The Manual Blood Culture test uses conventional (non-automated) aerobic and anaerobic culture methods to detect microorganisms in a patient’s blood. Critical in diagnosing sepsis, septicemia, endocarditis, or chronic bacteremia, it helps pinpoint bloodstream infections. When positive, the culture is identified and tested for antibiotic susceptibility when appropriate to guide effective antimicrobial therapy.

The Lyme Disease DNA Qualitative Blood Test detects genetic material from Borrelia burgdorferi, the bacteria that cause Lyme disease. This test identifies active infection by analyzing bacterial DNA in the blood. Doctors use it to confirm Lyme disease in patients with symptoms such as fever, fatigue, or joint pain, particularly after tick exposure. It supports early diagnosis and guides treatment to prevent long-term complications.

The Lyme Disease IgG Antibody Immunoblot Test confirms exposure to Borrelia burgdorferi, the bacteria that cause Lyme disease. It detects IgG antibodies, which usually appear weeks after infection and remain present for months to years. Doctors use this test to confirm a positive screening result, evaluate late-stage Lyme symptoms, and support diagnosis in patients with joint pain, fatigue, or neurological complications from suspected Lyme disease.

The Heterophile Mono Screen, also called the Monospot Test, detects heterophile antibodies produced during infection with Epstein-Barr virus (EBV), the cause of infectious mononucleosis. Doctors order this test for patients with sore throat, fever, swollen lymph nodes, or fatigue. A positive result suggests mono, while negative results may require additional EBV testing. Results help confirm diagnosis and guide treatment for infectious mononucleosis.

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 Brucella IgG IgM Antibodies Test with Reflex to Agglutination evaluates immune response to Brucella bacteria, which cause brucellosis. It aids in detecting acute or chronic infection, assessing exposure risks, and clarifying unexplained symptoms such as fever, sweats, fatigue, and musculoskeletal pain. Reflexive agglutination testing enhances accuracy, supporting the diagnosis of zoonotic disease and systemic infection.

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 Lyme Disease Antibody Test with Reflex to Blot IgG IgM screens for antibodies to Borrelia burgdorferi, the bacteria that cause Lyme disease. If results are positive or equivocal, a Western blot IgG/IgM is reflexively performed for confirmation. Doctors order this test for patients with tick exposure, rash, joint pain, or neurological symptoms. Results help confirm infection, guide treatment decisions, and support early detection to prevent complications.

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) 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 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 Bartonella Species IgG IgM Antibodies with Reflex to Titer Test detects antibodies to Bartonella, the bacteria that cause cat scratch disease and other infections. IgM suggests recent infection, while IgG indicates past or ongoing exposure. If positive, titers confirm antibody levels. Doctors use this test to evaluate patients with fever, swollen lymph nodes, or suspected vector-borne illness, helping confirm diagnosis and guide treatment.

The Hepatitis B Core IgM Antibody Test is a qualitative test that detects IgM antibodies to the hepatitis B core antigen (anti-HBc IgM) and reports results as Reactive or Non-Reactive. A reactive result indicates a recent or acute hepatitis B infection, while a non-reactive result suggests no active infection. Doctors order this test to confirm acute hepatitis B in patients with symptoms such as jaundice, fatigue, fever, or abdominal pain and to guide treatment and monitoring.

The Clostridium difficile Toxin B Qualitative Test detects the presence of toxin B, a major virulence factor of C. difficile infection. This stool-based test helps identify active infection in patients with diarrhea, abdominal pain, or recent antibiotic use. Positive results support diagnosis of C. difficile–associated disease, which may cause colitis or severe gastrointestinal complications, aiding clinical evaluation and treatment decisions.

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 Lyme Disease IgG IgM Antibodies Immunoblot Test detects antibodies to Borrelia burgdorferi, the bacteria causing Lyme disease. IgM indicates recent infection, while IgG suggests past or ongoing infection. Doctors order this test to confirm exposure after ELISA screening or when symptoms such as rash, fatigue, joint pain, or neurological issues appear. Results provide critical insight for diagnosing and managing Lyme disease with greater accuracy.
