EBV Ab VCA IgM
Epstein-Barr Virus (EBV) is a virus that is responsible for the disease mononucleosis. IgM is especially useful in determining if there is active disease, since this is the only time there will be CMV IgM antibodies present in the blood.
Epstein-Barr Virus (EBV) is a virus that is responsible for the disease mononucleosis. It causes mild to moderate infection and is quite common amongst the adult population. Most people do not experience symptoms, but in some instances can get very ill. There are different tests which can be performed for the detection of EBV. The viral capsid antigen IgM antibodies against CMV are the first antibodies to be produced during the disease duration. They are usually present in the blood for the first two to four weeks before it eventually drops to undetectable levels, after which, IgG antibodies take over their function. Therefore, IgM is especially useful in determining if there is active disease, since this is the only time there will be CMV IgM antibodies present in the blood.
This test is performed in following conditions such as:
• Lack of appetite
• Sore throat
• Swollen glands in the neck
• Weakness and sore muscles
Also Known As: Epstein Barr Viral Capsid Antigen Antibodies IgM
IgM antibodies are typically detectable within 2-3 weeks of infection but may be detectable earlier in some people. These antibodies will typically no longer be detectable 4-12 weeks after infection. These antibodies may be detectable for a longer period in adults.
Estimated Time Taken
Turnaround time for the EBV Abs VCA, IgM test is typically 2-3 business days.
