Diagnosis of transfusion dependent anemia is challenging because this anemia is caused by multiple diseases. [12] Therefore, other than diagnosing anemias that require transfusion, diagnosis for the two main causes (beta-thalassemia and myelodysplastic syndromes) of transfusion dependent anemia is also important.

Transferrin is an iron-binding protein present in blood plasma; transferrin acts as a transporter, carrying iron through blood and providing cells with the metal through endocytosis. Transferrin is highly specific to iron (III), and binds to it with an equilibrium constant of 10 23 M −1 at a pH of 7.4.
TDT requires regular blood transfusions, typically every two to five weeks. TDTs include beta-thalassemia major, hemoglobin H disease, and severe HbE/beta-thalassemia. NTDT does not need regular transfusions but may require transfusion in case of an anemia crisis. [9]
If someone is severely iron deficient and anemic, and their hemoglobin is dangerously low, a blood transfusion may be needed. “But, we try to avoid that unless absolutely necessary,” O ...
Transfusion dependent anemia is a form of anemia where ongoing blood transfusion are required. [91] Most people with myelodysplastic syndrome develop this state at some point in time. [92] Beta thalassemia may also result in transfusion dependence. [93] [94] Concerns from repeated blood transfusions include iron overload. [92]
Long-term transfusion therapy (in those with transfusion dependent beta thalassemia) is a treatment used to maintain hemoglobin levels at a target pre-transfusion hemoglobin level of 9–10.5 g/dL (11–12 g/dL in those with concomitant heart disease). [8] To ensure quality blood transfusions, the packed red blood cells should be leucoreduced.
In adults, blood transfusion is typically recommended when hemoglobin levels are below 70 g/L (7 g/dL) in those who have stable vital signs, unless they have anemia due to a haematinic deficiency. Transfusing at a restrictive haemoglobin threshold of between 70 g/L to 80 g/L (7 to 8g/dL) decreased the proportion of people given a red blood cell ...
A 2013 study of over 400,000 people admitted to US hospitals found that 74% developed anemia at some point during their hospital stay. [5] Iatrogenic anemia is of particular concern in intensive care medicine, [6]: 629 because people who are critically ill require frequent blood tests and have a higher risk of developing anemia due to lower hemoglobin levels and impaired production of red ...
