An increase in serum albumin levels is most commonly associated with which condition?

• A. Edema
• B. Liver disease
• C. Dehydration
• D. Malnutrition/malnourishment

Answer: (C)

Serum albumin concentration reflects both liver synthesis and the volume of plasma in the blood. When you're dehydrated, plasma volume decreases (hemoconcentration), so the measured concentration of albumin goes up even though the total amount of albumin hasn’t increased. This is why dehydration can raise serum albumin levels.

In contrast, liver disease or malnutrition reduce albumin synthesis, leading to lower albumin levels, and edema often accompanies low albumin because of decreased oncotic pressure. So the pattern of a higher albumin concentration most commonly points to dehydration rather than the other conditions.
