All Immunity and Titer Tests

The Rheumatoid Factor (RF) Test measures RF antibodies in blood to help diagnose rheumatoid arthritis and other autoimmune conditions. High RF levels may indicate rheumatoid arthritis, Sjögren’s syndrome, or other connective tissue diseases, though they can also appear in some infections. Doctors order this test to investigate joint pain, stiffness, or swelling. Results provide important insight into autoimmune activity, joint health, and inflammatory disease management.

Specimen Type: Serum

The Rheumatoid Factor IgA IgG IgM Antibodies Test measures multiple rheumatoid factor classes to aid in diagnosing rheumatoid arthritis and related autoimmune diseases. Elevated levels may suggest joint inflammation, Sjögren’s syndrome, lupus, or chronic infections. Doctors use this comprehensive test to confirm autoimmune involvement, investigate persistent pain or stiffness, and guide treatment planning by assessing disease activity across antibody types.

The Rheumatoid Factor IgA Antibody Test measures IgA-class rheumatoid factor, an autoantibody linked to rheumatoid arthritis and other autoimmune diseases. Elevated levels may indicate joint inflammation, Sjögren’s syndrome, or chronic infections. Doctors use this blood test alongside other markers to confirm diagnosis, assess disease activity, and guide treatment decisions for patients with suspected autoimmune or inflammatory disorders.

Specimen Type: Serum

The Rheumatoid Factor IgG Antibody Test measures IgG-class rheumatoid factor, an autoantibody often linked to rheumatoid arthritis and autoimmune diseases. Elevated levels may indicate joint inflammation, Sjögren’s syndrome, or chronic infection. Doctors use this test with other markers to confirm diagnosis, assess autoimmune activity, and guide treatment for patients with persistent joint pain, swelling, or suspected inflammatory disorders.

Specimen Type: Serum

The RPR (Monitor) with Reflex to Titer Test screens for syphilis by detecting antibodies to Treponema pallidum. If positive, a reflex titer determines antibody concentration to assess disease activity and treatment response. Doctors order this test to diagnose syphilis, monitor therapy, or check reinfection. Results provide essential information for managing active infection, confirming treatment success, and guiding follow-up care.

The Rubella IgG IgM Antibodies Test measures antibodies to the rubella virus, helping evaluate immunity or recent infection. IgM indicates an active or recent infection, while IgG confirms past infection or vaccination. Doctors use this test to assess immune status in women of childbearing age, screen during pregnancy, or confirm suspected rubella exposure, as infection can cause serious complications for unborn babies.

Specimen Type: Serum

The Rubella Titer Test measures IgG antibodies to determine immunity to rubella (German measles). A positive result indicates protection from prior infection or vaccination, while a negative result suggests susceptibility. Doctors order this test for women planning pregnancy, healthcare workers, students, or travelers. It helps confirm immune status, guide vaccination needs, and protect against congenital rubella syndrome and outbreak risks.

Specimen Type: Serum

The Selenium Micronutrient Blood Test measures selenium levels in the blood to assess nutritional status and detect deficiencies or excess. Selenium is a powerful antioxidant that supports thyroid function, immune defense, and protection against oxidative stress. This test helps identify dietary insufficiency, malabsorption, or toxicity, supporting diagnosis and management of overall health and wellness.

Patient must be 18 years of age or older.

Specimen Type: Blood

The Selenium Test measures selenium levels in blood to evaluate nutritional status and overall health. Selenium is essential for thyroid function, antioxidant defense, and immune support. Low levels may cause fatigue, muscle weakness, thyroid problems, or impaired immunity, while high levels may indicate toxicity. Doctors use this test to monitor nutrition, supplementation, or suspected deficiency. Results provide key insight into metabolic health and antioxidant balance.

Specimen Type: Serum

The Syphilis (RPR + FTA-ABS) panel is a diagnostic tool used to detect and confirm the presence of syphilis, a sexually transmitted infection (STI) caused by the bacterium Treponema pallidum. This panel combines two tests: the RPR (Rapid Plasma Reagin) Screen with Reflex to Titer, and the FTA-ABS (Fluorescent Treponemal Antibody Absorption) test, offering both initial screening and confirmatory diagnosis capabilities.

Specimen Type: Serum

The Syphilis FTA-ABS Test (Fluorescent Treponemal Antibody Absorption) detects antibodies specific to Treponema pallidum, the bacteria that cause syphilis. Doctors use this confirmatory test after a positive screening to verify infection, even in late or latent stages. Results help distinguish syphilis from false positives, guiding diagnosis, treatment, and follow-up. This test is essential for accurate detection and long-term monitoring of syphilis.

Specimen Type: Serum

The Syphilis RPR Test screens for syphilis by detecting nonspecific antibodies produced in response to Treponema pallidum. If positive, a reflex titer is performed to measure antibody levels and monitor disease activity. Doctors use this blood test to confirm infection, determine stage, and track treatment response. It is widely used for STD screening, prenatal care, and early detection to prevent complications and transmission.

The Tetanus and Diphtheria Titer Test measures antibody levels to determine immunity from prior vaccination or exposure. Adequate titers indicate protective immunity, while low levels may suggest the need for a booster. Doctors order this test for healthcare workers, students, travelers, or those with uncertain vaccination history. It provides essential information for maintaining protection against these serious bacterial infections.

The Tetanus Antitoxoid Test evaluates antibody levels to tetanus toxin, offering information about immune defense and vaccination status. Adequate levels indicate protection, while low results may suggest reduced immunity. This test aids in assessing immune response, monitoring vaccine effectiveness, and identifying systemic conditions that influence antibody production and immune balance.

Specimen Type: Serum

The Trimethylamine N-Oxide (TMAO) Test measures TMAO levels in blood to assess cardiovascular and metabolic risk. TMAO is produced when gut bacteria metabolize nutrients like choline, carnitine, and betaine from foods such as red meat and eggs. Elevated levels are linked to heart disease, stroke, kidney dysfunction, and metabolic disorders. Doctors order this test to evaluate cardiovascular risk and guide lifestyle, diet, or treatment strategies.

Specimen Type: Serum

Specimen Type: Serum

The Toxoplasma IgG Antibody Test detects IgG antibodies to Toxoplasma gondii, the parasite that causes toxoplasmosis. A positive result indicates past infection or immunity, while rising levels may suggest recent exposure. Doctors use this blood test to evaluate immune status in pregnant women, immunocompromised patients, or those at risk for complications. Results help guide diagnosis, monitor infection history, and inform patient care planning.

Specimen Type: Serum

The QuantiFERON®-TB Gold Plus (QFT-Plus) Test is a modern blood test that detects tuberculosis infection, including latent and active TB. Unlike the traditional skin test, it does not require a return visit and provides highly specific results by measuring interferon-gamma release in response to TB antigens. Physicians use this test to screen high-risk individuals, confirm TB exposure, and guide timely treatment decisions for better patient outcomes.

Specimen Type: Blood

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.

Specimen Type: Serum
