A transferrina é uma proteína que desempenha um papel importante no transporte de ferro no organismo. Seus níveis podem indicar diferentes condições. Níveis abaixo de 200mg/dL podem indicar desnutrição proteico-energética. Além disso, os níveis de transferrina podem ser alterados em casos de anemia por deficiência de ferro, hepatite aguda, perda crônica de sangue, neoplasias, doença renal, desidratação, uso de contraceptivos orais, entre outros.
