In the evaluation of malnutrition, which of the following proteins has the shortest half-life and thus is most predictive of recent nutritional status?

E. Transferrin

D

half life of
albumin=20 days
fibronectine=2-3 days
retinol binding protein = 12 hr
pre albumin= 2 days
Transferrin= 8days...
m confused between retinol binding protein and prealbumin...:notsure:
glycated retinol binding protein is used for evaluating sugar level...and prealbumin is an indicator for protein status....so would go with...prealbumin

definitely C. RBP is not only used for sugar level. It could be used with prealbumin to detect subclinical malnutrition and monitor the effectiveness of dietary treatment. So C must be the best answer
