection.
The Dengue Fever IgM & IgG Antibody Test is specific for dengue antibodies, but it may cross-react with antibodies from other similar infections like Zika and chikungunya. Further testing and clinical evaluation may be required to establish a definitive diagnosis.
The test is a simple blood draw and is generally considered safe. However, some risks associated with blood draws, such as minor bruising, bleeding, or infection at the site, may occur in rare cases.
