Prealbumin is a protein that is mainly produced by the liver. It is a transport protein for thyroid hormones and exists in the circulation as a retinol-binding-prealbumin complex. Low prealbumin scores means, that one most likely requires a nutritional assessment. Prealbumin helps carry thyroid hormones and vitamin A through one’s bloodstream. It also helps regulate the use of body energy. If your prealbumin levels are lower than normal, it may be a sign of malnutrition. Low prealbumin scores may also be a sign of liver disease, inflammation, or tissue death (tissue necrosis). High prealbumin scores may be a sign of long-term (chronic) kidney disease, Hodgkin disease, steroid use, or alcoholism. Anti-human prealbumin can be used to diagnose if one is getting enough nutrients, especially protein, in ones diet. It can also Help diagnose certain infections and chronic diseases.
