Q: Which 2 common conditions in ICU may give falsely elevated Pre-Albumin level?
Answer:
1. Alcohol intake
2. Steroid administration
In acute alcohol intoxication, a leakage of proteins from damaged hepatic cells may cause a rise in the prealbumin level. Consequently, alcoholics may have elevated levels of prealbumin after binge drinking. It takes about 7 days when levels return to baseline. Also, serum prealbumin levels may rise during prednisone/steroid therapy.
