Question

Quizplus · Accepted Answer

Plasma ferritin is the most sensitive indicator for iron store depletion because it reflects the amount of ferritin, the major iron storage protein in the body. As iron stores become depleted, plasma ferritin levels decrease, indicating that iron is being used up and not being stored anymore. Hemoglobin and hematocrit are not as sensitive because they only decrease after iron stores have been depleted for a longer period of time. Heme iron is not an indicator for iron store depletion, but rather a type of iron found in animal products that is more easily absorbed by the body.
