FT4 is produced by the thyroid gland and converted into FT3. Measuring FT4 helps assess thyroid gland function and hormone production.
FT3 is the active thyroid hormone that controls metabolism and energy production. Abnormal FT3 levels can indicate hyperthyroidism or hypothyroidism.
TSH is released by the pituitary gland to regulate thyroid activity. High TSH levels often signal an underactive thyroid; low TSH suggests an overactive thyroid.
The At-Home Thyroid Function Test (Thyroid Profile 3) measures key hormones—FT3, FT4 and TSH—that regulate your metabolism, energy levels and overall health. This home blood testing kit lets you conveniently monitor thyroid function wherever you are.
This at-home blood test is ideal for anyone experiencing:
You’ll perform a simple finger-prick to collect a small capillary blood sample into the TDL Tiny collection tube. Follow the step-by-step guide, seal the tube, then drop it in the post using the pre-paid envelope. No clinic visit required—perfect for at-home convenience.

The Thyroid Profile 3 measures Free T3 (FT3), Free T4 (FT4) and Thyroid Stimulating Hormone (TSH). These markers help diagnose hypothyroidism, hyperthyroidism and monitor treatment effectiveness.
You can take this at any time but ideally in the morning, fasting for 8–12 hours. Avoid vigorous exercise or caffeine before sampling to get the most accurate thyroid blood test kit results.
