Thyroid Test Plus – With Thyroid Antibodies

About this test

Key Benefits

Gain a comprehensive understanding of your thyroid health with convenient at-home testing, focusing on crucial markers for function and autoimmune activity.

• Comprehensive thyroid assessment: Evaluates key hormones (TSH, FT4, FT3) and thyroid peroxidase antibodies (TPOAb) for a complete picture.

• Convenient at-home sample collection: Utilize dried blood spot (DBS) technology for a simple, private finger-prick sample from the comfort of your home.

• Early insights into thyroid conditions: Identify potential imbalances or autoimmune responses indicated by TPOAb, often associated with Hashimoto's thyroiditis.

• Supports proactive health management: Provides data to discuss with healthcare professionals regarding symptoms like fatigue, weight changes, or hair loss.

What This Test Measures

This panel analyzes four critical markers to assess thyroid gland function and potential autoimmune involvement:

• TSH (Thyroid-Stimulating Hormone): Produced by the pituitary gland, TSH regulates the production of thyroid hormones. High TSH can indicate an underactive thyroid (hypothyroidism), while low TSH may suggest an overactive thyroid (hyperthyroidism).

• FT4 (Free Thyroxine): This is the active, unbound form of the main hormone produced by the thyroid gland. FT4 levels reflect the amount of thyroid hormone available to the body's tissues and cells.

• FT3 (Free Triiodothyronine): The most active thyroid hormone, FT3 plays a vital role in metabolism. Measuring free FT3 provides insight into the direct hormonal impact on body functions.

• TPOAb (Thyroid Peroxidase Antibodies): These antibodies target an enzyme in the thyroid gland. Their presence often indicates an autoimmune thyroid condition, such as Hashimoto's thyroiditis, and can be detected before significant changes in TSH, FT4, or FT3 levels.

Who Should Consider This Test

This test is suitable for individuals who:

• Are experiencing symptoms associated with thyroid imbalance, such as unexplained fatigue, weight fluctuations, mood changes, hair loss, or sensitivity to temperature.

• Have a family history of thyroid disorders or autoimmune conditions.

• Are women over 30, a demographic often more susceptible to thyroid issues.

• Seek convenient and private options for monitoring their thyroid health at home.

• Wish to proactively screen for thyroid function and autoimmune markers to inform discussions with their doctor.

Biomarkers included

• TSH: Thyroid-Stimulating Hormone (TSH), also known as thyrotropin, is a hormone produced by the pituitary gland. It plays a crucial role in regulating thyroid function by stimulating the thyroid gland to produce and release thyroid hormones (T3 and T4), which are vital for metabolism, growth, and development. Measuring TSH levels is a primary way to assess thyroid gland activity and diagnose thyroid di
• TPOAb (Thyroid Peroxidase Antibodies): TPOAb (Thyroid Peroxidase Antibodies) are autoantibodies that attack thyroid peroxidase, an enzyme critical for thyroid hormone production. Their presence indicates an autoimmune thyroid condition, such as Hashimoto's thyroiditis or Graves' disease, which can lead to hypothyroidism or hyperthyroidism, respectively. Measuring TPOAb helps diagnose and monitor these autoimmune thyroid disorders.
• Free T3 (fT3): Free triiodothyronine (fT3) is the unbound, biologically active form of the thyroid hormone T3. T3 plays a central role in regulating metabolic rate, energy production, temperature regulation, and many aspects of growth and tissue function. Measuring fT3 reflects the portion of T3 that is available to tissues, independent of variations in thyroid-binding proteins. fT3 is typically interpreted toge
• Free T4 (fT4): Free thyroxine (fT4) is the unbound fraction of the thyroid hormone T4 circulating in the blood. Because only the free hormone can enter cells, fT4 reflects the amount of thyroid hormone available to tissues and is a key marker of thyroid function. fT4 is commonly measured to help evaluate and monitor thyroid disorders—levels may be elevated in hyperthyroidism and reduced in hypothyroidism. It is

How to prepare

The sample should be collected in the morning, before 10:00 AM, on an empty stomach.

Frequently asked questions

What specifically does the GetTested Thyroid Test Plus measure and how does it contribute to understanding my thyroid health?

The GetTested Thyroid Test Plus measures TSH (thyroid-stimulating hormone), free T4 (thyroxine), free T3 (triiodothyronine) and thyroid peroxidase antibodies (TPOAb). Together, these markers provide an overview of thyroid hormone production and can indicate whether autoimmune activity may be affecting the thyroid. TPO antibodies are often present in autoimmune thyroid conditions such as Hashimoto’s thyroiditis.

How does the at-home dried blood spot (DBS) collection process work, and how accurate is this method for thyroid hormone and antibody testing?

Our Thyroid Test Plus utilizes a convenient dried blood spot (DBS) collection kit, which allows you to perform the sample collection privately from your home. Detailed, user-friendly instructions and an instructional video are provided to ensure a proper collection technique. The DBS method has been rigorously validated, demonstrating high correlation with venous blood draws for accurate measurement of thyroid hormones and antibodies. Our partner labs are CLIA certified, ensuring the reliability and precision of your results, comparable to traditional lab testing.

Who should consider using the GetTested Thyroid Test Plus, especially if they are already diagnosed with a thyroid condition?

This comprehensive test is ideal for individuals experiencing symptoms of thyroid dysfunction such as fatigue, weight changes, mood swings, or hair loss, and those with a family history of thyroid issues. Furthermore, it is a valuable tool for individuals already diagnosed with a thyroid condition, serving as a convenient method for ongoing monitoring of their thyroid function and antibody levels, helping them and their healthcare provider track the effectiveness of treatment regimens and adjust care as needed with regular testing and physician consultation.

What is the typical turnaround time for results from the Thyroid Test Plus, and what guidance is provided for interpreting my results?

Upon receiving your dried blood spot sample at our certified laboratory, results for the Thyroid Panel Plus are typically available within 2-5 business days. Your detailed results report will clearly outline your levels for TSH, Free T4, Free T3, TPO Antibodies, accompanied by their respective reference ranges. We strongly recommend discussing these results with your healthcare provider for personalized interpretation and to develop an appropriate action plan, ensuring a thorough understanding of your thyroid health status and any necessary next steps.
