Which serum marker and value indicates potential malnutrition related to wound healing?

• A. Serum Albumin; values >4.5 g/dL indicate malnutrition
• B. Serum Albumin; values <3.5 g/dL indicate malnutrition and impaired healing
• C. Prealbumin; values <15 mg/L indicate malnutrition
• D. Total Protein; values <6 g/dL indicate malnutrition

Answer: (B)

Low serum albumin signals inadequate protein stores that are crucial for wound healing, because proteins provide the building blocks for tissue repair, immune function, and collagen formation. When albumin falls below 3.5 g/dL, it commonly reflects protein-energy malnutrition that can impair the body’s ability to heal wounds. This value is a standard clinical indicator of nutritional status over weeks and helps predict healing potential. Higher albumin levels, such as those above 4.5 g/dL, do not indicate malnutrition; they suggest adequate protein status and are not consistent with a malnutrition signal. While prealbumin can reflect more recent changes in nutrition, its interpretation is complicated by inflammation and other factors, so a value below 15 mg/L is not as straightforward a marker for wound healing in many clinical contexts. Total protein can be influenced by hydration and other variables and is less specific for assessing protein-energy deficiency in relation to healing.
