The Rabies Vaccine Response End Point Titer Test measures rabies virus–neutralizing antibodies to assess immune response after vaccination. By quantifying antibody levels, this test determines whether protective immunity has been achieved, guides decisions on booster doses, and monitors long-term vaccine effectiveness. It is especially valuable for individuals at occupational risk of rabies exposure.

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 Myocardial Antibody Screen with Reflex to Titer test is a specialized diagnostic blood test designed to detect the presence of autoantibodies targeting myocardial (heart muscle) tissue. Autoimmune responses against the heart can contribute to inflammation, damage, and dysfunction of cardiac tissue, leading to conditions such as myocarditis and cardiomyopathy. This test serves as an essential tool in identifying immune-mediated cardiac disorders by screening for myocardial antibodies and, if positive, determining the antibody titer level. The titer measurement helps assess the severity of the immune response and aids in monitoring disease progression or response to treatment.

The Endomysial IgA Antibody Screen with Reflex to Titer Test measures IgA antibodies linked to celiac disease and gluten sensitivity. It supports evaluation of chronic diarrhea, abdominal pain, weight loss, or nutrient deficiencies tied to autoimmune activity. Reflex to titer enhances diagnostic clarity, providing valuable information about intestinal damage, immune health, and systemic conditions.

The RPR Test with Reflex to Titer and Confirmatory Testing screens for syphilis by detecting non-treponemal antibodies. If reactive, results are automatically followed by a titer to measure antibody concentration and confirmatory treponemal testing for accuracy. Doctors use this test to diagnose active or past syphilis, monitor treatment, or screen at-risk patients. Results provide vital insight into infection status, disease stage, and overall sexual health.

The Hepatitis A & B Titer Test Panel is a comprehensive diagnostic tool designed to evaluate an individual's immunity status or infection presence for Hepatitis A and Hepatitis B viruses. This panel combines serological assays that measure specific antibodies and antigens associated with Hepatitis A and B, providing crucial insights for clinical diagnosis, vaccination verification, and the assessment of immune response post-vaccination or post-exposure.

The Diphtheria Titer Test measures antibody levels to evaluate immune protection against Corynebacterium diphtheriae, the bacterium that causes diphtheria. This test helps determine whether immunity is adequate following vaccination or exposure. By assessing diphtheria antibody titers, it provides insight into immune system response, vaccine effectiveness, and long-term protection against this serious infection.

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.

 The Hepatitis B Titer Test Panel is a diagnostic panel that comprises three essential tests designed to assess immunity, infection status, and antibody levels for the Hepatitis B virus (HBV). The panel includes the following tests: Hepatitis B Core Antibody Total, Hepatitis B Surface Antibody Quantitative, and Hepatitis B Surface Antigen with Reflex Confirmation.

The Student Titers Panel evaluates immunity to key infections often required for school or healthcare enrollment. It includes Hepatitis B Surface Antibody, Measles IgG, Mumps IgG, Rubella IgG, Varicella-Zoster Virus IgG, and QuantiFERON-TB Gold Plus for tuberculosis. Results confirm vaccination response or past exposure, helping students meet program requirements and ensure protection against preventable diseases.

The Measles Titer Test measures IgG antibody levels to determine immunity from prior measles infection or vaccination. A positive result indicates protective immunity, while a negative result suggests susceptibility. Doctors order this test to confirm immune status for school, healthcare, travel, or employment requirements. It is also used to verify vaccination response, ensuring individuals are protected against measles and reducing outbreak risk.

The Poliovirus 1 and 3 Titer Test measures neutralizing antibodies to poliovirus types 1 and 3 to evaluate immunity from vaccination or past infection. Doctors order this test to confirm protective immunity, assess response to polio vaccines, or check susceptibility in healthcare, laboratory, or travel settings. Results help determine if additional vaccination is needed and provide vital information for monitoring polio immunity and global disease prevention.
