Indicators
An essential aromatic amino acid in humans (provided by food), Phenylalanine plays a key role in the biosynthesis of other amino acids and is important in the structure and function of many proteins and enzymes. Phenylalanine is converted to tyrosine, used in the biosynthesis of dopamine and norepinephrine neurotransmitters. The L-form of Phenylalanine is incorporated into proteins, while the D-form acts as a painkiller. Absorption of ultraviolet radiation by Phenylalanine is used to quantify protein amounts. (NCI04)
Tests
A prealbumin blood test measures prealbumin levels in your blood. Prealbumin is a protein that's made in your liver and is found in your blood. Prealbumin is used to make other proteins and helps carry thyroid hormones and vitamin A through your bloodstream. It also helps control how your body uses energy.
For everyone & professionals
Tests
The determination of the amount of prealbumin present in a sample.
For professionals
Indicators
This gene plays a role in the regulation of cell signaling. It is involved in cell migration, metabolic control, mitogenic activation and gene transcription.
Indicators
This gene plays a role in receptor tyrosine phosphorylation signal transduction, and is thought to play a role in cellular growth or differentiation, but an exact function has not been substantiated.
Indicators
This gene is involved in apoptosis, hormonogenesis, focal adhesion and the formation of intercellular junctions.
Tests
The pituitary hormone that regulates the thyroid; the primary first-line test for thyroid dysfunction.
For everyone & professionals
Indicators
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.
Tests
The determination of the amount of thyroxine binding globulin protein present in a sample.
For professionals
Indicators
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.
Indicators
A thyroid hormone containing 3 iodine atoms generally synthesized from levothyroxine, and has greater biological activity.
Indicators
Thyroid-stimulating hormone — the pituitary signal that regulates the thyroid and the usual first test of thyroid function.
