Prealbumin, helps carry Thyroid hormones and Vitamin A in the blood. A low level of albumin indicates malnutrition, liver disease or an inflamatory disease where low levels of prealbumin indicates infectious and chronic diseases related to the energy metabolism especially for children who do not grow and develop normally.
