Trimethylamine N-Oxide (TMAO), Serum
Labcorp
Not offered
This test measures the levels of TMAO in your blood, a substance linked to heart health.

Trimethylamine N-Oxide (TMAO), Whole Blood
Quest
Not offered
Trimethylamine N-oxide (TMAO) is a compound produced by gut bacteria from dietary nutrients such as choline and carnitine. Measuring TMAO levels can help assess cardiovascular disease risk, evaluate gut microbiome imbalance (dysbiosis), and monitor the effectiveness of TMAO-reducing interventions.

Trout (f204) IgE
Labcorp
Not offered
This test measures the immune system's response to trout, helping to identify potential allergies to this specific fish. By analyzing a small serum sample, healthcare providers can determine if an individual has an IgE-mediated allergy to trout, which is crucial for managing dietary restrictions and preventing allergic reactions.
Tryptase
Tryptase is an enzyme released primarily by mast cells during allergic reactions and inflammatory responses. It is commonly used to help diagnose mast cell activation disorders, including anaphylaxis and systemic mastocytosis.
- 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, Pregnancy
Labcorp
Not offered
This test measures the levels of Thyroid Stimulating Hormone (TSH) which are typically lower during pregnancy, especially in the first trimester. Recent studies have found that even slightly elevated TSH levels during pregnancy can lead to negative outcomes. Following this, the American Thyroid Association recommends using specific reference intervals for each trimester to ensure accurate assessment.
- Thyroid-Stimulating Hormone (TSH) A pituitary hormone that signals your thyroid to produce hormone. The primary screening test for both underactive and overactive thyroid conditions.
Tumor Necrosis Factor-Alpha
This test measures the level of tumor necrosis factor-alpha (TNF-a) in the blood. TNF-a levels may be elevated in sepsis, autoimmune diseases, various infectious diseases, and transplant rejection.
- Tumor Necrosis Factor-Alpha, Highly Sensitive A key inflammatory signaling protein (cytokine) involved in immune response and implicated in many chronic inflammatory and autoimmune conditions.

Tuna (f40) IgE
Labcorp
Not offered
This test measures the body's allergic response to tuna by checking for specific IgE antibodies in the serum. It's crucial for diagnosing tuna allergies and guiding dietary recommendations.
Turkey Feathers (e89) IgE
Labcorp
Not offered
This test measures an individual's allergic reaction to turkey feathers by quantifying the IgE response. It's a lab test used alongside other clinical information to help diagnose allergic conditions.
Turkey Meat (f284) IgE
Labcorp
Not offered
The Turkey Meat (f284) IgE test measures a person's IgE response to turkey meat, helping to identify potential food allergies. This test is performed in a lab and is used alongside other clinical information for a comprehensive diagnosis. While a positive result indicates sensitivity to turkey meat, it doesn't necessarily mean you'll experience allergic symptoms upon eating it. A thorough evaluation by a healthcare provider is essential for an accurate food allergy diagnosis.
Tyrophagus putrescentiae (d72) IgE
Labcorp
Not offered
This test checks for an allergic reaction to a specific type of mite known as Tyrophagus putrescentiae. It measures the level of IgE antibodies in the blood, which are higher if you're allergic to this mite. This test can help diagnose allergies and guide treatment plans.
Urea Nitrogen, 24-Hour Urine without Creatinine
Labcorp
Not offered
This quantitative urea nitrogen test, performed with a 24-hour urine specimen, may help estimate nitrogen balance and determine protein need in patients in critical conditions or receiving intravenous administration of nutrition.
Uric Acid
This test measures uric acid. It can help diagnose gout, renal failure, and a variety of other conditions.
- 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.
