Hemoglobin absorption coefficient
WebNational Center for Biotechnology Information Web7 apr. 2024 · Blood loss, decreased iron intake, and impaired iron absorption could contribute to iron deficiency . Gestational iron storage and the absorption of dietary iron are important for the maintenance of iron homeostasis. Ferritin is a protein form which stores iron and serves as a preliminary predictor of lower hemoglobin and anemia [13,14].
