Prealbumin(PA) Determination Reagent is an in vitro diagnostic quantitative test kit. Prealbumin is a protein that's made in your liver. Prealbumin helps carry thyroid hormones and vitamin A through your bloodstream. It also helps control how your body uses energy. This test is used to evaluate protein malnutrition, total parenteral nutrition, and liver dysfunction. Values are decreased in inflammatory processes, malignancy, protein malnutrition, and protein wasting diseases of the gut or kidney. Values are increased in Hodgkin's disease.
