Anti-Tau (IgG + IgA) measures the immune system’s response to tau protein, a structural protein in neurons that helps stabilize microtubules—the internal “tracks” used for nutrient delivery, cell stability, and healthy nerve communication.

When tau proteins become damaged or misfolded, they can form tau tangles, which are associated with:

• Neuroinflammation
• Neuronal instability and injury
• Impaired cellular transport and energy function
• Cognitive decline in neurodegenerative conditions

This test does not diagnose Alzheimer's disease, frontotemporal dementia, or other tau-related disorders. Rather, it helps identify whether the immune system is reacting to tau proteins, which can signal neuroimmune activation, neuronal stress, or early protective immune surveillance.

A mild elevation in Anti-Tau (IgG + IgA) suggests early immune awareness of tau proteins, which may reflect subtle neuroinflammation or neuronal stress.

This does not diagnose Alzheimer's or other neurodegenerative diseases.

What it may suggest

• Early-phase immune signaling around neuronal proteins
• Mild oxidative or metabolic stress affecting the brain
• Possible blood-brain barrier or tau turnover shifts

Supportive steps

• Prioritize sleep and stress regulation
• Anti-inflammatory, polyphenol-rich diet
• Regular aerobic + strength exercise
• Maintain blood sugar balance
• Support gut-brain health

Monitoring and preventive care are reasonable, especially if symptoms or strong family history are present.

Thyroglobulin antibodies are antibodies that recognize and bind to thyroglobulin, interfering with its function. Thyroglobulin is critical for thyroid hormone production, so thyroglobulin antibodies usually indicate thyroid disease.

The marker "Anti-Thyroglobulin Antibody" is serving as an essential tool in assessing autoimmune thyroid disorders, such as Hashimoto's thyroiditis and Graves' disease.

Thyroglobulin itself is a protein produced by the thyroid gland, playing a pivotal role in the synthesis of thyroid hormones. However, in certain autoimmune conditions, the body's immune system mistakenly identifies thyroglobulin as a foreign substance, leading to the production of anti-thyroglobulin antibodies. The presence and concentration of these antibodies can be indicative of an underlying autoimmune thyroid condition.

What if results are borderline elevated?

When Anti-Thyroglobulin Antibody levels are borderline elevated, it suggests a potential, mild autoimmune reaction against the thyroid gland, but interpretation depends on the overall clinical picture. Healthcare providers typically recommend a combination of symptom evaluation, further thyroid function tests, and periodic monitoring of antibody levels to detect any changes over time. The presence of risk factors such as a family history of autoimmune diseases and the patient's symptoms are also considered in assessing the likelihood of developing a thyroid disorder. In some cases, lifestyle modifications or early medical interventions may be advised to manage symptoms and support thyroid health, highlighting the importance of a proactive and informed approach to borderline results.

Associated Disease: Hashimoto’s Thyroiditis & Graves’ Disease

Sensitivity: 60-85%

Interpretation: Anti-thyroglobulin antibodies are found in 60-85% of patients with Hashimoto’s thyroiditis and 30-80% of patients with Graves’ disease.

Anti-Tissue Transglutaminase IgA (tTG IgA) is the primary and most reliable test for detecting celiac disease, measuring IgA antibodies produced in response to gluten. Elevated levels strongly suggest celiac disease, as they indicate immune-driven damage to the intestinal lining. However, in individuals with IgA deficiency, results may appear normal, requiring alternative tests like tTG IgG. If tTG IgA is elevated, further evaluation, such as an intestinal biopsy, is often recommended to confirm the diagnosis and guide treatment with a gluten-free diet.

Anti-Tissue Transglutaminase IgG (tTG IgG) is a key marker used in celiac disease testing, particularly for individuals with IgA deficiency, where standard tTG IgA results may be unreliable. Elevated tTG IgG levels suggest the immune system is reacting to gluten, which can indicate celiac disease or, in some cases, non-celiac gluten sensitivity. However, tTG IgG can occasionally be elevated due to other conditions, such as liver disease or autoimmune disorders. If your tTG IgG is high, it’s important to consult with your healthcare provider, who may recommend additional tests, like a biopsy or further antibody screening, to confirm celiac disease and guide the next steps for managing gluten-related symptoms.

