FT4 is the unbound, active form of the thyroid hormone thyroxine. It regulates metabolism, energy production, and body temperature. Abnormal FT4 levels can indicate hypo- or hyperthyroidism.
TSH is produced by the pituitary gland to control thyroid hormone production. High TSH suggests an underactive thyroid, while low TSH may indicate an overactive thyroid. Measuring TSH helps diagnose thyroid disorders.
This home blood testing kit measures Free Thyroxine (FT4) and Thyroid Stimulating Hormone (TSH) to assess how well your thyroid gland is working. It's one of the most comprehensive at-home blood tests for thyroid health.
This blood test kit is ideal for anyone experiencing fatigue, unexplained weight changes, temperature sensitivity, or other symptoms of thyroid imbalance. It's also suitable for routine monitoring of existing thyroid conditions.
