Taurine differs from other amino acids because a sulfur group replaces the carboxyl group of what would be the nonessential amino acid, β-alanine. It takes part in biochemical reactions and is not fully incorporated into proteins.

In most tissues, it remains a free amino acid. Taurine’s highest concentration is in muscle, platelets, and the central nervous system.

Taurine is mainly obtained via dietary sources (dairy, shellfish, turkey, energy drinks), but can also come from sulfur amino acid metabolism (methionine and cysteine).

It has been proposed that taurine acts as an antioxidant, intracellular osmolyte, membrane stabilizer, and a neurotransmitter.

Taurine important for proper heart function, healthy sleep and promoting calmness.

Taurine is an amino sulfonic acid, but it is often referred to as an amino acid, a chemical that is a required building block of protein. Taurine is found in large amounts in the brain, retina, heart, and blood cells called platelets. 

Taurine is a sulfur-containing amino acid required for bile formation.

The TB1-NIL biomarker is integral to the QuantiFERON-TB Gold Plus (QFT-Plus) assay, a diagnostic tool used to detect Mycobacterium tuberculosis infection. In this context, 'NIL' refers to the baseline interferon-gamma (IFN-γ) level measured without antigen stimulation, serving as a negative control to account for non-specific background activity. The TB1 tube contains antigens that primarily stimulate CD4+ T-cell responses. By subtracting the NIL value from the TB1-stimulated IFN-γ level (TB1-NIL), clinicians can assess the specific immune response to TB antigens. A TB1-NIL value of 0.35 IU/mL or higher typically indicates a positive result, suggesting a TB infection. This method enhances the accuracy of TB diagnosis by distinguishing specific immune responses from background noise.

The TB2-NIL biomarker is a critical component of the QuantiFERON-TB Gold Plus (QFT-Plus) assay, which is used to detect Mycobacterium tuberculosis infection. In this context, 'NIL' refers to the baseline interferon-gamma (IFN-γ) level measured without antigen stimulation, serving as a negative control to account for non-specific background activity. The TB2 tube contains antigens designed to stimulate both CD4+ and CD8+ T-cell responses. By subtracting the NIL value from the TB2-stimulated IFN-γ level (TB2-NIL), clinicians can assess the specific immune response to TB antigens. A TB2-NIL value of 0.35 IU/mL or higher typically indicates a positive result, suggesting a TB infection. This method enhances the accuracy of TB diagnosis by distinguishing specific immune responses from background noise.

The presence of antibodies to Teff is an indication of food immune reactivity. The offending food and its known cross-reactive foods should be eliminated from the diet. Little work has been published on this food product. Due to the prevalence of its consumption by, and low incidence of diabetes, in Ethiopians, it can be postulated that Teff may be a healthy alternative grain for patients needing to consume a
low-glycemic diet. Teff has also been considered to be safe for Celiac patients, as it does not contain alpha-gliadin and has no cross-reactivity to the alpha-gliadin of wheat. If a recently diagnosed non-celiac gluten-sensitive patient exhibits high levels of antibodies to Teff, it may be due to the late introduction of Teff into the diet.

Tellurium (Urine) on Vibrant’s Total Tox-Burden reflects your recent body burden of this rare metalloid and is reported creatinine-corrected; a value ≤ 0.89 µg/g is typical for the reference population, while results above this cut-off suggest higher-than-expected recent exposure. Common sources are occupational or environmental—e.g., copper/lead refining by-products, electronics/thermoelectric materials, CdTe solar manufacturing, and telluride-containing alloys. Higher exposures may cause nonspecific symptoms (fatigue, nausea, metallic taste) and the classic garlic-like odor from dimethyl telluride excretion. Because urine reflects elimination, a single value can’t pinpoint timing/duration, and hydration status can influence results; don’t compare non-provoked results with provoked (chelator) tests. If elevated, focus on exposure reduction (controls/PPE and hygiene), avoid self-directed chelation, stay well hydrated, and consider clinician-guided retesting after changes.
