Why is a prealbumin blood test done?
A prealbumin blood test is done to:
- Check for signs of a poor diet (malnutrition).
- Find out if you're getting enough nutrients, mainly protein, in your diet. Protein is important for tissue growth and tissue healing.
- Keep track of your nutrition while you're in the hospital or before and after surgery. Poor nutrition can slow healing and recovery.
- See how well supplements or protein replacement fluids are working.
