The Epstein-Barr Virus Antibody (EBV) Panel detects antibodies to EBV, including VCA IgM, VCA IgG, and EBNA IgG, to determine current, recent, or past infection. EBV causes infectious mononucleosis and has links to chronic fatigue and certain cancers. Doctors order this test for patients with fever, sore throat, swollen lymph nodes, or fatigue. Results help identify stage of infection, confirm diagnosis, and guide clinical management of EBV-related illness.

The West Nile Virus IgG IgM Antibodies Test measures immune response to West Nile virus, distinguishing recent from prior infection. IgM levels indicate active or recent illness, while IgG reflects past exposure or long-term immunity. This test aids in evaluating unexplained fever, flu-like symptoms, or neurological complications, supporting assessment of vector-borne viral infection and systemic health.

The Epstein-Barr Virus (EBV) Nuclear Antigen (EBNA) IgG Antibody Test detects IgG antibodies that usually appear after acute infection, confirming past exposure or infection recovery. Doctors order this test alongside VCA and EA antibodies to determine the stage of EBV infection. Results help distinguish recent versus past EBV, guide diagnosis of mononucleosis, and support evaluation of chronic fatigue or EBV-related health conditions.

The Varicella Zoster Virus IgG IgM Antibodies Panel is used to assess exposure to the varicella-zoster virus, which causes both chickenpox and shingles. By evaluating the presence and levels of specific antibodies, this panel aids in diagnosing current infections, determining immunity, and guiding vaccination decisions.

The Epstein-Barr Virus (EBV) Comprehensive Panel measures VCA IgM, VCA IgG, EBNA IgG, and Early Antigen D IgG antibodies to evaluate stage of EBV infection. This virus causes mononucleosis and has links to chronic fatigue, autoimmune conditions, and certain cancers. Doctors order this test for patients with fever, sore throat, lymph node swelling, or prolonged fatigue. Results help distinguish acute, past, or reactivated EBV infection and guide clinical care.

The Coxsackie B Virus Antibodies test is a diagnostic blood test used to detect antibodies produced by the immune system in response to a Coxsackie B virus infection. Coxsackie B viruses belong to the enterovirus family and are associated with a range of illnesses, from mild flu-like symptoms to more severe conditions such as viral myocarditis and meningitis. This test measures the presence of specific antibodies against Coxsackie B viruses, helping to confirm recent or past infections and assess the immune response to the virus. The test is particularly useful in identifying cases where Coxsackie B virus may be the underlying cause of unexplained cardiac, neurological, or systemic symptoms.

The Herpes Simplex Virus 1 IgG Type-Specific Antibody HerpeSelect® Test detects IgG antibodies to HSV-1, the virus commonly associated with oral herpes. A positive result indicates past exposure, as IgG develops weeks after infection and remains for life. Doctors use this test to confirm HSV-1 infection, evaluate unexplained sores, or guide sexual health management. Results provide essential insight into infection history, immune response, and long-term HSV-1 status.

The Epstein-Barr Virus (EBV) Viral Capsid Antigen (VCA) IgG Antibody Test detects IgG antibodies that appear after EBV infection and usually persist for life. Positive results indicate past exposure or infection with EBV, the virus that causes mononucleosis. Doctors order this test with VCA IgM and EBNA IgG to determine infection stage. Results help confirm prior EBV exposure, support diagnosis, and guide evaluation of EBV-related conditions.

The Varicella IgM Antibody Test measures IgM antibodies produced in response to varicella-zoster virus, helping identify current or recent chickenpox infection. It aids in differentiating acute illness from prior exposure or immunity. This test supports evaluation of symptoms such as rash, fever, or fatigue, and provides valuable information about immune activity and viral health risks.

The Epstein-Barr Virus (EBV) Viral Capsid Antigen (VCA) IgM Antibody Test detects IgM antibodies, which appear early during EBV infection. A positive result usually indicates recent or acute infection, including mononucleosis. Doctors order this test for patients with fever, sore throat, fatigue, or swollen lymph nodes. Results help confirm acute EBV infection, distinguish it from past exposure, and support accurate diagnosis and treatment decisions.

The Varicella Titer Test is a blood test that measures antibodies to the varicella-zoster virus (VZV), which causes chickenpox and shingles. A positive result indicates past infection, while a negative suggests no exposure. This test is not considered reliable for confirming immunity from vaccination. Doctors use it to evaluate history of natural infection, meet school or work requirements, and provide documentation of varicella exposure status.

The Epstein-Barr Virus (EBV) Early Antigen D IgG Antibody Test detects IgG antibodies to EBV’s early antigen, helping identify recent or reactivated infection. Elevated levels may indicate acute mononucleosis, viral reactivation, or chronic EBV. Doctors order this test when patients present with fatigue, fever, sore throat, or swollen lymph nodes. Results provide key insight into EBV activity, supporting diagnosis, monitoring, and treatment decisions.
