Anti-VCA IgM

EBV Viral Capsid Antigen Antibody IgM

What's

Anti-VCA IgM

Anti-VCA IgM is a special protein created by your body's defense system in response to an infection with the Epstein-Barr Virus (EBV). This virus is quite common and can lead to conditions like mononucleosis. The term "IgM" refers to the specific kind of protein, which is usually the first one your body makes when it comes across a new harmful invader. The "VCA" part of the name stands for "viral capsid antigen," a part of the EBV that the protein recognizes and attacks. In simple terms, finding Anti-VCA IgM in your blood is like a signal that your body's defense system is currently working to fight off the EBV.

If Your Levels Are High

Elevated levels of Anti-VCA IgM might mean that your body is actively fighting off an Epstein-Barr Virus (EBV) infection. IgM antibodies are usually the first warriors your immune system sends out when it meets a new harmful invader. So, finding high levels of these antibodies in your blood suggests that your body's defense system is currently battling the virus. Some possible reasons for increased Anti-VCA IgM levels include recent vaccinations, other infections, or conditions related to EBV, such as mononucleosis. Keep in mind that certain medications or external factors could also influence these levels.

Symptoms of High Levels

Symptoms of high levels of Anti-VCA IgM may include fatigue, fever, sore throat, swollen lymph nodes, and a general feeling of being unwell, which are common signs of an active EBV infection.

If Your Levels are Low

Low levels of Anti-VCA IgM might mean that your body isn't actively fighting an Epstein-Barr Virus (EBV) infection right now. This could be because you haven't come across the virus, or maybe your body already dealt with the infection and the amount of this specific antibody has gone down. Sometimes, certain medications or health issues that weaken the immune system can also lead to lower levels of Anti-VCA IgM. It's worth noting that your body might be using other types of antibodies to fight the virus, as everyone's immune response can be different.

Symptoms of Low Levels

Symptoms of low levels of Anti-VCA IgM are typically non-existent, as this is an indicator of the immune system's response to a virus rather than a condition with its own symptoms.

Test for

EBV Viral Capsid Antigen Antibody IgM

Epstein-Barr Evaluation by Access Med Labs

Serum

The Epstein-Barr Evaluation assesses several antibodies to the Epstein-Barr virus (EBV). It is performed to confirm active, past, or indeterminate infection for EBV-associated infectious mononucleosis.

Epstein-Barr Virus (EBV) Panel by Immunosciences Lab, Inc.

Serum

EBV contributes to more than 30 autoimmune disorders. Detection of IgG or IgM antibodies to various EBV antigens indicates either past infection, primary reactivation, or re-infection with Epstein-Barr Virus or Herpes Type 4.

Epstein-Barr Viral Capsid Ag, IgM by Access Med Labs

Serum

This test measures IgM antibodies to EBV viral capsid antigen (VCA). It is used to aid in the diagnosis of infectious mononucleosis.

Long COVID Panel by Immunosciences Lab, Inc.

Serum

The Long COVID Panel is used to detect three major viruses (EBV, HHV-6, and SARS-CoV-2) associated with long COVID and autoimmunity. It has been found that increased levels of antibodies against EBV and HHV-6 correlate with the severity of long COVID.

Viral Panel Premier by Immunosciences Lab, Inc.

Serum

This panel measures antibodies against six different viruses (EBV, CMV, HSV-1, HSV-2, HHV-6, VZV) that are involved in different inflammatory autoimmune diseases, chronic fatigue syndrome or myalgic encephalitis, neurodegenerative disorders such as Alzheimer’s and Parkinson’s, and neurological disorders such as Guillain-Barré syndrome and multiple sclerosis. Reactivation of these viruses is a major driver in increasing the severity of symptoms in patients with COVID-19. The test confirms immunological memory against Varicella zoster (VZV), the causative agent for shingles.
