What albumin level indicates protein malnutrition?

The correct indication of protein malnutrition through albumin levels is a serum albumin level below 3.5 g/dL. A level of 2.5 g/dL is considered significantly low and would strongly suggest protein malnutrition or an acute inflammatory response. A level of 3.0 g/dL is also considered low and indicates the possibility of malnutrition.

A level of 3.7 g/dL falls within the normal range (typically 3.5 to 5.0 g/dL) and does not suggest protein malnutrition. While it might be on the lower end of normal, it does not indicate a malnourished state. A level of 4.0 g/dL is well within the normal range and suggests adequate protein levels in the body.

In the context of protein malnutrition, it is essential to monitor serum albumin levels, as they provide insight into an individual's nutritional status and liver function. Lower levels are critical in assessing malnutrition, whereas higher levels indicate sufficient protein intake and synthesis.
