What Is a Mononucleosis Spot Test? A mononucleosis spot (or Monospot) test is a blood test used to determine whether or not you are infected with the Epstein-Barr virus, which is the organism that causes infectious mononucleosis. Your doctor may order this test if you have symptoms of mononucleosis.
Mono tests include: 1  Monospot test (heterophil test). This quick screening test detects a type of antibody (heterophil antibody) that forms during certain infections. 2  EBV antibody test. For this test, a sample of blood is mixed with a substance that attaches to antibodies against EBV. A series of tests can detect different types of antibodies to help determine whether you were infected recently or sometime in the past.
