Comprehensive Thyroid Assessment: Measures TSH, free T4 (fT4), and free T3 (fT3) to provide an overview of thyroid function.
Convenient At-Home Collection: Uses a simple dried blood spot (DBS) sample, allowing testing from home without visiting a clinic.
Digital Results: Receive your results securely online with clear explanations and reference ranges.
Supports Early Insight: Monitoring thyroid hormones may help identify patterns associated with symptoms such as fatigue, weight changes, or mood fluctuations.
What This Test Measures
This panel analyzes three key biomarkers commonly used to assess thyroid function.
Thyroid-Stimulating Hormone (TSH)
Produced by the pituitary gland, TSH regulates the thyroid gland’s production of thyroid hormones. Changes in TSH levels may indicate altered thyroid activity.Free Thyroxine (fT4)
fT4 is the unbound, biologically active form of thyroxine, the main hormone produced by the thyroid gland. It plays an important role in metabolism and energy regulation.Free Triiodothyronine (fT3)
fT3 is the most active thyroid hormone and is primarily converted from T4 in the body. It influences metabolic rate, body temperature, and several cellular processes.
Measuring these markers together provides a broader picture of thyroid hormone regulation.

Why Choose Dried Blood Spot (DBS) Testing?
DBS technology offers several advantages for at-home thyroid testing:
Sample Stability: Thyroid hormones such as TSH, fT4, and fT3 remain stable in dried blood samples during transport.
Minimally Invasive: Only a small finger-prick blood sample is required.
Convenient Collection: Testing can be performed at home without visiting a clinic.
Validated Method: DBS testing has been widely evaluated for several laboratory markers when samples are collected correctly.
Who Should Consider This Test?
This thyroid panel may be relevant for individuals interested in monitoring thyroid-related biomarkers, including:
Individuals experiencing symptoms such as fatigue, weight changes, hair loss, mood changes, or sensitivity to cold.
People with a family history of thyroid conditions.
Individuals who want to monitor thyroid hormone levels over time.
Health-conscious individuals interested in tracking important hormonal markers.
Those seeking convenient at-home testing without visiting a clinic.
For personalized interpretation of your results, discussing them with a healthcare professional is recommended.
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
- Free Triiodothyronine (fT3): Free Triiodothyronine (fT3) is the unbound, active form of the thyroid hormone triiodothyronine (T3). It is crucial for regulating metabolism, energy levels, body temperature, and heart function. Measuring fT3 provides a direct assessment of the biologically active thyroid hormone available to tissues, reflecting current thyroid function more accurately than total T3 in many cases.
- Free Thyroxine (fT4): Free Thyroxine (fT4) is the unbound, active form of the thyroid hormone thyroxine in the bloodstream. It's crucial for assessing thyroid function because it directly reflects the amount of hormone available to regulate metabolism, growth, and energy levels. Measuring fT4 helps diagnose and monitor conditions like hyperthyroidism (too much) or hypothyroidism (too little) thyroid hormone.
How to prepare
For more consistent results, we recommend collecting your sample in the morning after an overnight fast (water only) and before taking any thyroid medication that day. If you use high-dose biotin or B-complex supplements, avoid them for 1–2 days before collection unless prescribed by your healthcare provider.
Frequently asked questions
What does the GetTested Thyroid Panel measure, and why are these specific hormones important?
The GetTested Thyroid Panel comprehensively measures three key thyroid hormones: Thyroid-Stimulating Hormone (TSH), Free Thyroxine (fT4), and Free Triiodothyronine (fT3). TSH, produced by the pituitary gland, regulates thyroid hormone production. Free T4 and Free T3 are the active, unbound forms of thyroid hormones circulating in your bloodstream, directly influencing your metabolism, energy levels, heart function, and mood. Analyzing these markers together provides a complete picture of your thyroid gland's function and helps identify potential imbalances affecting your metabolic health.
How does the GetTested Thyroid Panel work, and what is the sample collection process?
The GetTested Thyroid Panel utilizes a convenient at-home dried blood spot (DBS) sample collection method. This involves a simple finger prick to collect a few drops of blood onto a provided collection card. Once the sample is dry, you mail it back in the pre-paid envelope. This innovative DBS method offers significant advantages for these specific thyroid markers, ensuring sample stability and convenience compared to traditional venous draws, while maintaining high analytical accuracy at our CLIA-certified laboratories.
Who should consider taking the GetTested Thyroid Panel?
Individuals experiencing symptoms such as unexplained weight changes, fatigue, mood swings, hair loss, cold sensitivity, or difficulty concentrating should consider this test. It's also beneficial for those with a family history of thyroid issues, a desire to monitor their metabolic health, or for optimizing overall well-being. Regular monitoring through this panel can help inform targeted lifestyle adjustments, dietary choices, or supplement use, integrating into a broader wellness journey.
How accurate and reliable is the GetTested Thyroid Panel, especially given the dried blood spot (DBS) method?
The GetTested Thyroid Panel is processed in CLIA-certified laboratories, ensuring the highest standards of analytical accuracy and reliability. Our dried blood spot (DBS) methodology for TSH, fT4, and fT3 has undergone rigorous validation studies, demonstrating its equivalence and proven accuracy compared to traditional venous blood draws for these specific markers. This makes the at-home DBS collection a technically valid, convenient, and less invasive option, providing trustworthy insights into your thyroid function.
What is the turnaround time for results, and how will I interpret my thyroid panel report?
After your sample is received at our laboratory, you can typically expect your comprehensive results within 2-5 business days. Your detailed report will clearly present your TSH, fT4, and fT3 levels, indicating whether they fall within established normal ranges. While the report provides professional insights, we strongly recommend reviewing your results with a healthcare provider who can interpret them in the context of your individual health history and symptoms, guiding any necessary next steps.
