What lab value responds to both PEM and iron status?

Question

Quizplus · Accepted Answer

Transferrin is a lab value that responds to both PEM and iron status. It is a protein that transports iron in the blood and its levels decrease in cases of iron deficiency, which is common in cases of PEM. Therefore, it can be used as an indicator for both conditions. The other options (albumin, prealbumin, and retinol-binding protein) are also markers for nutritional status, but they are not directly related to iron status.
