Chikungunya Virus IgG Antibody, Serum (Quantitative)
This test measures the level of antibodies in your blood that your immune system produces in response to a chikungunya virus infection. Antibodies help your body fight off infections.

What Does This Test Measure?
The test looks for IgG antibodies specific to chikungunya virus. IgG antibodies are a type of immune protein that your body makes after recovering from an infection or after vaccination. They provide long-term immunity. This test is used to confirm past exposure to the virus, not to diagnose an active infection.
Why Might You Need This Test?
A chikungunya virus IgG antibody test may be recommended if you have symptoms like joint pain, fever, or rash that suggest chikungunya infection, especially if you traveled to or lived in an area where the virus is common. It can help determine if you’ve had the virus before, which may be important for future health decisions or travel planning.
How Is the Test Performed?
A blood sample is taken from a vein in your arm. The sample is sent to a lab where it is tested for the presence of IgG antibodies using a sensitive immunoassay method. The lab will analyze the sample to determine antibody levels.
What Are the Results?
Results are reported as either positive or negative for IgG antibodies. A positive result means your body has produced antibodies against chikungunya virus, indicating past infection. A negative result means no detectable antibodies were found at the time of testing.
Reference range
Negative: <1:10 titer; Positive: ≥1:10 titer. A four-fold rise in titer between acute (1st specimen) and convalescent (2nd specimen) specimens collected 2-4 weeks apart is considered diagnostically significant.N/A
No special patient preparation required. Specimen should be collected as the acute phase (1st specimen) ideally within the first week of symptom onset for optimal paired serology interpretation.
Clinical interpretation
How abnormal results are interpreted and what conditions they suggest.
A positive IgG antibody test confirms that you have been exposed to chikungunya virus at some point. This can be useful for understanding your immune response, planning future travel to endemic regions, or assessing risk for future infections. It does not indicate whether you currently have an active infection, as IgG antibodies develop after recovery. If you suspect an active infection, other diagnostic tests may be needed.
