Results help identify stage of infection, confirm diagnosis, and guide clinical management of EBV-related illness.

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 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 Hepatitis A IgM Antibody Test is a qualitative blood test that detects IgM antibodies to the hepatitis A virus (HAV) and reports results as Reactive or Non-Reactive. A reactive result usually indicates a recent or current hepatitis A infection, while a non-reactive result means no active infection. Doctors use this test to confirm acute hepatitis A in patients with symptoms like jaundice, nausea, fatigue, or abdominal pain and to guide timely treatment and prevention.

The Immunoglobulin G (IgG) Test measures IgG antibody levels in blood to assess immune system function and long-term response to infections. Low IgG may indicate immune deficiencies or recurrent infections, while high levels may signal chronic inflammation, autoimmune disease, or certain infections. Doctors use this test to evaluate unexplained illness, monitor immune disorders, or assess overall immunity. Results provide vital insight into immune health and disease management.

The Hepatitis C Antibody Test with Reflex to RNA Quantitative PCR is a two-step test. The initial qualitative antibody screen detects past exposure to HCV and reports results as Reactive or Non-Reactive. If reactive, reflex PCR measures viral RNA to confirm active infection and determine viral load. Doctors use this test to diagnose hepatitis C, evaluate liver health, and guide treatment decisions, providing key information for accurate diagnosis and disease management.

The Hepatitis C Viral RNA Quantitative Test measures the amount of hepatitis C virus (HCV) RNA in blood to determine viral load. This test confirms active infection, evaluates disease severity, and monitors response to antiviral therapy. High viral load indicates significant viral replication, while lower or undetectable levels suggest effective treatment or controlled infection. Doctors use this test to guide therapy, track progress, and manage long-term liver health.

The Lactate Dehydrogenase (LDH) Test measures LDH enzyme levels in blood to assess tissue damage and overall health. Elevated LDH may indicate conditions such as liver disease, heart attack, anemia, infections, or certain cancers, while low levels are uncommon. Doctors use this test to help diagnose disease, monitor treatment effectiveness, and track cell damage. It provides valuable insight into metabolic activity and organ function.

The Neopterin Serum Test measures levels of neopterin, a marker released by activated macrophages in response to interferon-gamma. Elevated concentrations reflect immune system activation and may indicate viral infections, autoimmune disease, cancer, or transplant rejection risk. This test helps clinicians assess cellular immune response, track inflammatory activity, and evaluate disease progression or treatment monitoring.

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.

The Lyme Disease Antibody Test with Reflex to Blot IgG IgM screens for antibodies to Borrelia burgdorferi, the bacteria that cause Lyme disease.
