Teacher: Now, understand the problem? Solve this instance: Question: Does neutrophil gelatinase-associated lipocalin ( NGAL ) reflect iron status in haemodialysis patients?
Answer: The findings demonstrated that HD patients have altered NGAL values probably because this protein is involved in the maintenance of iron equilibrium. Finally, NGAL might be proposed as a new tool in the assessment of iron deficiency and in the management of iron therapy for HD patients.
