Ordering the test. A doctor can order EBV specific tests when he or she feels that an infection with EBV is likely. The tests will look for indications that the body is fighting off the EBV virus. There are two tests that the doctor may order. An antibody test will determine if the immune system is producing specific cells to fight the virus. Another test can look for a specific white blood cell that the body produces in response to an EBV infection. Both of these tests are simple blood tests that can be done at any lab.
