Description: Thyroid autoantibodies are antibodies that develop when an immune system mistakenly targets components of your thyroid gland or thyroid proteins, leading to inflammation of the thyroid (thyroiditis), tissue damage, and/or disruption of thyroid function. Lab tests detect presence and measure the quantity of specific thyroid autoantibodies in the blood.
The thyroid is a small, butterfly-shaped gland that lies flat against the windpipe in your throat. The primary hormones that it produces, thyroxine (T4) and triiodothyronine (T3), are vital in regulating the rate at which the body uses energy (metabolism). The body uses a system in which thyroid stimulating hormone (TSH) stimulates the thyroid to produce T4 and T3. This system helps maintain a stable amount of the thyroid hormones in the blood. When thyroid antibodies interfere with this process, it can lead to chronic conditions and autoimmune disorders associated with hypothyroidism or hyperthyroidism.
Includes:TGAb - A thyroglobulin antibodies (TgAb) test is used to check blood levels of antibodies the body has made against the compound thyroglobulin. Thyroglobulin is a protein produced and used by the thyroid gland (the small, butterfly-shaped gland in the neck) to make the hormones triiodothyronine (T3) and thyroxine (T4), both of which help control metabolism and growth.
TPO - A thyroid peroxidase (TPO) antibodies test checks the levels of antibodies made against the compound thyroid peroxidase (TPO) in the bloodstream. Thyroid peroxidase is an enzyme produced by the thyroid gland. The thyroid is a small, butterfly-shaped gland in the neck that uses iodine, with the help of the enzyme TPO, to create the hormones triiodothyronine (T3) and thyroxine (T4), both of which help control metabolism and growth. Antibodies are proteins made by the immune system, usually to fight bacteria, viruses, and toxins that enter or contact the body.

Free T’s Plus TSH

Only $59

 
DLS Regular Price: $69
Fasting Required: No
Specimen: Blood
Lab: Quest Diagnostics
Results: 2-3 Business Days
Note: Result turnaround times are an estimate and are not guaranteed. Our reference lab may need additional time due to weather, holidays, confirmation/repeat testing, or equipment maintenance.
Tests Included:
Free T3: This test is used to evaluate thyroid function. It is primarily used to diagnose hyperthyroidism. It is also used to assess abnormal binding protein disorders and to monitor thyroid replacement and suppressive therapy.
Free T4: This test is used to evaluate thyroid function in individuals who may have protein abnormalities that could affect total T4 levels. It is used to evaluate thyroid function and monitor replacement and suppressive therapy.
TSH: The best way to initially test thyroid function is to measure the TSH level in a blood sample. A high TSH level indicates that the thyroid gland is failing because of a problem that is directly affecting the thyroid (primary hypothyroidism). The opposite situation, in which the TSH level is low, usually indicates that the person has an overactive thyroid that is producing too much thyroid hormone (hyperthyroidism). Occasionally, a low TSH may result from an abnormality in the pituitary gland, which prevents it from making enough TSH to stimulate the thyroid (secondary hypothyroidism). In most healthy individuals, a normal TSH value means that the thyroid is functioning normally.

In most healthy individuals, a normal TSH value means that the thyroid is functioning normally.
TPO: The TPO gene provides instructions for making an enzyme called thyroid peroxidase. This enzyme plays a central role in the function of the thyroid gland. Thyroid peroxidase assists the chemical reaction that adds iodine to a protein called thyroglobulin, a critical step in generating thyroid hormones. Thyroid hormones play an important role in regulating growth, brain development, and the rate of chemical reactions in the body (metabolism).
TGAb: This test helps to detect possible thyroid problems. Thyroglobulin is a protein that is normally confined to the thyroid gland. It is the source of the thyroxine and triiodothyronine hormones in the body. The presence of autoantibodies to thyroglobulin can lead to the destruction of the thyroid gland. Such antibodies are more likely to appear after trauma to, or inflammation of, the thyroid gland. is one of the acute phase proteins that increase during systemic inflammation. It’s been suggested that testing CRP levels in the blood may be an additional way to assess cardiovascular disease risk. A more sensitive CRP test, called a highly sensitive C-reactive protein (hs-CRP) assay, is available to determine heart disease risk.

