Free T4 is the unbound form of the thyroid hormone thyroxine. It is crucial for regulating metabolism, energy levels, and growth. Measuring Free T4 helps diagnose and monitor thyroid disorders such as hypothyroidism and hyperthyroidism.
The Free T4 at-home blood test kit measures the level of free thyroxine (T4) in your bloodstream. Free T4 is the active form of the hormone produced by your thyroid gland and plays a vital role in regulating metabolism, energy production, and overall hormonal balance.
This blood test kit is ideal for anyone experiencing symptoms such as unexplained weight changes, fatigue, temperature sensitivity, or changes in heart rate. It’s also suitable for people monitoring known thyroid conditions or adjusting medication under medical supervision.
Follow the enclosed instructions to perform a simple fingerprick sample with the lancet. Collect enough blood into the TDL Tiny tube, seal it securely, label it, and mail it back using the prepaid envelope.
Tip: Warm your hands for a few minutes under warm water before sampling to improve blood flow and ease collection.
The Free T4 at-home blood test measures the amount of free thyroxine (T4) hormone in your bloodstream. It helps assess how well your thyroid gland is functioning.
Collect your sample using the included TDL Tiny blood collection kit. Simply prick your finger with the lancet, fill the small tube, seal it, and return it to our lab using the prepaid envelope.
Results are typically available within 2–5 working days after the laboratory receives your sample. You’ll get a secure email or phone notification when your report is ready.
Our at-home Free T4 kit matches the accuracy of clinic-based blood draws because it uses the same laboratory methods. Follow the instructions carefully to ensure a valid sample.
