Thalassemia is an inherited blood disorder that affects the body's ability to produce healthy hemoglobin. For patients with the more severe form, thalassemia major, regular blood transfusions — often every two to four weeks — aren't a one-time treatment but a lifelong requirement, starting frequently in early childhood.

That recurring need makes thalassemia patients some of the most predictable, and most demanding, consumers of the blood supply. A single patient can require dozens of units a year, every year, for life, which is very different from the one-off need of a surgery or accident patient.

For blood banks and platforms like RaktKhoj, this means scheduling matters as much as raw donor count: a steady base of repeat donors who can be relied on every few months is more valuable to thalassemia care than a large pool of one-time donors. It's also why donor registries that track last-donation dates and send timely reminders play a real role — predictable donor availability is what keeps a thalassemia patient's transfusion schedule from slipping.