The Anti-Titin (IgG + IgA) biomarker, measured in Vibrant Wellness' Neural Zoomer Plus panel, assesses immune reactivity to titin, a giant protein critical for muscle elasticity and contraction. This test helps identify autoimmune responses targeting neuromuscular tissues, which may underlie conditions like myasthenia gravis and thymoma-associated syndromes.

What It Measures

The test detects IgG and IgA antibodies against titin, a structural protein in skeletal and cardiac muscle. Titin stabilizes sarcomeres during muscle contraction, and autoantibodies against it are often linked to neuromuscular junction dysfunction.

Clinical Relevance

Anti-Titin antibodies are associated with:

• Myasthenia Gravis (MG):

  • Found in approximately 30% of generalized MG cases, particularly in patients with thymoma (a tumor of the thymus).

  • Associated with severe disease phenotypes and poorer response to acetylcholinesterase inhibitors.

• Thymoma Screening:

  • The presence of Anti-Titin antibodies may prompt imaging (e.g., chest CT) to rule out thymic tumors.

• Late-Onset MG:

  • More common in patients over 50, often without thymoma, but with higher rates of muscle-specific kinase (MuSK) antibodies.

Anti-TPO antibodies (Anti-Thyroid Peroxidase antibodies) are autoantibodies directed against thyroid peroxidase, an enzyme crucial for the production of thyroid hormones. These antibodies are a key marker in autoimmune thyroid diseases, particularly Hashimoto's thyroiditis and, to a lesser extent, Graves' disease. In Hashimoto's thyroiditis, which is the most common cause of hypothyroidism, the presence of Anti-TPO antibodies signifies an immune system attack on the thyroid gland, leading to inflammation, damage, and eventually reduced thyroid function. Patients with elevated levels of Anti-TPO antibodies are at an increased risk of developing hypothyroidism, even if their thyroid function is normal at the time of testing. In Graves' disease, which is characterized by hyperthyroidism, Anti-TPO antibodies are less commonly present but can coexist with other types of thyroid autoantibodies.

Anti-Tubulin antibodies are immune proteins that target tubulin, a structural protein inside nerve cells that helps maintain neuronal shape, stability, and communication. Elevated titers may indicate immune activity directed at the nervous system, a pattern sometimes seen in neuro-immune conditions such as PANS, PANDAS, Sydenham chorea, and other autoimmune processes affecting the brain.

The Anti-U1 RNP (Ribonucleoprotein) Antibody test is a specific diagnostic tool used in the evaluation of connective tissue diseases. This test detects antibodies against the U1 RNP, a component of a small nuclear ribonucleoprotein complex involved in RNA processing. The presence of anti-U1 RNP antibodies is particularly significant in the diagnosis of mixed connective tissue disease (MCTD), a disorder that exhibits features of several connective tissue diseases like systemic lupus erythematosus, scleroderma, and polymyositis.

Voltage-gated calcium channels (VGCCs) are a group of voltage-gated ion channels found in the membrane of excitable cells such as muscle, glial cells, and neurons. They are key transducers of membrane potential changes into intracellular Ca2+ transients that initiate many physiological events. In neurons, voltage-gated Ca2+ channels initiate synaptic transmission. Anti-voltage-gated calcium channel autoantibodies are responsible for Lambert-Eaton myasthenic syndrome (LEMS), a rare autoimmune disorder of the neuromuscular junction.

The Anti-Voltage Gated Calcium Channels (VGCC) IgM biomarker is a specialized test used to detect antibodies against the voltage-gated calcium channels in the nervous system. These calcium channels play a crucial role in the function of neurons, helping to regulate the flow of calcium ions in and out of nerve cells, which is essential for the proper transmission of electrical signals in the brain and throughout the nervous system.

What It Measures: This test specifically measures IgM antibodies directed against these voltage-gated calcium channels. IgM is a type of antibody that typically appears early in immune responses. The presence of Anti-VGCC IgM antibodies can suggest an autoimmune response, where the immune system mistakenly targets these calcium channels, potentially disrupting normal nerve cell function.

Clinical Relevance: The presence of Anti-VGCC IgM antibodies has been linked to several neurological conditions, most notably paraneoplastic neurologic syndromes (PNS). In PNS, the immune system targets components of the nervous system in response to an underlying malignancy. These conditions may lead to symptoms such as muscle weakness, vision disturbances, memory issues, or even severe conditions like Lambert-Eaton Myasthenic Syndrome (LEMS), a disorder that impairs communication between nerves and muscles.
