A
protein indicator with half life of 20 days reflects prolonged protein depletion increase slowly with good feeding normal= greater than 3.5 mild depletion= 2.8-3.4 moderate depletion=2.1-2.7 severe depletion=less than 2.1
4
Q
Prealbumin
A
protein indicator with half-life of 48 hours sensitive to acute protein deficiency responds quickly may be elevated with corticosteroids or renal dz normal=16-30 mg/dl mild depletion=10-15 moderate depletion= 5-9 severe depletion= less than 5
5
Q
