• Trimethylamine N-OxideTMAO Trimethylamine N-oxide, a compound produced by gut bacteria from certain foods (like red meat and eggs). Elevated levels are studied as a marker of cardiovascular risk.
• Triple Phosphate Crystals Detects triple phosphate (struvite) crystals in urine, which usually form in alkaline urine and can be linked to certain urinary infections.
• Troponin T (Highly Sensitive) A protein released specifically from damaged heart muscle. The primary marker used to detect a heart attack.
• Trout (f204) IgE Measures IgE antibodies to trout to check for allergic sensitization to this freshwater fish, interpreted alongside any symptoms after eating it.
• Tryptase An enzyme released by mast cells. Elevated levels can indicate a severe allergic reaction (anaphylaxis) or, if persistently high, a mast cell disorder.
• TSH Receptor Binding AntibodyTRAb Measures antibodies that bind to the TSH receptor on the thyroid, used mainly to look into Graves' disease and some causes of overactive thyroid.
• Tumor Necrosis Factor-Alpha, Highly SensitiveTNF-alpha A key inflammatory signaling protein (cytokine) involved in immune response and implicated in many chronic inflammatory and autoimmune conditions.
• Tuna (f40) IgE Measures IgE antibodies to tuna to check for allergic sensitization to this fish, interpreted alongside any symptoms after eating it.
• Tuna (f40) IgG4 Measures IgG4 antibodies to tuna, which mainly reflect how often you eat it; their link to food-related symptoms is debated.
• Turkey Feathers (e89) IgE Measures IgE antibodies to turkey feathers to check for allergic sensitization, mainly relevant to poultry workers and people who keep birds.
• Turkey IgG4 Measures IgG4 antibodies to turkey meat, which mainly reflect how often you eat it; their link to food-related symptoms is debated.
• Turkey Meat (f284) IgE Measures IgE antibodies to turkey meat to check for allergic sensitization to this poultry, interpreted alongside any symptoms after eating it.
• Tyrophagus putrescentiae (d72) IgE Measures IgE antibodies to Tyrophagus putrescentiae, a storage mite found in stored foods and damp homes, to check for allergic sensitization.
• UGT1A1 Genotype Identifies inherited variants in the UGT1A1 gene, which affect how your body processes bilirubin and some medicines; it is a lifelong genetic result.
• UGT1A1 Phenotype The predicted UGT1A1 enzyme activity, such as normal, intermediate or poor metabolizer, worked out from your UGT1A1 genotype.
• Unsaturated Iron Binding CapacityUIBC Unsaturated Iron-Binding Capacity — reflects how much additional iron your blood's transferrin could still carry, used with iron and TIBC to assess iron status.
• Urea Nitrogen, 24 Hr Measures how much urea nitrogen you pass in urine over 24 hours, giving a look at protein intake, protein breakdown and nitrogen balance.
• Urea Nitrogen, Random Measures urea nitrogen in a single urine sample, a waste product of protein breakdown, to help look at protein intake and kidney handling.
• Uric Acid A waste product from the breakdown of purines. Elevated levels are linked to gout and kidney stones, and can also reflect metabolic health.
• Uric Acid, 24 Hour Measures the total uric acid you pass in urine over 24 hours, used to look into kidney stones and how your body handles uric acid.
