The Rickettsia Antibody Test Panel with Reflex to Titers detects IgG and IgM antibodies to Rickettsia species associated with spotted fever and typhus group infections. This test helps identify recent or past Rickettsial exposure, aiding in the diagnosis of diseases such as Rocky Mountain spotted fever and murine typhus, with reflex titers providing confirmation and infection stage assessment.
The Babesia microti IgG IgM Antibodies Test detects antibodies to the parasite that causes babesiosis, a tick-borne infection affecting red blood cells. IgM indicates recent or active infection, while IgG suggests past or ongoing exposure. Doctors use this test to diagnose babesiosis in patients with fever, chills, anemia, or fatigue, and to differentiate it from Lyme disease or other tick-borne illnesses for accurate treatment.
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 Ehrlichia chaffeensis IgG IgM Antibodies Test detects immune response to the bacterium responsible for human monocytic ehrlichiosis (HME). Measuring both IgM and IgG provides information on recent or past infection, helping identify acute illness or prior exposure. This blood test supports evaluation of tick-borne disease in patients with symptoms such as fever, fatigue, or cytopenias, guiding clinical assessment and patient management.
The Epstein-Barr Virus (EBV) Viral Capsid Antigen (VCA) IgA Antibody Test detects IgA antibodies that may indicate recent or reactivated EBV infection. Elevated IgA levels are often associated with nasopharyngeal carcinoma and other EBV-related conditions. Doctors order this test for patients with persistent sore throat, swollen lymph nodes, or suspected EBV reactivation. Results provide valuable insight for diagnosis, cancer risk assessment, and ongoing monitoring.
The Sensory-Motor Neuropathy Antibody Panel (Ganglioside) detects IgG and IgM autoantibodies against gangliosides GM1, Asialo-GM1, GD1a, GD1b, and GQ1b via immunoassay. High GM1 titers are characteristic of multifocal motor neuropathy; other ganglioside antibodies appear in sensorimotor neuropathies. The test uses serum (overnight fasting preferred) and aids evaluation of immune-mediated neuropathy, motor dysfunction, lower motor neuron disease.
The Striated Muscle Antibody Test with Reflex to Titer detects antibodies targeting striated muscle, often linked to autoimmune conditions and paraneoplastic syndromes. Elevated levels may indicate myasthenia gravis, thymoma, or other neuromuscular disorders. Reflex titers help assess antibody concentration, supporting diagnosis, monitoring disease activity, and guiding evaluation of immune-mediated muscle weakness.
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 ANCA Screen with Reflex to ANCA Titer detects antineutrophil cytoplasmic antibodies, often linked to autoimmune vasculitis such as granulomatosis with polyangiitis and microscopic polyangiitis. If the screen is positive, a titer is performed to measure antibody levels for greater diagnostic accuracy. Doctors use this test to evaluate unexplained inflammation, kidney or lung issues, and guide treatment decisions in autoimmune and systemic vasculitis care.
The Lymphogranuloma Venereum (LGV) Differentiation Antibody Panel uses micro-immunofluorescence (MIF) to measure IgG, IgA, and IgM antibodies to Chlamydia trachomatis (LGV L1 and non-LGV D–K) and related Chlamydiaspecies (C. pneumoniae and C. psittaci). It helps differentiate antibody patterns consistent with LGV versus other chlamydial exposures when cross-reactivity may complicate interpretation.
The Myelin IgG Antibody Test detects antibodies targeting myelin, the protective sheath around nerves. Elevated levels may indicate autoimmune demyelinating disorders such as multiple sclerosis, neuromyelitis optica, or related inflammatory neuropathies. This test supports diagnosis, evaluation of neurological symptoms, and differentiation of demyelinating diseases that affect the central nervous system.
The Cardiolipin IgM Antibody Test measures IgM antibodies linked to antiphospholipid syndrome and autoimmune disorders. It helps evaluate unexplained blood clots, recurrent miscarriages, or abnormal clotting events. By detecting immune system activity against phospholipids, this test supports the assessment of vascular health, autoimmune activity, and risks related to thrombosis or systemic lupus erythematosus.
Evaluates antibodies linked to myasthenia gravis, including acetylcholine receptor binding antibodies and striated muscle antibodies. This panel helps assess autoimmune activity affecting neuromuscular function and supports evaluation of symptoms such as muscle weakness, fatigue, drooping eyelids, and difficulty swallowing.
The Islet Cell Antibody Screen with Reflex to Titer detects autoantibodies directed against pancreatic islet cells, which play a key role in insulin production. The presence of islet cell antibodies suggests autoimmune destruction of beta cells, often associated with type 1 diabetes or latent autoimmune diabetes in adults (LADA). Reflex testing to titer quantifies antibody concentration for diagnostic confirmation.
