What is the prealbumin level in patients with mild malnutrition?

Under normal circumstances, prealbumin levels in patients with mild malnutrition typically range between 15 and 20 mg/dL. The detailed analysis is as follows:

Prealbumin is a liver-related protein and a precursor of albumin, synthesized by the liver and circulating in the bloodstream. Its primary function is to transport thyroxine, vitamin A, and other essential nutrients within and between cells, making it a key indicator for assessing nutritional status. Normal prealbumin levels may vary depending on the testing method used, but generally, the reference range for adults is 15–40 mg/dL. In cases of mild malnutrition, the body consumes some proteins as an energy source, leading to decreased prealbumin levels. When prealbumin levels fall below 15 mg/dL, this usually indicates severe malnutrition. Therefore, prealbumin levels in individuals with mild malnutrition are typically in the range of 15–20 mg/dL.

Prealbumin levels can be influenced by various factors, including liver disease, inflammatory stimuli, stress responses, and renal insufficiency. If low prealbumin levels are detected, timely medical evaluation and treatment are recommended to prevent disease progression and potentially serious complications.
