Prealbumin 428mg/L is not normal, belongs to the elevated state, no need to be overly nervous, it is recommended to retest and follow the doctor’s advice to receive consultation and treatment.
Prealbumin is a protein synthesized by the liver with a smaller molecular weight than albumin. Because of its short half-life, it is often used to reflect liver cell damage at an early stage, and its plasma concentration is significantly affected by nutritional status and liver function.
The normal reference value of prealbumin is 280~360mg/L, so 428mg/L is an elevated state. In general, mild elevation of prealbumin level may occur if excessive protein foods are consumed, or when blood is concentrated. Prealbumin blood concentration decreases in acute inflammation, malignancy, cirrhosis or nephritis.
Therefore, it is recommended to seek medical attention for retesting to clarify the cause.
