Epstein-Barr Virus Antibody Panel - Primary infection by EBV causes infectious mononucleosis, usually a self-limiting disease in children and young adults. Infection with EBV can cause lymphoproliferative disorders including tumors. VCA-IgM is typically detectable at clinical presentation, then declines to undetectable levels within a month in young children and within 3 months in other. Epstein-Barr virus (EBV) antibodies are a group of tests that are requested to help diagnose a current, recent, or past EBV infection. EBV is a member of the herpes virus family. Passed through the saliva, the virus causes an infection that is very common. As many as 95% of people in the United Kingdom will have been infected by EBV by the time they are 40 years old Epstein-Barr Virus (EBV) antibodies are used to help diagnose glandular fever if you are symptomatic but have a negative monospot test. Requesting serology testing for EBV antibodies will include: Viral capsid antigen (VCA)-IgM, and VCA-IgG — to detect a current or recent infection. If VCA-IgG is detected then Epstein Barr nuclear antigen.

Positive IgM and IgG tests for Dengue antibodies detected in a sample means that the patient became infected with dengue virus within recent weeks. IgG as a sero-marker of Dengue infection. If the IgG is positive but the IgM is low or negative, then it is likely that the patient had an infection sometime in the past CAEBV is a rare, but life-threatening, lymphoproliferative disorder with persistent infectious mononucleosis-like symptoms. Although the pathological findings lack distinctive histological features, EBER-ISH to identify EBV-infected cells and EBV-DNA viral load are critical in making the diagnosis of CAEBV Epstein-Barr antibody testing. The results of an EBV antibody test are usually ready within 3 days. The results of the antibody test to detect Epstein-Barr virus (EBV) are usually reported as positive (antibodies are present) or negative (antibodies are not present)

The elisa lyme test, which is the preliminary test, can have a false positive due to Epstein-Barr BUT absolutely NOT the Western Blot. The bands are the western blot test and each band represent as a whole, an organism. There are certain bands that pertain to the flagella which can be syphillis because they are also a spirochete, BUT you must. Heterophile antibody negative sera demonstrating VCA IgM and transient levels of antibody to early antigen are considered diagnostic for acute IM. In contrast, antibodies to EBNA appear late during IM infections, and IgG antibodies to EBNA may persist for years, even for life, and are indicative of the convalescent phase of IM infection
