What test is used to diagnose an Epstein-Barr virus EBV infection?
Heterophile antibody testing (also known as Monospot) is often used as a first-line test in the diagnosis of Epstein-Barr virus (EBV) infectious mononucleosis (IM).
Which blood cells are increased in an Epstein-Barr infection?
Hematological System. EBV infection can affect a person’s blood and bone marrow. The virus can cause the body to produce an excessive number of white blood cells called lymphocytes (lymphocytosis).
What do high EBV antibodies mean?
Some types of EBV antibodies are present in higher numbers during an active infection. Other EBV antibodies mean that you had an infection in the past. Depending on the type of antibodies your test shows, your healthcare provider can find out more about what is causing your illness.
What diagnostic test would be most appropriate to determine if a latent Epstein-Barr virus infection has reactivated in a persistently infected patient?
The Centers for Disease Control and Prevention (CDC) recommend ordering several tests to help determine whether a person is susceptible to EBV or to detect a recent infection or a prior infection, or a reactivated EBV infection. These tests include: Viral capsid antigen (VCA)-IgM. VCA-IgG.
Can Epstein-Barr affect red blood cells?
Hemophagocytic syndrome (HPS) is a fatal complication frequently associated with viral infections. In childhood HPS, Epstein-Barr virus (EBV) is the major causative agent, and red blood cells (RBCs) are predominantly phagocytosed by macrophages.
What do my EBV results mean?
They may check IgG avidity test, the EA antibody test, or another test that detects the presence of DNA belonging to EBV [2]. A normal result can mean that you tested negative for antibodies and have never been infected. An abnormal result means you tested positive for antibodies and have a current or a past infection.
Which laboratory test diagnoses infectious mononucleosis?
The monospot (heterophile antibody test) is an older test that is commonly used to make the mono diagnosis. A positive monospot test accompanied by the symptoms of mono helps confirm a diagnosis of infectious mononucleosis.
What is the meaning of lab results?
In other words, lab test results are meant to answer a question or prove/disprove a hypothesis that was formulated prior to collection of samples. This is only possible if you have a well defined objective for collecting mold samples for lab testing.
What is EBV AB VCA, IgM?
The EBV AB VCA IgG is a test done to rule out present epstein bar virus infection or recent previous infection or past exposure to EBV. You see once the exposed to the virus the test may remain elevated for life.
What does abnormal lab value mean?
Abnormal lab values may indicate the need for ultrasounds or other medical imaging to determine the cause. Abnormal lab values may mean further testing needs to be done. A urinalysis is a common laboratory test done to help diagnose illness. Abnormal lab values may indicate thyroid problems.
