This test is done to detect the presence of antibodies (IgG) against the Epstein-Barr virus (EBV) in the blood. It is used to confirm a past infection with EBV and to determine if a person has immunity to EBV.
When this test is required
The test may be requested when a person has symptoms suggestive of an EBV infection or when a person’s immune status needs to be determined, such as before an organ transplant.
What the Test Detects
The test detects the presence of IgG antibodies against the Epstein-Barr virus (EBV) in the blood. These antibodies are produced by the immune system in response to an infection with EBV, and they remain in the blood for life, providing immunity against future infections.
Preparation for the Test
No special preparation is usually required for this test. However, it is recommended to inform the doctor about any medications, supplements, or health conditions that may affect the test results.
Sample Requirements
The test requires a blood sample, which is usually collected from a vein in the arm.
Additional Notes
The test does not distinguish between a recent or a remote EBV infection. A positive test result does not indicate the presence of an active infection or the development of EBV-related diseases.
