Thyroxine is also called T4. T4 is a hormone that your thyroid gland makes. A T4 test measures the level of T4 in a sample of your blood. Too much or too little T4 may be a sign of a thyroid problem .
Pruebas
The determination of the amount of thyroxine binding globulin protein present in a sample.
Indicadores
A hormone synthesized and secreted by the thyroid gland containing four iodine atoms and is converted to triiodothyronine (T3) in the body, influencing metabolism and organ function.

Research record from J Clin Pathol, 2026-08-20. PMID 42331602.
Indicadores
The levorotatory isomer of the aromatic amino acid tyrosine. L-tyrosine is a naturally occurring tyrosine and is synthesized in vivo from L-phenylalanine. It is considered a non-essential amino acid; however, in patients with phenylketonuria who lack phenylalanine hydroxylase and cannot convert phenylalanine into tyrosine, it is considered an essential nutrient. In vivo, tyrosine plays a role in protein synthesis and serves as a precursor for the synthesis of catecholamines, thyroxine, and melanin.
Indicadores
Transthyretin (147 aa, ~16 kDa) is encoded by the human TTR gene. This protein is involved in both the binding and transport of retinol and thyroxine.
Indicadores
A thyroid hormone containing 3 iodine atoms generally synthesized from levothyroxine, and has greater biological activity.
Indicadores
This gene is involved in cell adhesion, differentiation, division and stress response.
Indicadores
This gene plays a role in signal transduction.
Indicadores
This gene is involved in brain development and neuronal specificity.
