The following is a list of what is included in the item above. Click the test(s) below to view what biomarkers are measured along with an explanation of what the biomarker is measuring.

T3 Uptake

T3 uptake is also known as T3 Resin Uptake (T3RU) or Thyroid Uptake. It estimates how much thyroid hormone-binding proteins are available in the blood through a calculation based on levels of T3 or T4 added to a person's blood specimen.

Also known as: Free T3, FT3, T3 Free

T3, Free

This test measures the amount of triiodothyronine, or T3, in the blood.

Also known as: Triiodothyronine

T3, Total

Triiodothyronine (T3) is a thyroid hormone. It plays an important role in the body's control of metabolism.

Also known as: Free T4, FT4, T4 Free

T4, Free

The free T4 test is not affected by protein levels. Since free T4 is the active form of thyroxine, the free T4 test is may be a more accurate reflection of thyroid hormone function.

Also known as: T4 Thyroxine Total

Free T4 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.

T4 (Thyroxine), Total

This test measures the amount of thyroxine, or T4, in the blood. T4 is one of two major hormones produced by the thyroid gland. The total T4 test is used to help diagnose hyperthyroidism and hypothyroidism. It is a useful test but can be affected by the amount of protein available in the blood to bind to the hormone.

Also known as: Thyroid Stimulating Hormone, Thyroid Stimulating Hormone (TSH), Thyrotropin

TSH

A TSH test is a lab test that measures the amount of thyroid stimulating hormone (TSH) in your blood. TSH is produced by the pituitary gland. It tells the thyroid gland to make and release thyroid hormones into the blood.
*Important Information on Lab Test Processing Times: Ulta Lab Tests is committed to informing you about the processing times for your lab tests processed through a national lab. Please note that the estimated processing time for each test, indicated in business days, is based on data from the past 30 days across the 13 laboratories for each test. These estimates are intended to serve as a guide and are not guarantees. Factors such as laboratory workload, weather conditions, holidays, and the need for additional testing or maintenance can influence actual processing times. We aim to offer estimates to help you plan accordingly. Please understand that these times may vary, and processing times are not guaranteed.

The Thyroid Health - Basic Plus Lab Panel panel contains 6 tests with 7 biomarkers .

Thyroid Health Basic Plus | Ulta Lab Tests Curated Panel

Brief Description: The Thyroid Health - Basic Plus Lab panel is an intermediate-level diagnostic tool designed to provide a more comprehensive assessment of thyroid function compared to the Basic Lab panel. It includes six key tests: T3 Total, T3 Uptake, T3 Free, T4 Total, T4 Free, and Thyroid Stimulating Hormone (TSH). This panel offers a broader perspective on thyroid hormone levels, thyroid gland activity, and pituitary gland feedback, aiding in the diagnosis and management of thyroid disorders.

Collection Method: Blood Draw Thyroid Health - Basic Plus Lab Panel Test Blood Draw | Ulta Lab Tests
Specimen: 6 mL Serum Thyroid Health - Basic Plus Lab Panel Test Specimen Type Serum | Ulta Lab Tests

Test Preparation: No preparation required.

External Test Interference: If you've had a fluorescein dye test (such as for an eye exam), wait at least 3 days before having your TSH test drawn. If you are on hemodialysis, wait 2 weeks. Fluorescein can cause falsely low TSH results.

When and Why the Thyroid Health - Basic Plus Lab Panel May Be Ordered

The Thyroid Health - Basic Plus Lab panel is typically ordered when healthcare providers suspect thyroid dysfunction based on clinical symptoms or when follow-up testing is required after initial screening with the Basic Lab panel. It is especially useful for individuals with symptoms such as fatigue, weight changes, mood swings, or an enlarged thyroid gland (goiter). This panel allows for a more detailed evaluation of thyroid health.

What the Thyroid Health - Basic Plus Lab Panel Checks For

  1. T3 Total: Measures the total amount of triiodothyronine (T3) hormone in the blood, including both the bound and free forms. T3 plays a crucial role in regulating metabolism and energy production.

  2. T3 Uptake: Assesses the availability of binding proteins for T3, providing information on the capacity to transport T3 in the bloodstream.

  3. T3 Free: Specifically measures the free, unbound T3 hormone, which is biologically active and available for use by the body's cells. Elevated or decreased levels can indicate thyroid dysfunction.

  4. T4 Total: Measures the total amount of thyroxine (T4) hormone in the blood, including both bound and free T4. T4 is a key thyroid hormone involved in regulating metabolism.

  5. T4 Free: Specifically measures the free, unbound T4 hormone, which is the biologically active form available for cellular uptake.

  6. Thyroid Stimulating Hormone (TSH): Produced by the pituitary gland, TSH regulates the thyroid's production of T3 and T4. Elevated TSH levels may indicate an underactive thyroid (hypothyroidism), while low TSH levels may suggest an overactive thyroid (hyperthyroidism).

Getting a Deeper Understanding of Your Thyroid's Health

While the Basic Plus Lab panel offers a more comprehensive view of thyroid function, the Advanced and Comprehensive panels provide even greater insights and are suitable for complex cases.

  1. Thyroid Health - Advanced Lab Panel: Adds T3 Reverse, Thyroid Peroxidase Antibodies, and Thyroglobulin Antibodies tests. This panel is ideal for individuals with suspected autoimmune thyroid diseases, providing insights into autoimmune aspects and reverse T3 levels, which can indicate thyroid dysfunction.

  2. Thyroid Health - Comprehensive Lab Panel: The most extensive panel, it encompasses all tests from the Advanced Lab panel and introduces Thyroxine Binding Globulin and Thyroid Stimulating Immunoglobulin tests. This panel offers the most thorough assessment of thyroid health, including hormone transport and thyroid autoimmunity, suitable for complex thyroid conditions.

Conditions Detected by the Thyroid Health - Basic Plus Lab Panel

The Basic Plus Lab panel can detect a range of thyroid disorders, including hypothyroidism (elevated TSH and low T4 or T3 levels) and hyperthyroidism (low TSH and elevated T4 or T3 levels). It can also identify cases where thyroid hormone transport or binding proteins are affected.

Utilization of Thyroid Health - Basic Plus Lab Panel Results by Healthcare Professionals

Healthcare professionals use the results of the Basic Plus Lab panel to diagnose thyroid disorders, determine their severity, and guide treatment decisions. Abnormal findings may lead to further testing, medication adjustments, or referrals to endocrinologists. For example, elevated TSH and low T4 levels may indicate primary hypothyroidism, prompting thyroid hormone replacement therapy.

The Thyroid Health - Basic Plus Lab panel provides valuable insights into thyroid function, helping healthcare professionals identify and manage thyroid disorders more effectively. By assessing a broader spectrum of thyroid hormones and pituitary feedback, this panel aids in diagnosing various thyroid conditions and guides treatment decisions, ultimately improving patient outcomes and overall thyroid health.

We advise having your results reviewed by a licensed medical healthcare professional for proper interpretation of your results.
