A

3.5-5.5 g/dL

22
Q

What happens if serum albumin is low?

A

may be malnourished, may cause tissue edema, may be a sign of metabolic stress or inflammation…. correlated with pressure ulcer severity

Q

What happens is serum prealbumin is low?

A

may be malnourished, may be a sign of metabolic stress or inflammation, mortality rate increases as prealbumin decreases
