Blood is life—but not all blood is the same. While some blood groups are common and easy to find, others are extremely rare. In emergencies, especially during surgeries or accidents, or for patients with unique medical needs, rare blood groups can make the difference between life and death.
What Makes a Blood Group Rare?
Blood types are determined by the ABO system (A, B, AB, O) and the Rh factor (positive or negative).
The most common blood type is O+.
The rarest is AB-, found in less than 1% of people worldwide.
Other rare groups include B-, O-, and certain rare sub-types like Bombay Blood Group (hh), found mostly in parts of India.
Why Rare Blood Groups Are So Important
Limited Availability—Fewer donors mean hospitals often struggle to find rare blood in emergencies.
Compatibility Issues—Patients with rare types can only receive blood from the same or compatible rare donors.
Life-Saving in Emergencies – For accident victims, cancer patients, and surgeries, having access to rare blood can save lives instantly.
Essential for Children & Newborns – Babies with certain conditions need rare blood for survival.