Description: Critical to your metabolism, thyroid function affects your energy level, heart rate, weight control, plus more.
Includes: Thyroid Panel w/TSH, Total T3, Reverse T3, Free T3, and Free T4
T-3 Uptake: A T3 resin uptake (also called a T3 uptake or T3RU) is performed as part of an evaluation of thyroid function. The thyroid is a gland in the neck that produces the hormones that help regulate many body processes, including growth, energy balance, body temperature, and heart rate. Thyroid function involves the interaction of many hormones, including triiodothyronine (T3) and thyroxine (T4). Both of these hormones exist in two forms in the blood. The more abundant forms are bound to a carrier protein called thyroxin-binding globulin (TBG), which helps transport the hormones through the body. The less abundant forms circulate unattached or "free." Only the free forms of the thyroid hormones (free T4 and free T3) are available to affect body processes. The T3 resin uptake is used by doctors to estimate the amount of TBG in the blood, and how much T4 and T3 in the blood is free form and available to affect the body. If there's either too much or too little TBG in the blood, the measurements of total T3 and T4 levels will be affected, which can make it difficult for doctors to tell whether a person actually has a thyroid problem without also knowing the results of the T3 resin uptake.
T4, total:A T4 test measures the blood level of the hormone T4, also known as thyroxine, which is produced by the thyroid gland and helps control metabolism and growth. The T4 test is performed as part of an evaluation of thyroid function. T4 measures the entire amount of thyroxine in the blood, including the amount attached to blood proteins that help transport the hormone through the bloodstream.
Free Thyroxine Index (T7): FTI stands for the Free Thyroxine Index and is also sometimes referred to as T7. It is a calculated value determined from the T3 uptake test and total T4 test and provides an estimate of the level of free T4 in the blood.
TSH (Thyroid Stimulating Hormone): The best way to initially test thyroid function is to measure the TSH level in a blood sample. A high TSH level indicates that the thyroid gland is failing because of a problem that is directly affecting the thyroid (primary hypothyroidism). The opposite situation, in which the TSH level is low, usually indicates that the person has an overactive thyroid that is producing too much thyroid hormone (hyperthyroidism). Occasionally, a low TSH may result from an abnormality in the pituitary gland, which prevents it from making enough TSH to stimulate the thyroid (secondary hypothyroidism). In most healthy individuals, a normal TSH value means that the thyroid is functioning normally.
T3, total triiodothryonine: Increased T3 often occurs in hyperthyroidism, but in approximately 5% of cases only T3 is elevated, “T3 toxicosis.” Do not confuse T3 with T3 uptake; these are two different tests. The latter is done very commonly as part of the usual thyroid profile. Less than 1% of T3 is unbound.
Reverse T3: Since thyroid hormone acts like our internal thermostat, thyroid hormones may be suppressed in times of stress. One way this is done is by converting the thyroid hormone T4 into an inactive form of the active T3 hormone called reverse T3. This lowers the amount of available active T3 which can lead to hypothyroid type symptoms.
Free T3: This test is used to evaluate thyroid function. It is primarily used to diagnose hyperthyroidism. It is also used to assess abnormal binding protein disorders and to monitor thyroid replacement and suppressive therapy.
Free T4: This test is used to evaluate thyroid function in individuals who may have protein abnormalities that could affect total T4 levels. It is used to evaluate thyroid function and monitor replacement and suppressive therapy.

Description: The national surge in chronic health conditions is prompting medical practitioners to seek new tools to better understand the underlying causes of disease. At the same time, the mapping of the human genome plus thousands of following studies is expanding our understanding of the role that genes play in our health. Genes influence not just serious conditions, but also many of the biochemical processes that influence our general health and wellness. Patients have long known that they are unique individuals, genetic testing allows unique insight into each person’s potential for wellness.
There are many options for genetic testing, but providers are increasing looking to single nucleotide polymorphism (SNP) testing to learn additional information that will inform treatment decision making now and into the future.
The genes in the panel provide information associated with:
Cardiac disease
Obesity and diabetes
Nutritional deficiencies
Cravings
What foods to eat
Memory and brain health
Mood disorders and insomnia
Bone health
Hormone imbalance
Kashi uses the latest in quantitative real-time polymerase chain reaction instrumentation with a high degree of sensitivity. SNP’s are only included in our panels when peer reviewed studies show there is a clear connection with treatment decision making, the studies are relevant across a range of population types, clinical intervention is indicated, and that nutritional or other lifestyle choices can affect the regulation of gene expression.
